Alumina wear-resistant ceramic product is a new ceramic chemical material with low wear, high specific gravity and high hardness. It is mainly made of aluminum oxide (AL2O3) and sintered at a high temperature of 1700°C.
Alumina ceramic products are suitable for use in mechanical equipment that needs protection from abrasion, as well as in systems for material delivery, pulverizing, ash or dust cleaning in thermal power production. They are also suitable for various high-voltage and high-current applications.
