Advantages of zirconia parts:
·High wear, heat, pressure, and chemical attack resistance (gas and liquids)
·Extreme hardness
·Excellent electrical insulation
·Relatively lightweight
Application:
Because zirconia has good properties of elasticity module and high hardness, as well as the above good properties, the parts made from zirconia are often used as mechanical or pump seal plate or disc.
