3.95g/cm3 Proportion Calcined Alumina The Top Choice for Industrial Alumina Needs
Calcined alumina, also known as aluminum oxide calcined, is a high purity and fine particle size powder made from low sodium calcined alumina powder through grinding and deep processing.
The calcination process of alumina removes impurities and moisture, resulting in a high purity product. It also produces a fine particle size, which allows for better dispersion and coverage in various applications.
Due to its high hardness and density, calcined alumina is widely used as a refractory material in high temperature environments. It is also used as an abrasive material in polishing and grinding applications.
