Bauxite

Description

Alpha Star is a homogeneous calcined high alumina aggregate. 
Specially selected high purity ores are custom processed and calcined to obtain a dense, volume stable aggregate with low apparent porosity.
The combination of lower impurities and unique processing results in a consistent high quality aggregate.

Alpha Star is an ideal aggregate to resist abrasion and hot metal erosion in blast furnace troughs and ladles.
Its consistent physical and chemical properties make it ideally suited for low cement, ultra low cement castable and plastic refractory applications.
