2.Purpose:used in chemical industry
3.Best quality
Wear-resistance aluminium oxide ceramic ball
It has high strength and tenacity,good wear-resistance,high temperature and corrosion resistance,high rigidity,no-magnetism and electric insulation under normal temperature.When temperature at 600 C,the strength and hardness of zirconia ceramic ball is almost unchanged.Density:6.00g/cm3,the thermal expansion is close to metal’s.It can be used with metal together.Used for bearing,sealing parts ect.High purity zirconia beads is the most ideal grinding media at present.Widely applied in grinding and dispersing of material in non-metal mine,dope,printing pink,paint,dye, titanium pigment,pesticide,magnetic material ect industry.

Main property:
- High efficiency of grind: the proportion of zirconia ceramic bead is 1.6 times that of plain zirconia bead.Under the equal condition,it have higher grinding efficiency.
- Good fluidity:good roundness,fine surface,The abrasion to device is lower than other medias.
- Impulsion resistance and low abrasion:good tenacity for zirconia ceramic bead.No crazing or peel off.
