Product Introduction
Fused mullite is a high-quality refractory raw material and the only stable binary compound in the Al₂O₃ - SiO₂ system. It possesses a Mohs hardness of 6-7 and excellent fire resistance up to 1800 ℃. Fused mullite is produced by melting high-quality raw materials at high temperatures using an industrial electric furnace. Its alumina content varies between 60% and 75%, with the main variant being DM70 fused mullite.
Product Characteristics
● High fire resistance;
● Uniform expansion and good thermal shock stability;
● High load softening point and low high-temperature creep value;
● High hardness and good resistance to chemical corrosion.
