1. Used as Ceramic Materials

Spherical micro-powders possess excellent compression molding and sintering properties, which are extremely favorable for manufacturing high-quality ceramic products.

Zirconia beads and zirconia grinding balls both refer to spherical grinding media made from zirconia as the raw material. They are specialized grinding media primarily used for the ultra-fine grinding and dispersion of high-viscosity and high-hardness materials, and are widely applied in the milling of materials across industries including electronic ceramics, magnetic materials, lithium battery materials, food, pigments, dyes, coatings, inks and special chemical engineering. Terms such as zirconia beads, zirconia grinding beads, zirconia balls, yttrium-stabilized zirconia beads, 95 zirconia beads, pure zirconia beads, cerium-stabilized zirconia beads, 80 zirconia beads, zirconium silicate beads, 65 zirconia beads—these are all designations used in the grinding industry for zirconia grinding media balls with different material compositions and zirconia content ratios.

The planetary high-energy ball mill is used for preparing ultra-fine powders. Its working principle is that during operation, the grinding jars rely on the combined force generated by the revolution and rotation of grinding balls to impact and pulverize the materials. Factors affecting the grinding effect include grinding time, grinding speed, and solid content of the grinding materials. 

Both zirconia ceramic balls and silicon nitride ceramic balls fall into the category of ceramic balls. They can be used as grinding media, and those with high precision can also serve as valve balls and bearing balls, sharing overlapping applications. However, significant differences exist between them in terms of composition and properties.

As a grinding material, zirconia balls are distinguished by their high density, high hardness, and excellent toughness. Although their price is higher than that of other abrasives, they offer excellent overall cost-effectiveness because they can save significant costs in long-term use.

Zirconia beads are mostly composed of tetragonal zirconia, hence also known as "TZP" zirconia beads. Made from micron and sub-nanometer grade zirconia and yttria as raw materials, they are a type of grinding media specifically designed for the ultra-fine grinding and dispersion of materials requiring zero contamination, as well as high-viscosity and high-hardness substances.
