                                                          What are the functions of sapphire crystal?

Sapphire crystals have An interesting combination of mechanical, optical, and thermal properties with zero porosity. Because of these characteristics, sapphire crystal products have been widely used in technology. As an important technical crystal, sapphire crystal has been widely used in many fields such as science and technology, national defense and civil industry, and electronic technology.? Such as infrared window materials, substrate substrates in the field of microelectronics, laser substrates, optical elements and other applications. Sapphire crystal, chemical composition is aluminum oxide, chemical formula（ α- Al2O3) is composed of three oxygen atoms and two aluminum atoms in the form of covalent bonds. The crystal structure of sapphire is hexagonal lattice structure. Its great demand for zui is as raw materials for optical and electronic instrument manufacturing. Sapphire crystal can be used for spraying silicon crystal plate（ КНС Structure), on which radiation stable and fast reaction integrated circuits are manufactured（ ИС)。 Sapphire crystal can also be used as the substrate of GaN chip and its solid melt, which is the basis for forming rainbow spectral diodes of various colors. Under the same brightness conditions, its power consumption is 10-15 times lower than that of incandescent lamps.

Manufacturing process of artificial sapphire: raw material preparation → raw material filling and crystal seed erection → furnace body vacuumizing → furnace body heating (furnace body is added with molybdenum and tungsten heat shields) → raw material melting → crystal seed fusion → crystal neck growth → crystal growth → crystal separation from crucible (most crucibles here are high temperature resistant) → Cool → Remove crystals. Shi At present, there are mainly two kinds of crystallization processes in the world. One is the crystallization process originated from the former Soviet Union: foaming process; The other is the crystallization process from the United States: water heat exchange method.
