中文摘要: 采用熔融制样,以钾长石、钠长石国家标准样品为主,辅以粘土、炉渣、硅石等标准样品,配制成一系列校准标样,用X射线荧光光谱法测定钾长石和钠长石中的Na2O、Al2O3、SiO2、K2O、CaO、Fe2O3、TiO2的含量,结果表明:方法的相对标准偏差为0.065%~2.9%,其测定结果与标准值基本一致,准确度好,可替代湿法化学分析,适合于长石类硅铝酸盐矿物的日常分析。

Abstract:In this paper, the contents of Na2O, Al2O3, SiO2, K2O, CaO, Fe2O3 andTiO2 in potassium and sodium feldspar were determined by XRF. Samples were prepared by fusion method. A series of standard solutions for calibration were prepared mainly with the national standards of potassium and sodium feldspar and supplementary with clay, slag and silica standards. The results show that standard deviation of this method is 0.065%~2.9%, which is basically consistent with the standard value. This method, due to its better accuracy, can be used as a routine method for analyzing feldspar-like aluminosilicate minerals and replace the wet chemical analysis method.
