Xinhui Grade 23 lightweight mullite brick uses high-purity refractory powders as the base material. It is formulated to the target bulk density and produced with organic composite pore-forming materials, vacuum extrusion forming, high-temperature sintering, and precision machining. The product combines lightweight insulation with structural strength and is suitable for high-temperature linings and insulation applications.

• Low heat capacity and low thermal conductivity: faster heat-up, lower furnace heat storage loss, and more stable energy savings
• High purity and low impurities: better chemical stability and more reliable corrosion resistance
• High temperature resistance with direct flame contact: suitable for hot-face or semi-hot-face conditions
• High strength with excellent volume stability: less deformation at high temperature for safer long-term operation
• Accurate dimensions and good machinability: easy cutting and more efficient on-site brick laying

Insulation linings, insulation layers, furnace walls, and furnace roofs in various industrial kilns and thermal equipment where lightweight insulation and stable performance are required.
