When mentioning alumina ceramics, many people will also think of mullite ceramics. These two products have many similarities, and of course there are many differences. Next, let's analyze the differences between the two products in detail.
Mullite ceramics and alumina ceramics are two different ceramic products, and their connection with floor tiles is also different. Under normal circumstances, floor tiles are not specially made of alumina, mainly because pure alumina ceramics are very Expensive, if used as floor tiles, it will consume a high cost.
The mullite ceramic mentioned here is actually a product produced by the reaction of alumina and silica. Compared with alumina ceramics, it has obvious differences in performance. In terms of hardness, alumina ceramics are harder than mullite ceramics, but both are hard enough that they are not easy to break during use.
In terms of corrosion resistance, although mullite ceramics are acid-resistant, they are not alkali-resistant; while alumina ceramics are first-class in acid and alkali resistance, but for floor tiles, alumina ceramics have too high corrosion resistance. unnecessary. The sintering temperature of mullite ceramics is relatively low, so the cost is low.
It is also compared in terms of thermal shock resistance, and the result is that the thermal shock resistance of mullite ceramics is higher than that of alumina ceramics; similarly, the high temperature creep of mullite ceramics is higher than that of alumina, so Mullite can bear higher weight at high temperature, and alumina ceramics are worse.
