In this research, effect of soaking time of a new synthesized hydroxyapatite-based bone cement in simulated body fluid (SBF) on the final phase and strength has been studied. The powder section of the cement has been synthesized by using tricalcium phosphate, calcium carbonate and anhydrous dicalcium phosphate. The liquid phase of the cement consists of different concentrations of NaH2PO4.2H2O....
