What is the difference between high-purity alumina powder and α-Al2O3?
1. High-purity aluminum oxide powder boasts excellent activity, high purity, concentrated particle size distribution, and is free of sulfur. It is widely used in high-tech fields such as trichromatic phosphors, YAG single crystals, artificial gems, high-pressure sodium lamps, long-lasting phosphorescent matrix materials, structural ceramics, bio-ceramics, and functional ceramics. High-purity low-sodium α-Al2O3 powder is produced by high-temperature calcination of industrial aluminum oxide, yielding aluminum oxide powder with the A phase. After thorough grinding, it is processed into micro-powders of various fineness. It serves as a polishing agent for ceramics, glass, jade, and other crafts, and is also an important raw material for refractory materials.
