primary mineral of vermiculite

The paper detailedly account and discussed the geologic feature of vermiculite ore deposits inChina, and then discussed their mineralizing rules and the geologic process of phlogopite (biotite) changinginto vermiculite.

本文对我国主要蛭石矿床的地质特征进行了论述,并在此基础上探讨了其成矿规律及金(黑)云母蚀变成蛭石的地质作用,并以此为根据提出了蛭石矿床的较为合理的成因分类。

The vermiculite concentrate is organic modified with hexadecyl trimethyl ammonium bromide(HDTMAB) and vermiculite and organo-vermiculite are characterized by X-ray diffraction spectrometry(XRD),infrared spectrometry(IR),differential scanning calorimetry(DSC) and gravitational thermal analysis(TG).

采用十六烷基三甲基溴化铵(HDTMAB)对蛭石精矿进行了有机改性,利用X射线衍射法(XRD)、红外光谱(IR)、差示扫描量热法(DSC)和热失重分析(TG)对蛭石精矿和有机改性蛭石进行了表征。
