摘　　要：采用纳米球磨-超声搅拌工艺制备了β-磷酸三钙粉体,并与传统固相合成工艺进行了对比研究。采用差示扫描量热(DSC)、X射线衍射(XRD)、红外(FTIR)、纳米粒度测试、扫描电镜(SEM)、透射电镜(TEM)及X射线荧光光谱(XRF)等手段对两种工艺所制备粉体进行了纯度和粒度表征。结果表明:相比传统工艺,经过纳米球磨-超声搅拌工艺制备出的β-TCP粉体纯度可达97%以上,平均粒径为666 nm。粉体的纯度高、粒径分布更均匀。同时,纳米球磨加工后的原料平均粒度更小,分散性更好。该工艺有望用于粉体材料的固相合成。β-Tricalcium phosphate powders were prepared by nano ball milling and ultrasonic stirring process and compared with conventional process in this research. The purity and particle size of β-TCP powders were investigated by differential scanning calorimetry（DSC）, X-ray diffraction（XRD）, Fourier transform infrared spectroscope（FTIR）, nanoparticle test, scanning electronic microscopy（SEM）, transmission electron microscope（TEM） and X-ray fluorescence spectrum（XRF）. The results reveal that the purity of β-TCP powders prepared by the nano ball milling and ultrasonic stirring process can reach over 97%, and the powders average particle size is 666 nm, with high purity and uniform particle size. Moreover, the raw materials with small particle size and good dispersion can be processed through nano ball milling. This process has great potential in the synthesis of inorganic powders by solid-state synthesis.
