Calcined Alumina Powder

calcined alumina micropowder

Calcined alumina micropowder is produced from high-quality industrial alumina as raw material, carefully calcined at controlled temperatures to form stable α-alumina crystalline phases. This process ensures high purity, excellent particle stability, and consistent physical properties. Products made with calcined alumina micropowder as a raw material exhibit outstanding mechanical strength, high hardness, excellent electrical resistivity, and superior thermal conductivity.
