摘　　要：本文研究了应用 ICP- AES法测定硅酸盐元素分析中 L i BO2 与样品熔融后玻璃熔珠的酸溶解中出现沉淀的问题 ,并就其熔珠加热出现的沉淀进行了 X射线能谱元素分析 ,并且讨论了解决出现白色沉淀的方法。The problem of white precipitate after acid dissolution of glass bead (LiBO 2∶sample) in determination of silicate was discussed.When glass bead heated it had some white precipitate.The element in white precipilate was also analyzed by EPMA.The result shows that element is Si only.The method is discussed solving white precipitate.
