Technical Description of al2o3 powder
The product has high purity, small particle size, uniform distribution, large specific surface area, high surface activity, low loose packing density, and gas phase method, which overcomes the shortcomings of hard agglomeration, difficult dispersion and low purity of particles prepared by wet chemical method on the market.
There are a large number of unsaturated residual bonds and hydroxyl groups in different bond states on the surface, which deviate from the stable silicon oxygen structure due to the lack of oxygen on the surface, so it has high reactivity. The loose density of the powder is relatively small, and it is easy to disperse.
Application of alpha alumina powder
Nano aluminum oxide crystal phase stability, high hardness, good dimensional stability, can be used to strengthen and toughen all kinds of plastic, rubber, ceramic products, especially to improve the density of ceramic, finish, cold and hot fatigue, fracture toughness, creep resistance and wear resistance of polymer material products. Because nano aluminum oxide is also a far-infrared emission material with excellent performance, as far-infrared emission and insulation material is used in chemical fiber products and high pressure sodium lamp. In addition, α phase alumina has high resistivity and good insulation performance, which can be used in the main parts of YGA laser crystal and integrated circuit board.
The company can carry out targeted surface treatment package, so that nano alumina powder can be stably dispersed in the solvent system, the formation of transparent or translucent sol, applied in coatings, glass surface, electronic packaging, etc.
