Zirconia Oxide - silicon carbide | sintered silicon carbide | alumina oxide | fine ceramics | zirconia oxide | pump | pumps | pump ceramics | pumps ceramics

Except inheriting the special characters (high strength, high hardness, thermo-endurable capability, anti-chemicals and high chemical stability) of fine ceramics, zirconia also owns better tenacity than ordinary ceramic materials, which enable zirconia to be applied in many industries, such as the production of spindle seals and bearings, cutting tools, molds, and vehicle parts, etc.; it also can be applied for medical applications, such as being the artificial hip joints of human body and similar.
Zirconia material can be categorized into the following four sorts:

1. Fully stabilized zirconia (FSZ)

Formed by complete cubic lattices structure; poor in mechanical properties.

2. Zirconia toughened ceramics (ZTC)

Compound of the 2nd phase and other materials (Al2O3, Si3N4 and glass, etc.); the tenacity and mechanical properties are improved.

3. Partially stabilized zirconia (PSZ)

PSZ is the sort of zirconia material we are producing now; PSZ is made by adding Y2O3 into the zirconia structure base that will make the square lattice phase distributed in the cubic lattice phase; through the phase-change of square lattice phase, the zirconia organization would obtain higher tenacity and thus toughen the PSZ property.

4. Tetragonal zirconia polycrystals (TZP)

TZP is made by adding Y2O3-ZrO2 into the zirconia base, which can get better mechanical properties, higher strength, tenacity and chemical stability; it is widely applied in structure and medical applications.
