Black zirconia is a material with special properties and great applications. It is made of zirconium oxide (ZrO2), which is given a black appearance by the addition of specific additives and a special process.

Black zirconia ceramic structural components have the highest fracture toughness, and they have excellent mechanical properties, including high strength, fracture toughness, wear resistance, good thermal shock resistance and low thermal conductivity.

There are several types of zirconia ceramics, with the most common ones being yttrium oxide partially stabilized zirconia (Y-PSZ) and magnesium oxide partially stabilized zirconia (Mg-PSZ). These ceramics possess unique resistance to crack propagation and high thermal expansion, making them highly suitable for joining ceramics to metals like steel.

Mg-stabilized zirconia, known for its exceptional wear and corrosion resistance, finds application in valves, pumps, and gaskets. It is the preferred material in the chemical processing and petrochemical industries.

Zirconia ceramic products are versatile and find application in various industries, including:

  • Precision shafts in high-wear environments

  • Refractory materials

  • Bushings and caps

  • Fiber optic rings and sleeves

  • Cutters and blades

  • Fuel cell parts

  • Bearings and rollers

  • Electrical insulators

  • Oxygen sensors

  • Medical components

  • Mechanical seal components

  • Pumps, pistons, and cylinder liners.
