Product Description
At present, the greater part of artificial sapphire is used as a functional material. However, extremely high production rates are predicted for constructional sapphire as well. This follows from estimations made by specialists in the world’s leading firms. According to the performed analysis, in 70% of cases future prospects for the use of sapphire are tied to its mechanical, thermal, and chemical properties.
Although there are lots substrates which are regarded as potential materials to replace sapphire substrate, it is still dominated in the substrates (for GaN LED growth) market, because of its reasonable price and relatively low mismatch. Zhongju is capable of processing substrates according to customer needs. Currently, our sapphire substrate productions ranges from 2 to 12 inches with high quality and accurate orientation.
