Magnesia Partially Stabilized Zirconia
Description
Reviews
Compared to other advanced ceramics, Zirconia ceramics have high melting point, low thermal conductivity, high hardness, low friction, chemical inert and excellent electrical property (insulation and electric conductivity). Due to these characteristics, Zirconia is utilized to manufacture zirconia plunger piston, flange, pins, sensors, crucible, grinding medium, optical fiber, watches, teeth, cutting tool and so on.
● 8 to 12 mol % Magnesium stabled Zirconia is named magnesia partially stabilized Zirconia(Mg-PSZ). Mg-PSZ have excellent high temperature performance and thermal shock resistance, its working temperature can be higher than 2000℃. Mg-PSZ is usually applied to Metallurgy, Steel Industry, Petrochemical Industry, Mechanical sealing rings, Standard Measuring Tools, etc.
