Guizhou 100 kg single crystal LED sapphire crystal Asia's largest

Guizhou 100 kg led sapphire crystal project successful trial production of qualified 105 kg sapphire crystal hit Asian single LED sapphire crystal maximum weight records, officially put into operation of the project, to fill the gaps in the domestic production of large size sapphire.

Hundred kilograms of sapphire crystal LED project is an important project of Guizhou Province, the development of strategic emerging industries, a total investment of 2 billion 200 million yuan, the first successful trial production four 100 kg level large size sapphire crystal, a maximum of 105 kg, a maximum weight record in asia. 26, hundred kilograms LED sapphire crystal project was officially put into operation in the high-tech industrial zone of Guiyang City, the China became the world's fourth countries with large size sapphire crystal growth and processing technology, is an important symbol of the world into the leading ranks of the sapphire substrate material production.

Sapphire crystal is a very important basic material in modern industry, especially in microelectronics and optoelectronics industry. It belongs to the upstream product of LED new light source industry chain. Sapphire crystal is widely used in many fields such as semiconductor, chemical industry, aviation, aerospace, national defense and so on. Among them, large size sapphire crystal accords with the demands of global market trends, large size sapphire crystal can be made in accordance with the axial diameter of 2 inches, 4 inches, 6 inches of crystal, crystal by cutting, grinding and polishing a sapphire substrate for LED, but also can be used for military purposes.

Guizhou has a wealth of alumina resources to ensure the supply of raw materials for the project.
