Zircon Mullite Bricks Introduction
Zircon mullite refractory brick is made of high-quality mullite sand and zircon powder as the main material, zircon mullite bricks are produced by the production process of the molding at high temperatures and sintered at high temperatures. Zircon-mullite brick has the characteristics of high bulk density, high strength, good thermal shock resistance, high-temperature erosion resistance, and good slag resistance.
Zircon Mullite Bricks Properties
- High strength
- Good thermal shock resistance
- High-temperature erosion resistance
