摘　　要：采用Li2CO3+Li2B4O7(1+5)混合溶剂熔融萤石试样,选择最佳的熔融温度与熔融时间,减少了F、S元素的挥发损失;选择最佳的稀释比及最佳的仪器工作条件,提高了F、P、S等元素的分析灵敏度,荧光测定值与化学值相比,结果良好。The fluorite sample was prepared by fusion method with Li2CO3/Li2 B4O7 （1/5） as mixed solvent. With the optimal fusion temperature and melting time,the volatilization loss of fluorine and sulfur can be redueed. The analytical sensitivity of fluorine, phosphorus and sulfur can be improved under the selected dilution ratio and the running conditions. The results obtained by X ray fluoreseent spectrometry was satisfied compared with that by ehemical method.
