Application of apatite based materials for circumstances and microstructural evaluation

Abstract

Although hydroxyapatite is a major inorganic constituents of bones and teeth, it is known that the hydroxyapatite can exchange various ions with the ions of the hydroxyapatite lattice. Apatite based materials are expected to apply for absorbents of harmful metal ions. Various types of hydroxyapatites were prepared by sintering technique. The ability of Cd ion and Cr ion into hydroxyapatite structure and surface was investigated.
