High-alumina bricks are produced on the base of the top quality calcinated fireclay, andalusite, bauxite, aluminium oxide, fused corundum, refractory clays and kaolins.

Two different technological processes – dry and semi-dry pressing are applied for the manufacturing.

This is carried out on computer controlled production lines.

High-alumina bricks are intended for linings of aggregates operating at elevated temperatures in various industrial branches.

  1. AT – high-alumina dense brick 
  2. 80 – Al2O3 content in % 
  3. A – andalusite-based
    B – bauxite-based
    K – corundum-based
    V – high-alumina aggregate-based
  4. C – with addition of Cr2O3
