Alumina - Calcined

What is it?

Calcined alumina is manufactured through further calcination of alumina to remove impurities. The calcination process results in either a chemical grade alumina (KA13) or a smelter grade alumina (KA01).

  • KA13 is a coarse product, with low chemical impurities. It has a medium surface area and a fine primary crystal size.
  • KA01 has a high surface area and low chemical impurities. The product is a sandy, coarse alumina with normal soda.

Where is it applied?

KA13 is typically used in:

  • Fused Alumina
  • Tabular Alumina

KA01 can be used for:

  • Glass making
  • Thermal insulation wool
  • Traditional ceramics
