Fused Mullite

Fused Mullite is produced by fusing alumina and silica in precise ratios under high temperatures in electric arc furnaces. This process yields a crystal structure with excellent dimensional stability, low creep at high temperatures, and superior thermal shock resistance. Fused Mullite is a preferred material in applications such as kiln furniture, investment casting molds, and insulation bricks, especially in industries like ceramics, metallurgy, and petrochemicals. Its high refractoriness and resistance to chemical corrosion ensure reliable performance in both shaped and unshaped refractory systems exposed to frequent heating and cooling cycles.
