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.
