Ceramic

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.
