Product Description

The purity of high purity alumina powder can reach 99.9%, 99.99%, 99.999%, the particle size and purity can be customized according to specific needs.

High purity alumina powder is white micro powder with uniform particle size, easy dispersion, stable chemical properties, moderate high-temperature shrinkage performance, good sintering performance, high conversion rate, and low sodium content. This product is the basic raw material for producing heat-resistant, wear-resistant, and corrosion-resistant products, such as high alumina refractory materials, high-strength ceramic products, automotive spark plugs, advanced grinding materials, etc. 

It is widely used for LED used sapphire crystal raw materials, tricolor phosphors, long afterglow phosphors, high-pressure sodium lamps, glass additives, electronic ceramics, fine ceramics, grinding and polishing materials, catalyst carriers and other fields.

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.
