Product Description

Calcined and reactive aluminas for refractories

calcined alumina for refractories

Due to the excellent high temperature properties of -Alumina, Calcined Aluminas are used in many refractory
applications, both in monolithic and shaped products.

Reactive alumina for refractories

The fully ground reactive aluminas are specially designed for the production of high performance refractories,

where defined particle packing, rheology and consistent placement characteristics are as important as superior physical properties of the final product.
