What is Ceramics

A kind of material that is "bone like" based on the specific ratios of calcium and phosphorous in particular crystalline structures. Ceramics are inorganic, nonmetallic, nonpolymeric materials manufactured by compacting and sintering at elevated temperatures. They are divided into metallic oxides or other compounds. Oxide ceramics are introduced for surgical implant devices as it offers high strength, inertness to biodegradation, low thermal and electrical conductivity and an elastic modulus similar to bone but tend to be more brittle.

Whilst their tissue compatibility is considered good, some ceramics released soluble silicates which caused adverse tissue reactions. Unfortunately ceramic materials have low tensile and transverse strengths, low impact resistance and are not easy to mould
