Why is alumina ceramic tiles resistant to acid and alkali corrosion?
The main material of our wear-resistant ceramics tiles is alumina. After calcination at a high temperature above 1300 degrees, the alumina will be transformed into α-type alumina in the form of atomic crystals. In the crystal lattice of α-type alumina, oxygen ions are hexagonally densely packed, and aluminum ions are symmetrically distributed in the octahedral coordination center surrounded by oxygen ions. The lattice energy is very large, so the melting point and boiling point are very high. And it shows obvious chemical inertness, it is difficult to react with acid and alkali.
Wear-resistant alumina ceramic tiles are pasted with high-quality inorganic adhesives, which are also very resistant to acid and alkali corrosion. The combination of the two forms a super-strong acid and alkali corrosion resistance of wear-resistant ceramics.
