Monofrax®
M Alpha-Beta Alumina

Monofrax® M is a fusion-cast alumina refractory containing approximately 40% alpha alumina, 60% beta alumina, and a minor amount of crystalline silicate boundary phase. Invented in the 1940’s, Monofrax M has been successfully used in a wide range of applications in both glass and non-glass industries. It offers excellent corrosion resistance and low defect potential in the conditioning or refining end of a glass melting furnace. Monofrax M is selected for use in metal reduction cells due to its corrosion resistance and in skid rails in steel mills due to its excellent abrasion resistance. Since the mid-1990’s it is the primary solution for crowns and superstructure in oxy-fuel glass melting furnaces.
