Product Description

Sintered Mullite is a high-quality refractory raw material produced by selecting and homogenizing high-alumina bauxite, industrial alumina, and high-quality silica, followed by solid-state reaction sintering at temperatures above 1750℃. Its characteristics include well-developed fine, interlocking microcrystalline structure with high primary crystalline phase content, featuring high refractoriness (up to 1790℃ and above), low thermal expansion coefficient, excellent thermal shock resistance, strong chemical corrosion resistance, and low high-temperature creep value.
