Alumina insulation bricks. The product has high refractoriness and good thermal shock resistance, and is often used as a high temperature insulation layer for kiln. The use temperature is 1350~1500°C, and the use temperature of high-purity products can reach 1650~1800°C. Insulating refractory products mainly made of fused corundum, sintered alumina and industrial alumina.

Lightweight mullite brick. Insulating refractory products made of mullite as the main raw material. The mullite heat-insulating brick is resistant to high temperature, high strength, low thermal conductivity and can directly contact the flame, and is suitable for the lining of various industrial furnaces.

Alumina hollow ball bricks. Alumina hollow ball bricks are mainly used for long-term use below 1800 °C. It also has good chemical stability and corrosion resistance at high temperatures. Compared with other lightweight thermal insulation bricks, alumina hollow ball bricks have high safe use temperature, high strength and low thermal conductivity. The bulk density is also 50% to 60% lower than that of dense products of the same composition, and can withstand the impact of high temperature flames.
