Ceramic components are used in places where the specific properties of ceramics - such as hardness, strength and wear-resistance - have an added value.
Ceramics are very hard, lightweight, have a high mechanical strength, an excellent wear-resistance and low friction - all necessary for positioning.
Ceramic parts are very well suitable for use within bearings, to carry loads at combined rotational and linear movements under extreme conditions.
In order to position accurately in vacuum - as in applications with extreme ultraviolet light (EUV) - high stiffness, low expansion chemically resistant ceramic materials are necessary, with high purity that do not degas.
In most mixing processes, there is a close contact between the mixed substances and the mixing equipment. Wear-resistant and chemically inert ceramics can offer many advantages here.
Ceramic materials offer good wear-resistance and chemical resistance as well as near perfect limited lubrication properties in sealing solutions.
Depending on the composition, ceramic materials can have a very high heat conductivity or a rather high electrical conductivity, and hence can be good heat or electrical conductors.
Transporting a liquid, with close contact between the pump material and the liquid, can result in wear, thermal and chemical degradation. Ceramic bearings that are lubricated by the pumped liquid offer a solution here.
Drives under specific, extreme conditions require materials with exceptional properties. Hard, strong and wear-resistant ceramics may play a role here.
In precision measuring equipment, ceramic parts are indispensable. Stiffness, low weight, wear-resistance and a smooth surface structure are essential here.
