Zirconia Ceramic Components

(ZrO2)

Zirconia ceramics is the strongest and toughest material among advanced ceramics.

Zirconia (ZrO2) has a monoclinic crystal structure at room temperatures, but transforms
to cubic and tetragonal structures at elevated temperatures. This transition can result in
the development of stresses during cooling which negatively impact the strength of the material.

Type of Zirconia Ceramics:

1. Properties of Yttria Stabilized Zirconia ceramics: The working temperature is up to 2100 ℃; high density, low thermal conductivity; chemically inert; anti-metal melting; ion conductivity; wear resistance, high hardness, high fracture toughness;

2. Properties of Cerium Stabilized Zirconia ceramics: The working temperature is up to 2100 ℃; high density, low thermal conductivity; chemically inert; resistance to metal melting; wear resistance, high hardness, high fracture toughness;

3. Properties of Magnesium Stabilized Zirconia ceramics: The working temperature is up to 2400 ℃; high density, low thermal conductivity; chemically inert; resistance to metal melting; wear resistance, high hardness, high fracture toughness.

Typical Physical Properties of Zirconia Ceramics:

1.High hardness, high toughness, high bending strength, zirconia ceramic density is 5.95-6.05g/cm3, zirconia ceramic toughness is 8MPa · m1/2 or more higher;

2.High wear resistance, low friction coefficient, wear resistance is 15 times that of alumina ceramics, friction coefficient is only 1/2 of that of alumina ceramics, after grinding(polishing) processing, the surface finish is better, up to ▽9, mirror surface, extremely smooth, with a lower coefficient of friction;

3.Good insulation, corrosion resistance, no static electricity, high temperature resistance, excellent thermal insulation, thermal expansion coefficient is close to that of steel;

4. Zirconia ceramics have self-lubrication, can solve the pollution caused by the lubricating medium and inconvenience caused by feeding.
