β-磷酸三钙粉末的机械化学合成

MECHANOCHEMICAL PREPARATION OF β- TRICALCIUM PHOSPHATE POWDER.

利用搅拌磨的机械化学效应合成了超细β－Ｃａ３（ＰＯ４）２）（β－ＴＣＰ）粉末，研究了磨矿时间、热处理温度和时间对β－ＴＣＰ粉末性能的影响。结果表明，用搅拌磨机械化学法合成β－ＴＣＰ，工艺简单、周期短、粉末平均粒径小于０．５μｍ。同时探讨了机械化学法合成β－ＴＣＰ的机理。

Ultra - fine β- TCP powder is prepared by mechanochemical method with stirred mill. The effect. of grinding time , thermal treating temperature and time on properties of β- TCP powder are discussed. The results of test show that the above - mentioned method has simple process and short duration of preparation , the average parti- cle size ofβ- TCP powder obtained can be less than 0. 5 μm The mechanism of mechano - chemical preparation of β- TCP powder is also discussed.
