Industrial Advanced Al2O3 Alumina Ceramic Wear Resistance Rings

Alumina (aluminum oxide) is the most important, widely used and cost effective oxide ceramic material. The technical alumina ceramics contain at least 80% of aluminum oxide (AL2O3). Small amounts of silica (SiO2), magnesia (MgO) and zirconia (ZrO2) may be added to alumina ceramics. Addition of zirconia to alumina ceramic results in considerable increase of the material fracture toughness. 

Typical Alumina characteristics include:

*High mechanical strength (flexural strength) and hardness;

*High wear resistance;

*High resistance to chemical attacks of strong acids and alkali even at high temperatures;

*High stiffness;

*Excellent insulating properties;

*Low coefficient of thermal expansion;

*Good fracture toughness;

*Good thermal conductivity;

*Good biocompatibility.
