溴化锂含量影响X射线荧光光谱法测定滑石主、次元素的研究

摘要

Fused cast bead method was used to determine the major and minor elements contents in talc by wavelength dispersive X-ray fluorescence spectrometer (XRF). When fusing the samples and casting the beads, 10mg uncontaminated lithium bromide was added to the melt as releasing agent, in order to obtain mould release effect and more accurate determining results.%采用波长色散型X射线荧光光谱法中熔融玻片法测定滑石中的主、次元素含量，在制备熔融玻片样品时，选择10 mg无污染、脱模效率高的溴化锂做脱模剂，在取得好的脱模效果的同时使测试的元素氧化物含量结果更准确。
