CS-4 Alumina-Zirconia-Silica

CS-4 Alumina-Zirconia-Silica
August 18, 2016 Monofrax

Monofrax® CS-4 is the intermediate chemistry (36% ZrO2) of the three Monofrax AZS compositions. Monofrax CS-4 has the best thermal shock resistance of all AZS materials. This material’s properties, performance and cost are a compromise between CS-3 and CS-5. Superior resistance to high temperature corrosion by molten slags and glasses, structural stability, and high abrasion resistance result from the intergrowth of the zirconia and alumina crystalline phases and low open porosity.
