Customizable Size Sapphire Crystal

There are two classes of modern articles made of sapphire: constructional and functional. Constructional sapphire is used for the creation of products with high mechanical stability. Functional sapphire has a specific structure and electrical, optical, and thermal properties. This classification is arbitrary, as this material is multifunctional, and sapphire articles (such as rocket nose cones) often combine the two functions. Constructional and functional sapphires are comparatively new materials, so the scale of their production compares unfavorably with that of tradi-tional materials. At the same time, the rate of growth in their production far exceeds that of steel, aluminum, and some other materials.

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.
