Abstract:
Hydroxyapatite Ca1o(P04)6(0H)2 is an important biomaterial and is the principal
inorganic constituent of bones and teeth. It is also used as the replacement of heart
valves, hip joints and other implants in the human body. A novel procedure to produce
porous hydroxyapatite from the waste seahells is reported.. The seahells were
them1ally treated and hydroxyapatite was produced from the calcined seahells through
chemical route. The morphology of hydroxyapatite produced from seashell is
analyzed by using Scanning Electron Microscope and the element composition of
different phase is identified by using Energy Dispersive X-Ray. The powder was
characterized by X-Ray Diffraction and Fourier Transform Infrared Spectroscopy
(FTIR). Hydroxyapatite that produced with a smaller particle size and higher
temperature is 53µm with the temperature of 550
°
C.
