High-temperature low-iron sintered mullite researched and developed by our company is formed by processing and grinding high-quality raw materials, pressing, forming, and sintering in a tunnel kiln at the high temperature of more than 1,700℃, and has the performance features of the common M series and unique advantages of lower iron content, purer whiteness (about 80) and more excellent related parameters.

The high-temperature low-iron sintered mullite is one of preferred raw materials for producing high-end and special refractory materials and is applied to daily ceramics, sanitary ceramics, kiln furniture, shed boards and columns, precision casting sand, coatings and so on.
