Contents: Thermokinetics method was used to study the self-setting kinetics of a new kind of calcium phosphate cement (CPC) in the present study. A calcium-deficient hydroxyapatite CPC was developed by using α-TCP and other calcium phosphate bioceramics. The mixing liquids used were deionized water and 0.25 M NaH2PO4/Na2HPO4, respectively. The calorimetric curves, heat evolution curves and total heat evolution in the setting and hardening process of CPC were determined. It has been found that mixing liquids, reaction temperature had influences on the calorimetric curves and heat evolution, and mixing liquids exhibited the greatest influence on the kinetics of CPC during the self-setting and hardening process. Based on the calorimetric curves obtained, the kinetic model equation was simulated, and the reaction control step was determined.
