Optimization of process parameters using taguchi method for preparation of macroporous hydroxyapatite by foaming and gelcasting

Abstract

Implant used for repair and replacement of bone should have a newlinecomposition that matches bone and a morphology that can support bone newlineingrowth into the implant helping better regeneration and bone bonding In newlinethis view hydroxyapatite prepared with macroporous morphology pore size newline 100 and#956;m was identified to be suitable for implant application and was newlineprepared in the present work newlineHydroxyapatite powder preparation in the present work was carried newlineout by solgel method to ensure proper purity of the obtained powder for newlineimplant application Calcium nitrate and triethyl phosphate were used to newlineprepare the sol Calcination was carried out at 600oC following gelation The newlinepowder obtained after calcination was characterized by XRD and SEM newline newline
