Bei technischen Bauteilen werden sehr unterschiedliche Eigenschaften gefordert. Um diesen Anforderungen gerecht zu werden, wurde eine breite Palette keramischer Werkstoffe mit sehr unterschiedlichen Eigenschaften entwickelt.

Detailliert sind hier die wichtigsten keramischen Werkstoffe aufgeführt. Natürlich sind auch Bauteile aus allen anderen Keramiken lieferbar.

Steatite exhibits at room temperature very good electrical resistivity and very small dielectric loss. Since many years it has been used for the production of insulators. Steatite parts are reasonably priced.

Alumina characterizes by excellent electrical isolation, thermal and chemical resistance and very high hardness. Due to these properties alumina parts find manifold application in electronics, electrical engineering, analytical instrumentation and in the chemical and textile industry. Alumina is the most common material used for structural ceramic parts.

Zirconia is applied as partially stabilized zirconia (PSZ) or tetragonal zirconia polycrystals (TZP). Both materials exhibit very good mechanical strength, fracture toughness and thermal shock resistance. The coefficient of thermal expansion of these materials is comparable with steel. Zirconia is often used in wear applications requiring improved fracture toughness and stiffness over alumina.

PSZ exhibits very high mechanical strength, fracture toughness and wear resistance. Due to these properties the parts made of PSZ zirconia are used in all technical sectors.

TZP zirconia shows the highest mechanical strength, fracture toughness and wear resistance. Parts made from this material satisfy the highest requirements concerning mechanical properties, surface roughness and edge stability. The specific properties of TZP materials enable the production of highest quality blades with superior quality.

Silicon Nitride exhibits excellent thermal shock resistance associated with very high mechanical strength and fracture toughness. Silicon nitride parts can be used in welding technique and metal industry. Due to very good tribological properties the ball bearings are made from this material.

Silicon Carbide characterizes the highest hardness, very good thermal shock resistance and very good chemical resistance. The thermal conductivity of silicon carbide is in the excess much higher than of many metals. Silicon carbide parts find application, where the highest wear and chemical resistance are required.
