摘要 以无水四硼酸锂和碳酸锂作熔剂,采用玻璃熔片法制样,建立了测定铝硅锆质耐火材料中Al2O3,SiO2,Fe2O3,TiO2,CaO,MgO,ZrO2,HfO2等组分的X射线荧光光谱法(XRF)。根据铝硅锆质耐火材料中主次成分含量范围,采用标准样品配制出被测组分具有合适含量范围和浓度梯度的校准样品绘制校准曲线。并对熔剂选择、基体效应校正进行了探讨。将X射线荧光光谱法用于铝硅锆质试样的分析与化学分析结果进行比对,两者吻合。 A method has been developed for rapid analysis of ZrO2,HfO2,Al2O3,SiO2,Fe2O3,TiO2,CaO,MgO,etc.in alumina-silica-zironia refractory by X-ray fluorescene spectrometry.The sample was made into fused glass pellet with a mixture of Li2B4O7 and Li2CO3 as fluxing agent.According to the concentration range of each component,the calibration sample was prepared using the certified reference standard sample with concentration near to the tested component.The calibration curves were drawn by testing these calibration samples.The selection of fluxing agent,the calibration of matrix effects and the conditions of fusion are discussed.The test results of this method were closely matched with those of chemical method.
