Ultrafine powder technology is a new technology developed gradually andvigorously in the early1970s, which is applied in many fields of industrialtechnology. After ultrafine grinding, materials will show a lot of excellentperformance. Ultrafine powder has finer granularity, and the surface distributeparticles more uniformly, so it has higher surface activity and surface energy,faster chemical reaction speed, larger adsorption capacity and higher solubility,and has excellent physical property performance suc...
