Advantages
Alumina ceramics have a high melting point and high boiling point and can be used at high temperatures.
Alumina ceramics are chemically inert and can be used under the conditions of most strong acids, strong alkalis, inorganic organic salts, etc.
Because the product material is non-magnetic and not easy to stick to the dust, it can reduce the product surface flaking.
Insulator at room temperature, high resistivity, can be used in equipment requiring insulation.
Applications
Electrical industry
Electric heating industry
Electronics industry
Automotive industry
Petrochemical industry
Metallurgical industry
