The crystal contains the secrets of the universe, and crystal is expanding the space of modern life. German philosopher Cassier said in "Human Theory": "Science is the last step in the development of human intelligence, and can be regarded as the highest and most unique achievement of human culture." Science and technology are closely linked, people The two are often referred to simply as "technology". From this perspective, the use and achievements of crystal in high-tech fields should be an important part of crystal culture. 

    The relationship between crystal and high technology attracted special attention from the world of crystal gifts after entering the 20th century, because it played a wonderful role in the two world wars and shocked the world. Then it set off a global search for crystal and research crystal , The upsurge of developing crystal and silicon series products. After long-term research and development, crystal is more well known. 

    Crystal has 16 kinds of excellent physical and chemical properties such as transparency, hardness, elasticity, birefringence, high melting point, directivity, pressure resistance, thermal conductivity, optical rotation, acid resistance, alkali resistance, piezoelectric effect, etc. Technology has unique advantages. Through practice and comparison, the world crystal expert Almozova of the former Soviet Union and the United States' Rosse Joan have repeatedly praised: the East China Sea has a large amount of crystals, large body, high quality and high silicon content, which is rare in the world. 

    They all predicted: "The East China Sea will be the quartz center of the world." As the hometown of crystal pride, the East China Sea has always been in the leading position in the development of crystal in the four categories of piezoelectric crystal, optical crystal, smelting crystal, and synthetic crystal, and has become a popular item in the high-tech office gift decoration kit technology field. 

    Piezoelectric crystal refers to its single crystal with high purity without any inclusions, impurities and nodules. Because crystal has a positive and negative piezoelectric effect and has advantages that other piezoelectric materials cannot match, it is widely used to manufacture quartz resonators, filters, ultrasonic generators and various measuring instruments. 

    Quartz resonator is a key component of wireless electronic industrial equipment. It is characterized by a high degree of stability, sensitivity and a relatively wide frequency range. It can be universally installed in wireless communication transmitters, receivers and radio measuring instruments, such as radio telegrams, radio facsimile, wireless television, wireless broadcasting and so on. It is also widely used in artificial earth satellites, missiles, supersonic aircraft, rockets, ships, radar, electronic calculators, quartz watches, and various long-distance manipulation, tracking, navigation and other equipment. In the 1990s, miniature quartz resonators appeared. The crystal slices contained in the flyhead-sized resonators were as thin as cicada wings. The technicians of Donghai Crystal Material Factory actually cut a 1.8-cm-long crystal rod into 80 round wafers, which shows the degree of precision. Its emergence has accelerated the modernization of electronic products, making "Big Brother", computers, etc. smaller and smaller, and the "heart" of televisions and air conditioners simpler. The world's demand is growing at a rate of hundreds of millions every year. At present, the annual output capacity of Donghai Crystal Materials Factory is only 20 million wafers, which shows the great potential for development. 

    Filters are widely used in various carrier devices in wired communication, such as carrier phones, which can be used on the same lead of carrier multi-channel communication at the same time, using several pairs to thousands of phones without interfering with each other. 

    Ultrasonic generators are often used on ultrasonic detectors to find cracks and pores in metal products and hard plastics. Used in ultrasonic detectors, it can measure the depth of the seabed, the topography of the seabed, and detect fish. 

    Voltage crystals are also used in various measuring instruments such as pressure gauges and high-pressure instruments to measure the pressure of bridges, machines, and barrels. 

    Optical crystal refers to pure colorless and transparent single crystal without double crystals, nodules, various inclusions, cotton, cracks, and blue needles. According to the special optical properties of crystal, as optical materials, one is made into a variety of instrument lenses, which can be photographed in the dark through ultraviolet light, observed, photographed in the cloud and remotely. The second is to make the prism and lens of the spectrometer to measure the content of mineral elements. It is made into a quartz filter to observe and shoot the sun. It is made into an ultraviolet lamp and used for sterilization and treatment. Make a polarimeter lens to measure the concentration and content of polarimetric substance. It is made into a telescope microscope, which can observe celestial bodies in large, and bacteria and cells can be seen in small. 

    Smelt crystal refers to the crystals formed by filtering and remaining the impurities-free crystal fragments after melting and cooling. It is made of crystal with high temperature resistance, acid and alkali resistance and linear expansion coefficient. It is used in the quartz glass industry to make quartz glass pipes, utensils, optical glass, and synthetic crystal materials. It is also widely used in electronics, chemical industry, metallurgy, communications, Automobile, machinery manufacturing, medical utensils and instrument industry. Since the founding of the People's Republic of China, Donghai 105 Mine, Donghai Optical Instrument Factory has developed and processed crystal products according to the needs of the country, and has made important contributions to the country's cutting-edge science. 

    Synthetic crystal, also known as artificial crystal, is a product of modern high technology under the condition that natural crystal resources are becoming scarcer. It is a kind of artificial conditions that imitate the specific conditions required for the formation of natural crystals in nature. The production of synthetic crystals in Donghai County occupies a considerable position in China. It uses the world-wide hydrothermal synthesis crystal process. Donghai Crystal Factory has two of the country's largest hydrothermal processes for producing autoclaves. At present, tea, purple, green, yellow, red, black and other colored crystals have been produced using hydrothermal synthesis technology. The crystal synthesized by hydrothermal method has no difference in physical, chemical properties and internal structure from natural crystal except that it can see the seed crystal in the crystal and the regular hexagonal column and hexagonal pyramid, and the crystal surface is uneven and stepped. , And impurities and defects are quite few. Therefore, after the synthetic crystal and its products entered the market, they were quickly recognized internationally. 

    In a word, crystal has formed an indissoluble bond with science, science has formed an inseparable bond with life, and the role of crystal has become ubiquitous and omnipresent.  

    Now, the TV, computer, mobile phone and network communication industries are rapidly expanding the scope and frequency of use. But no matter how the development of these industries, such as TV sets from black and white to color, from analog to digital; the development trend of telecommunications from the digitalization and integration of telecommunications networks to the direction of intelligence, mobility, broadband and personalization, all Components made of wafers are always inseparable. 

    The most influential use and achievements of Crystal in the field of high technology are the magical power shown in the two world wars, the Gulf War and the Iraq War. We may wish to review the history and look forward to the future of crystal in the high-tech field. 

    During the First World War, the French fleet was heavily hit by German submarines. French physicist Lang Zhiwan used the principle of the crystal piezoelectric effect to connect a crystal to an alternating current to generate strange ultrasonic waves frequently. Once the ultrasound encounters an obstacle, it will send a return signal accordingly. Soon, the powerful ultrasonic radiator made of piezoelectric crystal was applied, which made it easy for the French army to measure the distance of the German submarine, which caused the German submarine to be defeated and was hit hard. 

    During the Second World War, with the rapid development of science and technology and the stimulation of war, the weapons and military equipment of the participating countries rapidly expanded and upgraded their ranks. The battle of weapons in a bloody battle between dozens of countries involved consumed a lot of crystals. In 1945 alone, more than 500 tons of piezoelectric crystals were used in a country in the United States; the former Soviet Union was in short supply and had to endure painstakingly, cutting out the crystal exhibits and craft products in the museum. Natural crystals are far from meeting the needs of society. The first result is to promote and accelerate the production and development of synthetic crystals. The second is to intensify the crystal predation of the occupied country by the occupying power. For example, after Japan occupied Donghai County as early as 1939, it forced farmers to build the Xuhai Highway, and all the crystals dug out were driven away. They also drove farmers to dig the crystals and bought or looted them. The large crystal of Fangshan County in Donghai County exhibited by Nanjing Quanye Association was also captured by the Japanese army and used in military technology to slaughter the Chinese people. 

    Judging from the use and importance attached to crystal by several major powers in World War II, it is clear that the power of crystal in military high technology. 

    With the rapid development of science and technology in the past two decades, major changes have taken place in the world's military, especially in advanced countries. The form of war is changing from a mechanized war to an informatized war. The military's informatized combat capability is becoming increasingly decisive; "non-contact" has become the most prominent feature of the new type of war. Such as the Gulf War in 1991, the Kosovo War in 1999, the Afghanistan War in 2001 and the Iraq War in 2003. In these four wars, with the power of high technology, the US military defeated the enemy in a short period of time. 

    The reason is that crystal and quartz have served as the "heart" components of high-tech weapons. It is truly magical in modern wars, and it is a hundred times more powerful than Sun Wukong's seventy-two changes. In addition, high-tech weapons can also deal with the huge natural disasters facing mankind suddenly. For example, scientists are seeking to use nuclear weapons to destroy comets and spaceflights impacting on the earth, to avoid possible disasters or major disasters on the earth. Also, since the Soviet Union launched its first artificial satellite on October 4, 1957, humans have produced about 2,000 tons of garbage in space (estimated by British scientist Rowell), and now NASA is experimenting with a crystal , A laser "broom" made by quartz products to clean up the garbage of artificial machines in the universe. This is a typical idea of using high-tech means to overcome the negative effects of high-tech. This idea may soon become a reality. 

    According to a special report on July 26, 2003, the latest issue of "Nature" magazine reported that American scientists have developed an ultra-miniature rotor, which is known as "another new breakthrough" in the field of nanotechnology. The missing role. As the American professor Frank Dallland said: The "information exchange era" in which we live should actually be the "Crystal Age." One day, people will lift the mysterious veil of crystal with the sword of science, which will make the crystal show its magic.
