Deutsch: Keramik / Español: Cerámica / Português: Cerâmica / Français: Cêramique / Italiano: Ceramica
A ceramic is an inorganic, nonmetallic solid prepared by the action of heat and subsequent cooling. Ceramic materials may have a crystalline or partly crystalline structure, or may be amorphous (e.g., a glass). Because most common ceramics are crystalline, the definition of ceramic is often restricted to inorganic crystalline materials, as opposed to the noncrystalline glasses, a distinction followed here.
In an industrial or industry context, "ceramic" refers to a type of material that is made from clay or other non-metallic minerals that are fired at high temperatures to produce a hard and brittle material. Ceramics are known for their high temperature resistance, wear resistance, and electrical insulation properties.
Examples of ceramics in an industrial context include:
- Refractory ceramics used in high temperature furnace linings, kilns, and heat exchangers
- Structural ceramics used in the aerospace, automotive, and electronics industries
- Technical ceramics used in cutting tools, wear parts, and electrical components
- Bioceramics used in medical implants and dental restorations
- Advanced ceramics used in sensors, fuel cells, and catalysts
- Decorative ceramics used in tile and other architectural finishes.
