- Product Description
-
Zirconia balls are special ceramic balls made from high-purity zirconia (ZrO₂) and stabilizers (such as yttrium oxide Y₂O₃, magnesium oxide MgO, etc.) through advanced manufacturing processes and high-temperature sintering. They are representative of high-performance grinding media and advanced ceramic components, renowned for their extremely high wear resistance and excellent comprehensive performance.
Core performance advantage：
- Outstanding corrosion resistance: Capable of withstanding the erosion of various acids, alkalis and organic solvents. It is an ideal alternative to metal materials for corrosive medium transportation systems.
- Excellent mechanical properties: Possessing high hardness, high wear resistance and high compressive strength. Its unique phase transformation toughening mechanism enables it to have good toughness, effectively preventing impact fragmentation.
- Insulation and magnetic isolation properties: Non-conductive and non-magnetic, suitable for interference prevention scenarios in precision instruments, electronics, and medical equipment;
- High-temperature resistance and self-lubrication: Performs stably in high-temperature environments, featuring low friction coefficient and self-lubrication properties, meeting the requirements of oil-free lubrication conditions.
Application fields:
- As valve balls: They have been successfully applied in high-pressure homogenizers, diaphragm pumps, metering pumps, oilfield pumping units, high-pressure spray guns and other equipment, effectively enhancing the service life and sealing reliability of the valves under corrosive and wear conditions.
- As bearing balls: They are used in all-ceramic bearings, meeting the demanding requirements of high speed, insulation, corrosion resistance, and high temperature resistance.
- As functional balls: They are widely used in force-measuring sensors, track balls, and fine grinding media, which are in situations with strict requirements for precision, hardness, and chemical stability.
