硅酸盐试样的分解方法历来是分析工作者探索的重要课题。六十年代以来的硅酸盐分析出现了两种特别受到重视的分解方法:一是在密闭的条件下用矿物酸进行封闭溶样;二是用含锂硼酸盐进行熔融。两种方法各具千秋,但后者更为重要,应用也远为广泛。 Ingamells(1964)首先公开报导偏硼酸锂(LiBO_2)是一种非常有效的熔剂。稍后(1966),他在硅酸盐快速分析中应用LiBO_2熔样获得了成功。于是,含锂硼酸盐引起了硅酸盐分析者的强烈兴趣,发表的文献已在百篇以上,在硅酸盐快速分析中发挥了重要的作用。本文考虑到这类熔剂的广阔应用前景,特对
The decomposition of silicate samples has traditionally been an important topic explored by analytical workers. Two silicate analyzes since the 1960s have emerged as two particularly important methods of decomposition: first, closed-sample dissolution with mineral acids under confined conditions; second, melting with lithium-containing borates. Both methods have their advantages and disadvantages, but the latter is even more important and the application is far broader. Ingamells (1964) first reported publicly that lithium metaborate (LiBO 2) is a very effective flux. Later (1966), he succeeded in applying the LiBO 2 melt in the rapid silicate analysis. As a result, lithium-containing borates have generated a strong interest among silicate analysts and published more than a hundred articles, playing an important role in rapid silicate analysis. This article takes into account the broad application of such flux prospects, special
