Description

Zirconia Ball With characters of large density, high mechanical strength, high chemical stability, low thermal expansion factor and high abrasion resistance, Zirconia ball is mainly applied as grinding media for various grinding machines. It can provide high grinding efficiency, low noise, pollution free to materials, and long useful life. Zirconia ceramic is also applied widely as bearing material in traditional bearings of precision machine tool, high-speed electrical machine, automobile, and air conditioner. So, it&#**9;s applied in industries of petrochemical, chemical, aviation, and navigation. In accordance with customer specific needs, zirconia ceramic can be contract manufactured in the form of valve mandrill, valve body, tube, sheet, or bearing. 　 　 Technical Specification Item Index ZrO2+Y2O3 , % *9.8 Density, g/cm3 6.0±0.1 Compressive strength, MPa **0 Loss on grinding , % 0.***0.*3 　 　 Product Size Item Diameter, mm Ball ceramic φ**3 φ***0 φ*5 φ*0 φ*5 Column ceramic φ*0x*0 φ*5x*5 φ*0x*0
