Zirconia 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.
1. High hardness.
2. High heat resistance : Alumina ceramic has excellent thermal stability,which means that it is
widely used in areas where resistance to high temperatures is essential.
3. Good wear resistance : Alumina ceramic is the material of choice for alumina wear parts.
4. High electrical resistivity : Alumina is an electrically insulating material.
5. High corrosion resistance : It is insoluble in water and only slightly soluble in strong acid and
alkaline solutions. Good chemical stability of alumina leads to high corrosion resistance.
