Alpha alumina has stable crystal form, simple purity control, narrow range of particle size distribution, and lower ratio than the surface; gamma alumina particle size is difficult to make large, and its specific surface area is large. When it is heated to 1200 degrees, it will be converted into alpha alumina.
Application: Alpha alumina is used in refractories, flame retardants, grinding machines, fillers, large scale integrated circuit boards, etc.; gamma alumina can be used as an adsorbent, catalyst, catalyst carrier, desiccant, etc.
The catalytic function of nano-alumina is one of the most important in its new applications. The specific surface of nano-sized powders is very large, so there are abundant mismatch bonds and hypoxic bonds on the surface of particles. When pressed into thin sheets, the nano-sized powders contain abundant voids, which can be used to prepare porous films with high surface activity. The performance of the catalysts and catalyst carriers made from the nano-sized powders is several times better than that of the similar products currently used.
Alpha alumina nanopowder is added to the coating to provide excellent abrasion and scratch resistance. Packaging & Shipping Package: double anti-static bags, drums. 1kg/bag, 25kg/drum. Shipping: Fedex, TNT, UPS, EMS, DHL, Special lines, etc. Our Services
