Strontium doped hydroxyapatite (Sr-doped HA) nanopowder has been synthesized using a sol-gel method. The concentration of strontium was varied at 2, 5, 10 and 15 mol%. The as synthesized powders were calcined at temperatures of 500-900�C. The calcined white Sr-doped HA powders were characterized usi...
