Sapphire technology is diversifying, and the Czochralski method is gradually becoming the market mainstream.
1. Overview of the Sapphire Industry Sapphire crystals have very stable chemical properties, characterized by a high melting point (2050°C), great hardness (Mohs hardness of 9, second only to diamond), and excellent transparency, thermal conductivity, and electrical insulation. They also possess good mechanical properties, wear resistance, and erosion resistance, along with outstanding optical and physicochemical characteristics. Therefore, sapphire is an extremely important basic material in the microelectronics and optoelectronics industries, widely used in various fields such as semiconductors, microelectronics, optoelectronics, information display, optical communication, lasers, precision machinery, and national defense and military applications. With the development of science and technology,
