As energy-saving materials, thermal insulation materials are essential in high-temperature kilns.

At present, the insulation and refractory materials industry has increasingly higher requirements for efficient and low-cost products. The advantages of corundum refractory materials are becoming more and more important. At the same time, corundum composite insulation and refractory materials have also attracted people's attention and developed rapidly.

Corundum composite refractory materials, in addition to corundum, also have a second component, whose purpose is to improve the thermal shock stability, slag resistance and other properties of the product. The second component of this multi-phase material is generally mullite, which can be pre-synthesized mullite, or elemental silicon, silicon oxide or minerals containing silicon elements can be added to the ingredients.

Therefore, corundum-mullite insulation material, as such a corundum composite insulation refractory material, has broad application prospects, and due to its light weight, good high-temperature insulation performance, good thermal stability and other excellent properties, it is widely used in refractory materials. The field is widely welcomed.
