High-Alumina Bricks

P-D Refractories manufactures high-alumina bricks with an Al₂O₃ content range of 45 % to about 99 % and based on natural raw material sources and synthetic raw materials such as:
  • Fused alumina and sintered corundum
  • Fused mullite and sintered mullite
  • Andalusite and kyanite
  • Bauxite
  • Calcinated fireclay
These products are also offered in combination with raw materials rich in aluminium with either ceramic binding or aluminium phospate binding. Special characteristics of the aluminium rich products, such as thermal shock resistance and corrosion resistance, are achieved by additives having zirconium, chromium and carbon content and which are tuned to the relevant usage conditions.
