Product Introduction
Sintered Mullite is a high-quality refractory raw material and the only stable binary compound in the Al₂O₃ - SiO₂ system. It exhibits a Mohs hardness of 6-7 and excellent fire resistance up to 1800 ℃. Sintered Mullite is produced through a wet homogenization process and subsequent high-temperature calcination. Its alumina content varies between 45% and 75%, with main variants including M45, M60, and M70 sintered 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.
