Calcined Aluminas

Calcined aluminas are commonly used in the manufacture of refractory materials, glass and enamel, ceramic tiles and ceramics, and electronic ceramics. 

CAS No.: 1344-28-1

EINECS NO:215-691-6

Chemical Formula  :Al2O3

Content:98.0-99.8%

Mohs’ Hardness :9

Bulk Specific Gravity :3.7-3.9%

Melting Temperature:2040℃

Place of Origin: Shandong, China

Appearance:White Crystalline Powder

Character: Calcined aluminas are made by firing alumina raw materials at different temperatures, which depends on the calcining technology of alumina, and firing alumina raw materials into alpha alumina to make it become the densest and most stable form. The alumina particles after calcining are in the shape of crystal clusters. The higher the calcining degree is, the larger the particles will be.

Packaging:25kg PP bag(Special packaging on request)

Features

  •  High heat capacity
  •  High resistivity
  •  Chemical inertness
  •  High fire resistance
  •  Abrasion resistance
  •  High thermal conductivity

Applications

Due to the excellent high temperature properties of α-Alumina, Calcined aluminas are commonly used in the manufacture of refractory materials, glass and enamel, ceramic tiles and ceramics, and electronic ceramics.
