摘　　要：采用固相烧结法制备了无定形和β晶型的聚磷酸钙(CPP)粉体,以β-CPP为基础粉料掺入氟化铵,并以聚氨酯泡沫为模板,采用有机泡沫浸渍法制备了掺氟多孔β-CPP生物陶瓷。本研究以氟化铵为导入剂引进氟离子,通过调节不同的掺杂量,研究了氟离子对多孔体物理性能的影响,如抗折强度、气孔率、微观形貌等。研究表明,氟化铵的引入可以显著地改变β-CPP浆料粘度和流变性,并促进多孔体的烧结,降低气孔率,使其更加致密化,提高多孔体强度。The amorphous and beta crystalline form of calcium polyphosphate （CPP） powder were fabricated by solid-state reaction method, porous calcium polyphosphate bioceramics prepared by impregnation with organic foam polyurethane foam as a template.In this study, using ammonium fluoride as introducing agent to introduce fluorine ion, by adjusting the amount of different doping, investigating the influence of fluoride ion on the physical properties of the porous body, such as flexural strength, porosity, morphology,etc.The study shows that the introduction of ammonium fluoride can be significantly changing the β-CPP slurry＇ s viscosity and theology, and to promote the sintering of the porous body to reduce porosity, and to make it more compact, and to improve the strength of the porous body.
