【摘要】 采用熔融玻璃片法制样,X射线荧光光谱法测定钛铁矿中Fe、Ti、Si、Al、Ca、Mg、Mn、P、S、V和Cr等11种主次量组分。探讨了熔融钛铁矿的有效熔剂,认为Ii₂B₄O₇和Li₂CO₃混合熔剂效果好。方法用于钒钛磁铁矿等国家一级标准物质的测定,结果与标准值相符,对主、次量组分方法精密度（RSD,n=10）为0．20%～9．10%。更多还原

【Abstract】 A method for the determination of Fe,Ti,Si,Al,Ca,Mg,Mn,P,S,V and Cr in ilmenite samples by X-ray fluores- cence spectrometry with fusion sample preparation technique has been developed.The effect of different fusion regents on sample preparation are studied and mixed fusion reagent of Li₂B₄O₇-Li₂CO₃ is proved to be more effective.The method has been applied to the determination of these elements in National Standard Reference magnetite samples and the results are in agreement with certified values.The precision of the method is 0.20%～9.10% RSD（n=10）for the major and minor elements.更多还原
