X射线荧光光谱法测定叶蜡石、高岭土的化学成分

叶蜡石、高岭土是玻璃纤维行业生产最主要原料。随着玻璃纤维行业的发展，其用量每年大幅度上升，因此对于叶蜡石质量要求越来越高。传统的湿化学方法已经很难满足要求。本文阐述了采用熔融制样x射线荧光光谱法测定叶蜡石、高岭土的SiO2、Al2O3、Fe2O3、TiO2、K2O、Na2O、CaO、MgO、S这9种成分的含量，所得结果与化学分析结果相符，同时采用荧光光谱法更为迅速快捷，是实际生产中的化学成分分析的一种有效方法。

Determination of Chemical Compositions of Pyrophyllite and Kaolin by X-ray Fluorescence Spectrometry

Pyrophyllite and kaolin are major raw materials for producing glass fibers.With the growth of glass fiber industry,their usage increases significantly year by year,and the quality requirements for them become increasingly higher.As the traditional chemical analysis is no longer satisfactory,X-ray fluorescence spectrometry has been used to test samples prepared by fusion to determine SiO2,Al2O3,Fe2O3,TiO2,K2O,Na2O,CaO,MgO and S in pyrophyllite and kaolin,with results conforming to those obtained by chemical ...
