Alumina is one of the most important materials in manufacturing of refractories and insulators. Insuatries including steel, copper, lead, zinc, ferrous, and non-ferrous alloys, glass and ceramics, cement, lime and dolomite, thermal power plants, chemical and petrochemical industries, and recycling industries are among consumers of such refractories and insulators.
Different types of refractories and insulators containing high properties of alumina are produced, in different varieties including:
- Light weight insulating bricks
- Refractory bricks
- Refractory castables
- Ceramic boards, z-blocks and blankets
