摘要
以硅灰石矿物粉末为对象,用自动玛瑙乳钵进行干式微粉碎,研究了微粉碎过程中的机械力化学效应,考察分析了硅灰石在微粉碎过程中粉体粒度(激光衍射法)、比表面积(BET吸附法)、结晶构造畸变(有效德拜瓦洛参数-Bef)的变化特征,阐述了硅灰石从三斜晶系向单斜晶系的多型转变过程。
The Mechanochemical effect and change of crystal structure in the superfine grinding process of wollastonite are investigated in this paper.The characteristic of change about particle size(laser diffraction analyzer),specificsurface area (BET adsorotion metheod) strain of crystal structure (effective Debye walles parameter B eff ) for wollastonite in superfine grinding process is analyzed,and the polymorphic transition process from triclinic system into monoclinic system is explained.
