What Is The Difference Between Alumina Ceramics And Mullite Ceramics？

 

Mullite ceramics and alumina ceramics are two different ceramic products. Under normal circumstances, floor tiles do not specifically use alumina. This is mainly because pure alumina ceramics are very expensive, and using them as floor tiles will consume high costs.

Mullite ceramics are actually a product produced by the reaction of alumina and silicon oxide. There are obvious differences in performance compared with alumina ceramics. In terms of hardness, al2o3 ceramics are harder than them. However, both are hard enough to be not easy to break during use.

 

In terms of corrosion resistance, mullites are acid-resistant but not alkali-resistant. However, the acid and alkali resistance of alumina ceramics is first-class. For floor tiles, the corrosion resistance of al2o3 ceramics is too high and unnecessary. The sintering temperature is relatively low, lowering the cost.

The advantages of mullite ceramics:

The result is that the thermal shock resistance is higher than that of alumina ceramics. Similarly, the high temperature creepability is higher than that of alumina, allowing mullite to withstand higher weights at high temperatures. In contrast, alumina ceramics are worse.

In addition, the difference between alumina ceramics and mullite ceramics is also reflected in the resistance. It is obvious that the resistance of alumina ceramics is higher than that of mullite ceramics. This is the main reason for choosing alumina ceramics as a high-voltage insulator material.
