Zirconia (TZP) Zirconia ceramics have a martensite-type transformation mechanism of stress induction, giving the ability to absorb great amounts.
Zirconia ceramics have a martensite-type transformation mechanism of stress induction, giving the ability to absorb great amounts of stress relative to other ceramic materials. It exhibits the highest mechanical strength and toughness at room temperature. Zirconia has excellent wear, chemical and corrosion resistance and low thermal conductivity.
Common applications include extrusion dies, wire and pipe extension, guide and other wear rollers, pressure valves, and bearing materials.
