摘　　要：介绍了α-TCP水化反应热力学基础及动力学模型,总结了原料粒度、水化温度、水化初始pH值等因素对α-TCP水化反应的影响;综述了α-TCP在制备骨水泥、羟基磷灰石晶须等方面的应用;提出了利用α-TCP水化反应,通过控制水化初始pH值等因素,制备羟基磷灰石晶须原位增强的磷酸钙基生物材料的设想。Mechanisms of the hydrolysis of α-TCP are reviewed, including thermodynamics and kinetic models. Effects of particle size, temperature, pH value, etc, on the hydrolysis of α-TCP are discussed. The applications of α-TCP, such as preparations of calcium phosphate cement, hydroxyapatite whisker, etc, are reviewed. Finally, the notion is put forward that the in-situ reinforced calcium phosphate-based biomaterials by HA whiskers can be prepared by hydrolysis of α-TCP via controlling the parameters of pH value, etc.
