| Details : |
Block-shaped alumina (RTM-6) is fabricated by compression of the superhigh pure alumina powder of our company with the characters of high density (density >3.3g/cm3),high purity etc. The product can be used to manufacture sapphire, so that the crucible volume can be completely used. The product has already replaced the similar products abroad and been widely used in manufacturing of sapphire, laser crystal (YAG), artificial gem and so on.
