Describe of Sapphire:

Sapphire ingots are aluminum oxide crystals, which are used to produce sapphire substrates, the most advantageous upstream raw material for LEDs. Under the rapid development of LEDs, the industry has entered a period of vigorous development in an all-round way. With the full penetration of the LED industry, the demand for the most upstream sapphire products will continue to maintain rapid growth and have broad development prospects. Various artificial growth techniques for sapphire crystals have been continuously developed, and more than ten crystal growth methods have been developed, such as the flame melting method, pulling method, and Kyropoulos method.
