Ⅰ.Zirconia Ceramic Ball Product Introduction:
Zirconia ceramic balls are industrial grinding media made from zirconia (ZrO₂) as the base material. They possess high density, high hardness, and excellent wear resistance. Their main component is yttria-stabilized zirconia (Y-TZP), and through yttria stabilization treatment, the critical stress value for crystal phase transformation can be increased to over 900 MPa.
Ⅱ.Main Uses and Application Fields
Grinding and Polishing: Used for polishing and deburring the surface of metal workpieces such as stainless steel, and for ultra-fine grinding of materials such as inks and coatings.
Industrial Processing: Sandblasting for rust removal, high-precision bearing balls, valve balls, and other precision components.
Coatings and Pigments Industry: Ensures uniform dispersion and high gloss of pigments.
Ceramics and Electronic Materials: Grinding of high-hardness ceramic powders and electronic materials.
Pharmaceutical Industry: Grinding of drug particles to ensure uniform dispersion and high purity of pharmaceuticals.
Biomedical Applications: Used in medical devices such as artificial joints.
