Zirconia ceramic grinding ball beads are widely used as electronic Ceramics, nanomaterials, magnetic materials, silicon oxide, lithium powder, paint, titanium white, pharmaceutical foods, color paste, coatings, dyes, ink, pigments, papermaking, cosmetics, resins, adhesives, emulsions, medicines, petroleum, ultrafine grinding and dispersion of pesticide, daily chemical and other special chemical industry
It is widely used for grinding, dispersing and polishing as following: inkjets inks, electronic slurries, raw material of battery, screen printing inks, coating, painting, pigment, ceramic and cosmetic, jewelry and other nanoparticles products.






A. Zirconium oxide ceramic beads ong lifespan: 30 times longer life than glass beads, 6 times than zirconium silicate beads.
B.High efficiency: around 6 times higher than glass beads; 2 times than zirconium silicate beads.
C. Excellent wear resistance and fracture toughness is especially suited for high-solid-phase high viscosity, high hardness of thepaste for grinding and dispersing of pure; good match at the same time high input energy and the high shear machine sanding.
