The main components of zirconia beads are zirconia and yttrium oxide.

Zirconium dioxide, chemical formula is ZrO2, is the main oxide of zirconium, usually white, odorless and tasteless crystal, insoluble in water, hydrochloric acid and dilute

Sulfuric acid. Chemically inactive and has properties of high melting point, high resistivity, high refractive index and low coefficient of thermal expansion, making it an important

High temperature resistant materials, ceramic insulation materials and ceramic shading agent are also the main raw materials for artificial drilling.

Zirconia beads can be divided into 95 zirconia beads, 80 zirconia beads, 65 zirconia beads, zirconia-aluminum composite beads according to the zirconium content. Due to different compositions, the stage hardness and Vickers hardness are also different.

95 zirconia bead Vickers hardness 1250

80 zirconium Vickers hardness 1200

65 zirconium Vickers hardness 800

In addition to Vickers hardness, the choice of zircon beads also depends on whether the grinding equipment is suitable. The higher the hardness, the lower the wear and the more wear-resistant, but the stronger the impact force on the equipment, the faster the wear on the grinding cavity of the equipment. It is also necessary to consider the properties of the ground material, whether it is difficult to grind, and consider the comprehensive cost performance.

Selection method of zirconia beads

The larger the specific gravity of zirconia beads, the higher the grinding efficiency. High viscosity slurry should use beads with large specific gravity, such as grinding offset printing ink box inkjet ink, generally use Φ0.2-Φ0.8 zirconia beads.
