The extraordinary characteristics possessed by zirconia balls

The appearance of zirconia ball was extracted from gem by a foreigner, and then it was used on gas lamp shade. Later, zirconia balls were used in refractory materials, coloring, and abrasives. In the past decade, many new products with excellent performance have been developed, so the application field of zirconia balls is constantly expanding.

Zirconia balls are inorganic non-metallic materials with high temperature resistance, corrosion resistance, wear resistance, and high conductivity. They were applied in the field of refractory materials in the early 1920s, and since the mid-1970s, advanced countries have invested in research and development of zirconia ball production technology and zirconia ball series products, further expanding the application of zirconia balls to structural and functional materials. At the same time, zirconia balls are also one of the high-performance new materials encouraged by national industrial policies. Currently, zirconia balls are widely used in various industries.

As a medium ball for dispersing and grinding materials, zirconia balls (or zirconia microspheres) need to solve the problem of transforming from monoclinic to tetragonal crystal system within the usual temperature range (0-80 ℃). Doping alkaline earth and rare earth oxides is an effective method, which has led to the emergence of different stabilizers such as yttrium oxide, cerium oxide, magnesium oxide, and calcium oxide. Practice has proven that zirconia beads stabilized with yttrium oxide and cerium oxide are ideal grinding media with high fracture strength and wear resistance.

We look at the surface of zirconia balls, and if we had told you the name beforehand, you might have mistaken it for a pearl. Zirconia balls, when viewed from the surface, have a smooth surface and a pearl like luster, making them an excellent grinding medium. At present, zirconia balls are widely used in various industries such as non-metallic minerals, coatings, inks, etc. You can see them performing grinding work.

Zirconia balls, as an excellent grinding medium, have high strength, toughness, wear resistance, corrosion resistance, good insulation, and other characteristics at room temperature. In terms of thermal expansion coefficient, they are similar to steel. We placed this medium at a high temperature of 600 ℃, and you can observe that the hardness and strength of the zirconia balls have hardly changed. Zirconia balls are made using yttrium oxide as a stabilizer and a special manufacturing process of high-temperature roasting and phase fixation. So, what are the extraordinary characteristics of zirconia balls?

1、 High grinding performance. Zirconia balls stabilized with yttria have better grinding performance compared to ordinary materials.

2、 Good liquidity. From the surface observation of this medium, you will see that zirconia balls have a smooth surface and good roundness, and their wear degree is lower than other media when used in equipment.

3、 Resistant to impact and wear. Zirconia balls have good toughness at high temperatures and will not crack or break even when used in high-intensity equipment.

4、 The price of the material is moderate. By using zirconia balls as a material and analyzing various aspects comprehensively, it can save a lot of costs both in equipment and labor, and the quality of the product will also be improved
