Mullite Castable Production - Xinhongji Refractory
Mullite castable refractories are high-performance materials widely used in high-temperature industrial applications due to their excellent thermal stability, mechanical strength, and corrosion resistance. Composed primarily of synthetic mullite (3Al₂O₃·2SiO₂), these castables exhibit low thermal expansion, superior thermal shock resistance, and prolonged service life in extreme environments. They are commonly applied in furnaces, kilns, incinerators, and boilers, particularly in the steel, cement, and petrochemical industries. Mullite castables offer easy installation through casting or gunning techniques, ensuring dense, crack-free linings after curing and firing. Their high alumina content enhances refractoriness (up to 1800°C), while additives like silica fume or microsilica improve workability and sintering properties. With tailored compositions, they balance cost-efficiency and durability, making them ideal for demanding thermal processes. 🔥 Hot sale! Mullite Castables 📣 Contac...
