Zirconia balls are made of micrometer and subnanometer zirconia and yttrium oxide as raw materials, and are used for ultra-fine grinding and dispersion of materials requiring "zero pollution" and high viscosity and high hardness. Mainly used in electronic ceramics, magnetic materials, zirconia, silicon oxide, zirconium silicate, titanium dioxide, medicine and food, pigments, dyes, inks, special chemical industry.

Development process
The substance zirconia first appeared, was extracted from gemstones by a foreigner, and was then applied to gas lampshades. Later, this material has been applied to refractory materials, coloring and abrasives.
In 1875, an Australian scholar proposed that grinding balls could increase the toughness of products by adding zirconium. This idea was very avant-garde at the time, and quite a number of experts and scholars began to explore this field.
In the early 1920s, zirconia was used in the field of refractory materials, until the mid-1970s, the international advanced countries in Europe, the United States and Japan competed to invest in research and development of zirconia production technology and zirconia series product production, the application of zirconia extended to structural materials and functional materials. At the same time, zirconia is also one of the high-performance new materials encouraged by the national industrial policy. In recent decades, people have developed many new products with excellent performance, so its application field is also expanding.

Classification of zirconia balls
There are many classifications of zirconia balls, but only the following are really suitable for grinding machines: yttrium stabilized zirconia balls, cerium stabilized zirconia balls, 80 zirconia balls and zirconia silicate balls.
(1) yttrium stabilized zirconia balls Because the zirconia content of such zirconia balls is approximately 95%, it is also commonly called "95 zirconia" or "pure zirconia balls". The use of rare earth yttrium oxide as a stabilizer, the use of high whiteness, high fineness of raw materials to ensure that the material does not pollute. These zirconium balls are suitable for use in sanding machines.
(2) Cerium stabilized zirconia balls Because the zirconia content of such zirconia balls is approximately 80%, cerium stabilized zirconia balls are one of the higher density of all zirconia series zirconia balls, coupled with the characteristics of such zirconia balls, especially suitable for grinding and polishing.
(3), 80 zirconium balls 80 zirconium balls zirconia content of approximately 80%, so it is often called "80 zirconium". It has better grinding characteristics, so that it has a high cost performance. It has been widely used in all walks of life.
(4), zirconium silicate balls Zirconia content of zirconium silicate balls is approximately 65%, so it is often called "65 zirconium". Zirconium silicate balls are made by the advanced process of titrating in the electrolyte and sintering at high temperature. There are no pores and cavities in the balls. Medium density and hardness suitable for medium and low viscosity slurry grinding.
