Interpretation: The advantages and disadvantages of the use of ceramics in replacement joint bearing surfaces relative to metals have to be explained.
Biomedical material finds application in medical field. Artificial organs, dental implants and replacement of joints are done by biomedical material. Biomedical materials are made of composites, polymers and ceramics.
Ceramics are polymeric inorganic solid compounds consists of non-metal, metalloid or metal atoms held together by covalent and ionic bonds. When an inorganic substance is melted and solidified, it results in ceramics.
Ceramics are hard and have high melting points. They are heat insulators.
Ceramics have partly crystalline or crystalline or amorphous structure
