The alumina-silica (SiO2) group of refractories includes alumina (Al2O3) refractories, which correspond to the SiO2 -Al2O3 phase equilibrium system. They differ from fire clay refractories in terms of Al2O3 content, with Al2O3 levels typically exceeding 45 percent. These refractories have a different raw material base than fire clay bricks. Because of their outstanding slag resistance and mechanical qualities, alumina-magnesia and alumina-spinel castables have been broadly ap

Refractory Fibre Products Refractory Fibre Products Ceramic fibers are small-diameter filaments or threads made of ceramic materials, most often alumina and silica, that are employed in lightweight units for electrical, thermal, and acoustic insulation. To maximize the strength, abrasion resistance, and insulating qualities of your application, refractory compounds are frequently utilized in conjunction with monolithic forms. The products benefit from refractory products’ str
