Zirconium Oxide (ZrO2)
The most common Ceramic balls available are Alumina Oxide (Al2O3), Silicon Nitride (Si3N4) and to a lesser extent Zirconium Oxide. These balls differ in properties and benefits.
Silicon Nitride offer very high resistance to wear and abrasion and weigh 60% less than steel. They are also resistant to corrosion and are anti magnetic. These balls are efficient at temperatures in excess of +1400°C and are designed for applications subject to great stress.
Alumina Oxide balls offer excellent resistance to abrasion, high temperatures and most corrosive agents. They are not recommended for processes in contact with hydrochloric and hydrofluoric acid.
Zirconium Oxide (ZrO2 –also known as zirconia) is a material with very high resistance to crack propagation. Zirconium oxide ceramics also have very high thermal expansion and are therefore often the material of choice for joining ceramic and steel. Another outstanding property combination is the very low thermal conductivity and high strength.
