Product Description


At present, most natural gems are subjected to procedures of color ennoblement after which their value increases by 1–2 orders. As a rule, improvement of aesthetic and decorative quality in gems is a result of either the formation of color centers, which have not been realized under natural conditions due to certain causes or sup-plements to such processes. The color of sapphire can be changed either within the whole of the crystal or in its surface layer. The crystals from different deposits are distinguished by variable combinations of impurities and specific effects.




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.
