The usages of zirconia ceramic sand:
Zirconia ceramic sand are high-performance spherical abrasives widely used across multiple industries.
In electronic manufacturing, they remove burrs, oxide films and dirt from circuit parts, connectors and component shells without scratching delicate surfaces.
For metal processing, they perform shot peening to strengthen metal workpieces, eliminate stress and improve fatigue resistance. They also achieve uniform matte finishes on hardware, auto parts and mold surfaces.
They serve well in surface cleaning & polishing for jewelry, glass and precision instruments. Additionally, ceramic beads act as grinding media for wet/dry grinding, dispersion and mixing of pigments, coatings and chemical powders.
With high hardness, chemical stability and reusability, they replace glass beads and traditional abrasives for fine blasting and finishing work.
