Zirconia beads are made from micrometer and sub nanometer sized zirconia and yttrium oxide as raw materials, used for ultrafine grinding and dispersion of materials that require "zero pollution" and high viscosity and hardness.
Zirconia beads (referred to as "TZP" zirconia beads) are first made from micrometer and sub nanometer level raw materials using good processes. Mainly used for ultrafine grinding and dispersion of materials that require "zero pollution" and high viscosity and hardness, such as electronic ceramics, magnetic materials, zirconia, silica, zirconium silicate, titanium dioxide, pharmaceutical and food, pigments, dyes, inks, and specialty chemical industries.

● The overall roundness of the sphere is good, with a smooth surface and a pearl like luster;
● Has good toughness, impact resistance, and does not break during high-speed operation;
● The wear resistance of TZP zirconium beads is 30-50 times that of glass beads;
● TZP zirconium beads have a higher density than other grinding beads, with high grinding efficiency, which can increase the solid content of the material or increase the material flow rate.
True specific gravity: 6.02g/cm3 Zirconia 94.8%
Bulk density 3.5-3.7g/cm3 Yttrium oxide 5%
Mohs hardness 9.0, other 0.2%
Characteristic:
1. Low (ppm level) wear.
2. A high hardness that is not easily broken is beneficial for the grinding of high hardness materials.
3. High density can effectively improve grinding efficiency.
Scope of application: Coatings, inks, non-metallic minerals, electronic glazes, papermaking
With the high demand for product quality, having suitable grinding equipment, if matched with appropriate grinding media, can help improve the production efficiency of the grinding machine and the service life of the equipment. Years of experience have taught us that in the process of selecting grinding media, in addition to considering the density and size of the grinding beads, the sphericity and wear of the grinding beads are also important, as they determine the quality and efficiency of the product. The size selection of the medium depends on the original particle size of the material and the fineness of the product.

L95 Yttrium stabilized zirconia beads

Using yttrium oxide as a stabilizer, it is a high-purity, high-strength, high-density, strong acid and alkali resistant spherical particle with low wear and minimal wear on equipment, suitable for high value-added product fields.
L65 zirconium silicate beads
Made by titration molding in electrolyte and high-temperature sintering phase determination process. The beads are composed of dense zirconium silicate particles with low wear rate. Suitable for grinding medium and low viscosity slurries, it is a practical and economical grinding medium.
L80 cerium stabilized zirconia beads
Made by using cerium oxide as a stabilizing agent, titration molding, and calcination phase fixation process. The microstructure of beads is delicate and has a high density, making them suitable for dispersing and grinding high solid and difficult to disperse materials.
