Alumina ceramic is the most mature of the engineering ceramics, offering excellent electrical insulation properties together with high hardness and good wear resistance,but relatively low strength and fracture toughness.Alumina ceramics are generally white but may also be pink or ivory.The color is derived from either the sintering additives or impurities in the raw materials.

The excellent advance ceramic propeties:

· Flexural strength	· Chemical resistance	· Electrical insulation	· Corrosion resistance	· Dielectric strength
· Wear resistance	· Temperature resistance	· Thermal conductivity	· High voltage	· Hardness...
