Alumina ceramics have good acid and alkali resistance and can be used under medium or strong alkali conditions under normal conditions.
Alumina ceramics are not resistant to high-strength acids and bases.
If the use of the environment is beyond the 1:9 concentration of hydro-chloric acid, or more than 10% concentration of sodium hydroxide solution, there will be more obvious corrosion.
Alumina ceramics have characteristics such as wear resistance, high temperature resistance, acid and alkali resistance, insulation, etc., and are therefore widely used in many industries such as machinery, electronics, chemical engineering, and fireproofing. refractory.
