Abstract

In this study, the influence of series of strontium substitutions on bioactive polymeric calcium phosphate cements has been evaluated in the present work. The cements were derived from a liquids that consisted of polcarboxylic acid (PCA), citric acid, potassium citrate and a calcium phosphate cement (CPC) powder that consisted of strontium-containing tricalcium phosphate (TCP ) and hydroxyapatite (HA) which is proved by the XRD and FTIR. A series of strontium-containing a-TCP/HA biphasic cement is prepared successfully. But the cement powder group of 20 atom % strontium amount was composition of b-TCP/HA biphase and did not set with the liquids.
