| Abstract Scope |
Hydroxyapatites, naturally occurring mineral calcium apatites with the formula Ca₅(PO₄)₆(OH)₂ have been investigated since past several decades for laser applications. It has been realized that major portion of the body bone is some form of hydroxyapatite which play very important roles in regeneration of cells in bones. With increasing osteoporosis in old generation due to calcium depletion, there is strong need to substitute elements such as gallium and titanium. The additives are very hard to dissolve and crystalline and glassy phases with precipitates are developed. We have synthesized using nanoparticles of parent components and have studied morphological transition of doped materials. We used some flux to enhance the transition of hexagonal morphology to glassy phase depending on the cooling conditions and compositions. We also evaluate effect of processing of these bioactive glassy materials in naphthalene-camphor eutectics which provides a pathway for low temperature processing. |
