چکیده مقاله:
Calcium phosphate cements (CPCs), using B-tricalcium phosphate (ß-TCP, Ca۳ (P۰۴)۲), dicalcium phosphate (DCP, CaHP۰۴), calcium carbonate (Ca CO۳), and hydroxylapatite (HAp, Ca۱۰(P۰۴)۶(OH)۲) as powder cement and disodium hydrogen phosphate (Na۲HP۰۴) solution as liquid component were prepared. After mixing the powder and liquid constituents, injectable and self-setting calcium phosphate cements (CPCs) were prepared with different liquid to powder ratios (UP) that formed hydroxylapatite and ß-tricalcium phosphate as the only end products, which were characterized by FTIR, XRD and SEM techniques. The results showed that, at certain concentration of Na۲HP۰۴ (۶ wt%), the initial and final setting times decreased by decreasing the UP ratio.
