摘要
本文借助偏光显微镜、化学分析、X 射线衍射分析等方法,对滑石粘土的外貌、矿物成分、化学成分、在焙烧过程中的相变化进行了研究,还介绍了它在陶瓷工业中的应用.滑石粘土广布于我国江西的宜春、萍乡、乐平,湖南的醴陵、浏阳一带,其化学成分特征是MgO 含量高,Al_2O_3、Fe_2O_3含量低,主要矿物成分为滑石,伴生矿物有方解石、石英、海泡石、蒙脱石等.它具有塑性粘土的工艺物理性能,所以是陶瓷工业的重要原料.
The morphology,mineralogical and chemical compositions,phase variation in the process of burning of tale clay is also touched have been studied by the polarizing microscopy,chemical analysis,X-ray diffraction etc… Talc clay is widely distributed in China.It occurs in Pingxian,Yichun,Leping of Jiangxi Prov- ince and Liling,Liuyang of Hunan Province.The chemical composition of talc clay is characterized by high MgO,low Al_2O_3and Fe_2O_3.Mineralogically it consists of talc accompanied with calcite, quartz,sepiolite,montmorillonite etc.It posseses the technological and physical properties of plastic clay,so it is an important raw material of the ceramic indutry.
