  • zirconia frac plug button

    ZrO2 Zirconia Ceramic Frac Plug Buttons

    Zirconium dioxide, also known as zirconia and zirconium oxide, is a crystalline metal oxide that has found its way into the technical advanced ceramics industry. It is characterised by its high thermal resistivity, mechanical resistance, and abrasive properties.

  • Alumina Ceramics

    Alumina Ceramic Piston for High Pressure Washer Pump

    The ceramic pistons are made using the advanced aluminum oxide ceramic material that possesses high hardness, wear resistance, high temperature resistance, and corrosion resistance, ensuring consistent material performance.

  • boron nitride chamber

    Boron Nitride Plasma Chambers for Hall Effect Thrusters

    One common application for boron nitride is channels used in Hall-effect thrusters for satellites. A hall effect thruster combines an electric field with a magnetic field to ionize a gas flow to generate plasma. The electric field inside an annular channel accelerates the ions in the plasma to very high exhaust velocities.

  • boron nitride crucible

    BN Boron Nitride Crucible Liner

    Crucibles made of BN Boron Nitride are not wetted by molten metal liquids and can be used at temperature up to 2,000 degree C. BN ceramic crucibles own outstanding thermal shock resistance and are also non-electrically conductive. Choosing BN crucibles can bring you high quality sintering and long use life.

  • Ceramic Weld Pins

    Si3N4 Silicon Nitride Ceramic Welding Guide Pins

    Technial Ceramics are used to make the welding guide pins, which are used for projection welding and resistance welding in automotive industry. Ceramic pins are electrical insulated and high thermal shock resistant. Besides, they can be used up to 1,200 degree C. So they offer much longer service life and higher economic efficiency.
