                                   Applications and Processing Methods of Sapphire Crystals (I)

Sapphire crystal refers to non red aluminum oxide, which has the characteristics of high sound speed, high temperature resistance, corrosion resistance, high hardness, high light transmittance, and high melting point (2045 ℃). It is a very difficult material to process, so it is often used as the material of photoelectric components. Sapphire crystal is an extremely important basic material for modern industry, especially for microelectronics and optoelectronics industry. It is an upstream product in the LED new light source industry chain. Sapphire crystal is widely used in high-tech fields of semiconductor, chemical industry, aviation, aerospace, national defense and other industries, and has great social and economic benefits.

Sapphire crystal and three generation semiconductor materials, such as monocrystalline silicon, gallium arsenide, gallium nitride and silicon carbide, are different in quality but belong to the same kind (crystal). Many crystals support, compete and entangle each other.

Sapphire crystal growth and slicing project is the core link of the LED industry chain. Its products are one of the important upstream raw materials of the LED industry. LED is the abbreviation of light emitting diode. It has the characteristics of high luminous efficiency, environmental protection, long life, small size, etc. It is now the world Zui's advanced lighting technology in the world. Sapphire chip has become the key material for making white/blue/green LED, and has been in short supply in LED application field.
