Sapphire refers to non red alumina (Al2O3). Sapphire containing impurities is very long ago as a gem, because it has a variety of optical, mechanical, electrical, thermal and chemical properties, so it is widely used in industrial and other fields, and the application is still in constant expansion.

The main uses of the sapphire include LED and LED base. Sapphire is an important raw material for the production of chips, accounting for 10% of the raw material of the LED chip. After the third quarter of 2010, the global sapphire production in the top two companies have price increases, a direct impact on the LED chip and the package price increases.
