Fabrication and characterization of strontium-doped hydroxypatite bioceramics scaffolds for bone implant application: a preliminary study

In this study, strontium doped hydroxyapatite (SrHA) nanopowder was synthesized through a sol-gel method. Strontium concentration was varied from 0 to 15 mol%. The obtained gel was then dried and subsequently subjected to 900 ºC calcination. SrHA porous bodies were fabricated by using polymeric spon...
