摘　　要：放电等离子烧结是一种快速烧结技术,具有热压等技术无法比拟的优点。将放电等离子烧结技术应用于羟基磷灰石类生物材料,不仅可在较低温度下实现快速致密化,防止羟基磷灰石在烧结过程中分解,使晶粒细化,还有助于提高材料的力学性能。将羟基磷灰石与其他材料复合并采用放电等离子烧结可赋予材料新的特性,弥补纯羟基磷灰石材料在力学性能方面的缺陷。今后对于该技术制备羟基磷灰石类生物材料的研究应当向多孔材料方向发展,并对材料进行多角度生物学评价。Spark plasma sintering is a kind of flash sintering technology,with advantages that cannot be matched by hot pressing.The application of spark plasma sintering technology in the preparation of hydroxyapatitebased biological materials can not only achieve rapid densification at a lower temperature and prevent hydroxyapatite from decomposing and grain refining,but also contribute to improving the mechanical properties of materials.With spark plasma sintering,the recombination of hydroxyapatite and other materials can provide materials with new features,and remedy the defect of pure hydroxyapatite materials in mechanical properties.The following researches on hydroxyapatite-based biological material preparation with this technology should focus more on porous materials and conduct multi-angle biological assessments for the materials.
