What Does Ceramic Mean?

Ceramics are inorganic, non-metallic substances generated by heating clay to a very high temperature so that it hardens. Ceramics are more resistant to corrosion than metals or alloys.

Corrosionpedia Explains Ceramic

Ceramics are sometimes adhered to metallic surfaces to prevent corrosion and material degradation. They are used in a variety of products from wristwatches to cars and spacecraft for this purpose. The incorporation of ceramics (known as a cermet) can modify a material's properties such as density, conductivity, brittleness, insulation and magnetism.

Advanced ceramics have become more common as their development has progressed. Such ceramics are not purely clay but are generated using oxides or non-oxides. The oxides used include alumina and zirconia, while non-oxides include silicon carbide (SiC) and molybdenum disilicide.
