Calcined Alumina Powder 99.5% For Heat-Resistance And Corrosion-Resistance Products
1. Calcined Alumina Powder Introduction
Taking the superior industrial alumina as raw material, Calcined Alumina is produced through the method of advanced high temperature down draught kiln with scientific calcine. These make sure it has the advantages as follows: less trash, high transfer rate, stable contraction, and great variety of goods. The shape is fine sand or powdery with white color, As its equal particle sizes and dispersing easily, it has a good sinterability. Calcined Alumina is the basic raw material for heat-resistance and corrosion-resistance products, such as high-alumina refractory, high level ceramic products, car used sparking plug, electronic ceramic parts, material for iron and steel oven, high temperature friction material and polishing grinding products, ect.
