Crystal (crystal) is a clear diffraction pattern of the solid, in which atoms or molecules arranged in space according to certain rules cycle repeatedly. Periodic arrangement of atoms or molecules in a crystal having a three-dimensional space, separated a certain distance is repeated, the crystal structure of such a periodic law is the most basic features. Solid material into crystalline and amorphous. From a macro point of view, natural condensation, free from outside interference and the formation of the crystal has its own unique, symmetric shapes, such as cubic salt; ice hexagonal prism; alum was octahedron and so on. When the crystal absorbs heat from the outside, its internal molecular, atomic average kinetic energy is increased, the temperature began to rise, but does not destroy its space lattice quasicrystal material remained regular arrangement. While continuing endotherm reaches a certain temperature ── melting point, the molecule, the intensity of atomic motion can destroy its regular arrangement, space lattice also began to disintegrate, so the crystals begin to become liquid. In the crystal transformation from solid to liquid, the heat absorption part by part to disrupt the crystalline lattice of the space, the temperature of the solid-liquid mixture is not raised. When the crystal is completely melted, along with crystal materials absorb heat from the outside, the temperature began to rise. Rather than due to the crystal arrangement of molecules, atoms irregular, without disrupting its space lattice after absorption of heat, only to increase the average kinetic energy, so when absorbing heat from the outside, then the hard-soft photoelectric crystal materials, and eventually liquid. Glass, rosin, asphalt, and the rubber is a common non-crystalline. Data show that 2012 profit sapphire manufacturers facing a difficult situation, it can be seen from Taiwan 12 LED sapphire manufacturers earnings report, Taiwan 12 sales sapphire larger enterprise, Xin crystal diamond, crystal beauty applications, such as 9 trillion Yuan Science and Technology Home LED sapphire listed company's total revenue of about 1.52 billion, down 25%. Where eight revenue setbacks, Xin Jing personal gain revenue by about 328 million yuan to strengthen crystal materials, down 34%. Jingmei application revenue of about 316 million yuan, down 24%. Largest decline was close crystal optoelectronics, 2012 revenue of about 030 million yuan, down 63%. Zhang standard LED Engineering Research Institute (GLII) Director believes that China Taiwan region LED sapphire market size appeared in 2012 mainly due to the recession that product prices and a sharp decline compared to 2011, resulting in a number of LED sapphire manufacturers operating conditions in a "growth without increasing the amount of "embarrassment. Last year was a crying sapphire dramatic signs of the market this year, ostensibly to round up business for a long time trying to ease the LED sapphire "life insurance" dilemma have a positive effect, but the outlook for continued growth potential, industry insiders have expressed the need to continue to wait and see . Currently, the ingot prices did not transfer to the common substrate, as well as high-PSS substrate downstream market, in view of the sapphire substrate had still some companies have stock ingot, round up short in a limited impact on the price of sapphire substrates . Recently, Dr. Engineering LED CEO Xiaofei Engineering Conference in Guangzhou, said that as of May this year, China Sapphire less than 40% capacity utilization, sapphire industry outlook in the short term can not be blindly optimistic.
