Solid substances divided into very small particles, primarily pulverized, non organic and non metallid, obtained by union or combination of metallic cations with one or more metalloid anions following different processes.

Ceramics have after powder sintering a crystalline structure with possibility of presence of vitreous phases.

The existing ceramics are:
• traditional ceramics (glasses, hydrolic blinders…)
• ceramics for biomedical applications
• technical ceramics (oxides, carbides, nitrides, borides, silicides…)
