Characteristics Of Zirconia Ceramic Balls

Characteristics Of Zirconia Ceramic Balls

Zirconia balls belong to functional ceramics and have been widely used in many fields.

1. Physical properties

Zirconia balls are resistant to impact and have low wear. Due to the high content of ZrO2 in zirconia ball milling beads, they have physical advantages such as high density, high toughness, low wear, no broken balls, and peeling, which reduces the dispersion and pollution of abrasives. The wear of zirconia balls can be many times lower than that of ordinary ceramic microspheres. Meanwhile, the more complex the structure of zirconia balls, the lower their thermal conductivity, and the better their insulation performance.

2. Mechanical properties

The elastic modulus of zirconia balls is generally high and less prone to deformation. Even at high temperatures, the deformation is very small. At the same time, zirconia balls have high strength, hardness, and wear resistance, and their high strength can be maintained above 100%. Most metals will soften or even melt at this temperature. Compared with grinding balls made of other materials, grinding balls made of zirconia balls can increase grinding load, speed up, and extend their lifespan several times.

3. Chemical properties

The microstructure of zirconia balls is very stable, and it is usually impossible to interact with oxidation in the medium. Not only does it not oxidize at room temperature, but it also does not oxidize even under high temperature conditions. Zirconia balls have strong resistance to corrosion by acids, bases, salts, and molten non-ferrous metals. Zirconia balls can resist corrosion from almost all inorganic acids and most alkaline solutions, except for hydrofluoric acid and molten sodium hydroxide. In short, the chemical stability of zirconia balls is very good.
