The LED substrate sapphire wafer manufacturer successfully produced more than 170 kilograms of sapphire crystals, setting a record for the maximum weight of a single LED sapphire crystal in Asia. The formal commissioning of the project filled the gap in domestic large-scale sapphire crystal batch production.
The 100-kilogram LED sapphire crystal project is an important project for the development of strategic emerging industries, with a total investment of 2.2 billion yuan. The first batch of trial production of four 100-kilogram large-size sapphire crystals, the largest one being 170 kilograms, set a record for the largest weight in Asia. On the 26th, the 100-kilogram LED sapphire crystal project was formally put into production in the high-tech industrial zone, making China the fourth country in the world to have large-sized sapphire crystal growth processing technology, and an important sign to enter the world's leading rank of sapphire substrate production .
Sapphire crystal is a very important basic material in modern industry, especially in microelectronics and optoelectronics industries. It is an upstream product in the new LED light source industry chain. Sapphire crystals are widely used in high-tech fields such as semiconductors, chemicals, aviation, aerospace, and defense. Among them, large-size sapphire crystals are particularly in line with the global market demand trend. Large-size sapphire crystals can be manufactured into 2 ", 4" and 6 "diameter rods in accordance with the crystal axis. The sapphire substrate can also be used for military applications.
