Zirconia (ZrO2 & Zirconium Oxide) is a unique advanced ceramic. Products manufactured from zirconia ceramic exhibit superior mechanical properties such as high strength and flexibility. Heat insulating properties and oxygen-ion conductivity indicate zirconia has potential for use in a wide variety of applications - everything from telecommunications to the new energy of the future and environmentally beneficial products.
Depending on doping material different material properties could be achieved because of influencing the Yttria's microstructure. The "Ceramic Steel" titled Zirconia is doped with Yttria forming an ultra-fine ductile structure with sub-micron grain formation leading to enormous bending strengths. Magnesia doped qualities are less strong also showing a coarser microstructure.
Advantages:
1). Excellent insulation, security, long working life.
2). High temperature resistance
3). Resistance to electric breakdown
4). Stand wear and tear
5). High strength
6). Corrosion resistance
7). Good compactness
8). High hardness
