Advanced Ceramics

Alumina

Aluminum Oxide is the most widely used ceramic because it offers wear and corrosion resistance at a moderate price. Pressed and sintered to very high density, Aluminum Oxide grades provide high strength when considering their very high hardness.

Zirconia

Much tougher than Alumina, Zirconium Oxide is stabilized to provide exceptional strength combined with resistance to wear and corrosion in structural applications. This material is highly resistant to impact.

Silicon Nitride

Silicon Nitride is pressure-sintered to produce a high density ceramic with high fracture toughness, high temperature strength and exceptional resistance to thermal shock. It possesses high hardness and resistance to wear at elevated temperatures and resistance to corrosion.
