Ceramics

Mechanical properties : which reflect the behavior of materials ,deformed by a set of forces

Physical properties : which describe the behavior of materials subjected to the action of temperature ,electric or magnetic fields ,or light .

Chemical properties : which characterize the behavior of material in a reactive environment .
