摘要
选用气流磨超音速气流作为机械力，对硅灰石、硬脂酸进行超细粉碎-表面改性。应用透射电子显微镜分析、观察硅灰石／硬脂酸复合粉体界面微观形貌及成分（Ca、Si、C）的变化规律。TEM能谱分析结果表明：从硅灰石到硬脂酸，Ca、Si含量逐渐降低，C含量则逐渐升高。
The interfacial behavior and variation rule of chemical comp osition (Ca, Si, C) at wollastonite/stearic acid interface pulverized-activat ed by supersonic airflow were investigated by transmission electron microscopy. The results show that the less the contents of Ca and Si and the higher the con tent of C at the wollastonite/stearic acid interface.
