Description
Specifications

The combination of these properties renders Zirconium dioxide ceramics irreplaceable for numerous industries (from high resistive parts to medicine).


Zirconium dioxide is used to obtain extra heat resistive products, heat resistive enamel, refractory glass, different types of ceramics, ceramic pigments, thermal protective coatings, catalyzers, cutters and abrasive materials. Recently zirconium dioxide is widely used in fiber optics and production of ceramics to be integrated in electronic devices.


Zirconium dioxide (ZrO2) has a unique set of properties, such as:

  • High hardness
  • Perfect corrosion resistance
  • Low thermal conductivity
  • Crack resistance
  • Robustness at high temperatures

Characteristics:

  • Maintain robustness at high temperatures (melting point 2715 °С);
  • High hardness;
  • Corrosion resistance;
  • Low thermal conductivity.

Application:

  • Facing for worn-off hardware;
  • Roll bearings;
  • Grinding bodies;
  • Crucibles;
  • Screw conveyors;
  • Elements of valves and shut-offs;
  • Rolls for milling fittings;
  • Elements for oxygen sensors;
  • Heaters;
  • Heat-resistive products;
  • Plungers;
  • Ceramic insulators.

We supply zirconium dioxide products of different design per Customer’s individual drawings.
