Ceramic is a material that is neither a metal nor a polymer.
Examples of ceramics include earthenware, stoneware and porcelain, but also could include glass, diamonds, superconductors and implants.
Ceramics is formed by heating (in, for example, an oven), sometimes in combination with pressure, wherein at least two elements are present.
One of these elements is non-metallic and the other may be both the metallic and non-metallic.
Ceramics is applied to the flanks of some wheels in order to improve the braking performance and as a mixing material in metal matrix composites.
It is also used in the form of minuscule ‘beads’ and also in (chain) lubricants used.
