The main requirements imposed on bearings – homogeneity and wear resistance – can be satisfied only with artificial sapphires, since natural crystals with homoge-neity similar to that of artificial sapphire are hardly ever encountered. Inhomogeneity of the stone leads to elevated wear of friction pairs; therefore, the service life of bearings made with artificial sapphire is longer.
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.
