Alumina-Magnesia-Chromite Spinel Castable
Alumina-magnesia-chromite spinel castable is made from fused/sintered alumina-magnesia-chromite spinel and high-alumina aggregates as the main raw materials, bonded by a low-cement or chemical bonding system; the main crystalline phases are magnesia-alumina spinel and chromite spinel.
