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.Zirconia  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 : Zirconia ceramic has execellent themal stability,which means that it is

widely used in areas where resistance to high temperatures is essential.

3. Good wear resistance : Zirconia  ceramic is the material of choice for  wear parts.

4. High electrical resistivity : Zirconia 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 zirconia leads to high corrosion resistance.

Zirconia ceramic has the advantages of high glossiness, high heat resistance, good smoothness, good corrosion resistance, high wear-resisting, high intensity, precision process, polishing surface and so on. It widely used in a variety of mechanical equipments.
 

Unlike other ceramic materials, zirconia is a material with very high resistance to crack propagation. And its fine grain size enables excellent surface finishes and the ability to hold a sharp edge.

ZrO2 ceramics are used among other applications, as mobile phone shell, as zirconia diamonds, as materials for crowns and bridges in the dental industry, as insulating rings in thermal processes, and as oxygen measurement cells in lambda probes.
