sapphire
Synthetic single-crystal sapphire wafers (substrates) or sapphire windows can be used for fused- silica(quartz glass) wafers or windows in the semiconductor industry, owing to their high thermal resistance (over 2000 degrees cercius) and their good optical transmission for wavelengths from IR to UV ranges. Sapphire has high Mohs hardness -- comparable to diamond -- so not so many companies can polish sapphire single crystals with surface quality as precise as for glass or fused silica, especially for large wafers used in electronic and semiconductor industry. We have much experience in polishing large-sized sapphire wafers and windows, as well as sapphire made tubes, prisms, domes, special thin wafers, and other shapes.
