  • Almatis :: Calcined Aluminas

    Calcined aluminas have a particle size similar to ground mineral aggregates and can therefore easily replace aggregates with lower purity. By increasing the overall alumina content of the mixes and improving their particle packing through the addition of fine alumina, the refractoriness and mechanical properties, such as hot modulus of rupture and abrasion resistance, are improved.
