Zirconia Ceramic Rods, Pins,Plungers, Shafts

Yttria Stabilized Zirconia Ceramics

Zirconia is stabilized in the cubic crystal structure to avoid cracking and mechanical weakening during heating and cooling. In addition to their refractoriness, they offer low thermal conductivity and are electrical conductors above 800 ℃. They also possess the unique ability to allow oxygen ions to move freely through the crystal structure above 600 ℃.

Added yttria gives zirconia more strength and lowers the chances of cracking from impact compared to standard zirconia, alumina, and silicon nitride ceramics. If cracks do occur, they will not spread, extending the life and reliability of this material.

Zirconia ceramic rods, bars, and plungers are made of zirconium oxide (ZrO2), these rods and bars, made of zirconia ceramics, are used in the shaft, plunger, sealing structure, automobile industry, oil drilling, insulation parts and other applications.

Zirconia ceramic rods have the advantages of super hardness, high wear-resisting, good corrosion resistance, high-temperature tolerance, high mechanical strength, good chemical stability, high density, high smoothness and so on.

Zirconia ceramic rods are used in the shaft, plunger, sealing structure,oil drilling equipment, Insulation parts in electrical equipment,pump and valve, high temperature furnaces, electrical insulators, optical instrument, medical and dental implants, automotive parts,aerospace components, electronics, thermal barrier coatings, semiconductor processing, biomedical instruments, chemical processing, wear-resistant components, laboratory equipment, advanced fuel cells and energy storage devices.

Zirconia ceramic rods are often used as sleeve bearings and shafts instead of metal.

Zirconia ceramic rods we are supplying are available in a variety of shapes, dimensions and tolerances depending on customers’ requirements.
