Xinhui Grade 28 lightweight mullite brick uses high-purity refractory powders as the base material. It is formulated to a 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 support, suitable for kiln insulation and lining locations that require higher energy efficiency and high-temperature stability.

Product Description:

Xinhui Grade 28 lightweight mullite brick uses a high-purity raw material system to improve chemical stability and corrosion resistance. With a uniform pore structure and strict dimensional control, brick laying is smoother and on-site cutting is more convenient. It can be used for hot-face or semi-hot-face high-temperature service conditions.

Product Features:

• Low heat capacity and low thermal conductivity, reducing furnace heat storage loss for stable energy savings
• High purity and low impurities for more reliable corrosion resistance
• High temperature resistance with direct flame contact
• High strength and excellent high-temperature volume stability, not easy to deform
• Accurate dimensions, supports any cutting and machining for higher construction efficiency
