Silica Mullite Bricks

Silica mullite bricks feature high cold crushing strength, high high-temperature structural strength, good thermal shock resistance, good wear resistance, and strong anti-spalling properties. During use, a protective layer is continuously formed to resist the penetration of harmful substances such as alkalis and sulfur, providing excellent corrosion resistance. They are mainly used in cement kilns or kilns with high requirements for thermal shock and wear resistance.
