INSULATION

There are ceramic materials with a very low heat or electrical conductivity, that consequently insulate thermally or electrically.

 

SEPARATION

The good wear-resistance and high mechanical strength make ceramics very suitable as a material for mechanical separation processes. Especially when abrasive particles have to be separated from gases or liquids.

LUBRICATION

High temperature lubrication is possible by using hexagonal boron nitride.

Just like carbon exists in the form of hard diamond and soft graphite, boron nitride can exist in the hard cubic structure and the soft, 'lubricating' hexagonal crystal structure.

APPLICATIONS

POSITIONING

Ceramics are very hard, have a high mechanical strength, an excellent wear-resistance and low friction. All this is useful for repeated, accurate positioning (e.g. zero point tooling systems).
