【摘要】 研究了α -磷酸三钙 (α -TCP)骨水泥在生理盐水体外的溶解动力学。实验结果表明 ,α -TCP骨水泥静态溶解过程符合Avrami动力学模型方程式 :-ln(1-x) =kt1/2 ,并计算出溶解过程的表观活化能约为 9.87kJ/mol,此过程由沉积的羟基磷灰石 (HA)固膜扩散控制更多还原

【Abstract】 Dissolution kinetics of α-Tricalcium phosphate (α-TCP) bone cement in physiological saline dissolution is studied in the present paper. It shows that the dissolution process of α-TCP bone cement in static physiological saline accords with Avrami kinetic model equation: -ln(1-x)= kt 1/2,its activation energy is about 9.87kJ/mol.The process is controlled by diffusion of forming hydroxyapatite (HA) solid layer.更多还原
