What are Engineering Ceramics?

Engineering ceramics are those which have been specially produced to create ceramic

components to providesolutionsfor engineering conditions with specialist requirements.

The thermal stability, wear-resistance andresistance to corrosionof ceramic components

make the application of ceramic the ideal choice for manyindustrial areas.Ceramic

componentscan provide considerable lifetime increases over conventional metalcomponents.

If you are looking for a material,that has alonger working life and can stand up towear,

corrosionand high temperature,the engineering ceramic is the answer.

Alumina Ceramic

Alumina ceramic is the most mature of the engineering ceramics, offering excellent electrical

insulation properties togetherwith high hardness and good wear resistance,but relatively low

strength and fracture toughness.Alumina ceramics aregenerally white but may also be pink or

ivory.The color is derived from either the sintering additives or impurities in theraw materials.

Features &Advantages

1. High hardness.

2. High heat resistance : Alumina ceramic has execellent themal stability,which means that it is

widely used inareas 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.
