Near-spherical α-alumina is a proprietary product of our company, made from high-quality alumina raw materials from Guangxi Province through high-temperature calcination and modification. It features a near-spherical, dense, single-crystal structure, good dispersibility, narrow particle size distribution, small specific surface area, high purity, low oil absorption, and low viscosity. The pH value is 7-8, and the original crystal size is 5-7 μm. It is mainly used in electronic device thermal conductive fillers, inorganic membrane filtration ceramics, and refractory materials.
