巴林石、寿山石透明度研究

Study on Transparency of Balin Stone and Shoushan Stone

通过分析巴林石、寿山石样品的FTIR与XRD光谱特征,指出有序度指数(OI)、结晶度指数(HI,DHI)及半高宽(FWHM(00l))在用于研究高岭石与地开石混合相样品的组分时具有局限性;计算了样品的有序度指数和结晶度指数并研究了各自与透明度之间的关系,结果证实,寿山石样品的透明度随其有序度与结晶度的增加而增大,但没有发现巴林石样品存在类似规律。

It is found that the order index（OI）,crystallinity indexes（HI and DHI） and the full width at half maximum（FWHM（001）） have the limitations when they are used to research the components of kaolinite-and-dickite-mixed phase samples by studying the FTIR and XRD spectrum characteristics of Balin stone and Shoushan stone samples.The order index and crystallinity indexes of the samples are calculated and the relationships between each and the transparency are studied.The results demonstrate that the transparency of Shoushan stone sample increases with the raise of the order index（calculated from FTIR data） and the crystallinity（calculated from XRD data）,but no similar regularity exists for the Balin stone samples.
