Surgical cermets are used regularly.
Ceramic biological uses.
In surface reactive ceramics such as hydroxyapatite and certain compositions of silicate glasses and glass ceramics are used the materials attach directly by chemical bonding with the bone bioactive fixation.
While we use conducting metals like copper to carry electricity from place to place we have to use ceramics to insulate high voltage electricity in places like power plant generators and transformers.
Ceramics are now commonly used in the medical fields as dental and bone implants.
Bioactive ceramics are also used as coatings on metallic implants.
The modern ceramic materials which are classified as advanced ceramics include silicon carbide and tungsten carbide.
Joint replacements are commonly coated with bioceramic materials to reduce wear and inflammatory response.
Traditional ceramic raw materials include clay minerals such as kaolinite whereas more recent materials include aluminium oxide more commonly known as alumina.
