Product Description

The particle size of JLW ultra fine alumina powder is 0.2-1µm, the purity can reach 99.9%, 99.99%, 99.999%, the particle size and purity can be customized according to specific needs.

Ultra fine alumina micro powder has high purity, narrow particle size distribution, small primary grain size, high a-phase transformation rate, and a morphology resembling spherical shape.

Ultra fine alumina powder can be used in artificial crystal, ceramics , polishing, diaphragm coating,anode and cathode materials, spraying materials, etc.

JLW has a strict quality control system, including newly purchased American Cantata surface area, pore volume analyzer, spectrophotometer, flame photometer and other testing equipment, to ensure product quality. JLW is long-term partner of Sinopec, PetroChina, CPC (Changding), Shenyang Petrochemical, and others.
