Ceramics

Definition

Ceramics are inorganic, non-metallic materials that are typically made from clay and other raw materials, and are hardened by heat. They exhibit a combination of desirable properties such as high strength, low density, chemical resistance, and thermal stability, making them suitable for a range of applications, including those in biomimetic materials where structures mimic natural systems.
