碱金属五硼酸盐的合成研究

Studies on the Syntheses of Alkalis Pentaborates

碱金属五硼酸盐是一种重要的化工原料,广泛应用于国民经济各个行业,因此合成不同的碱金属五硼酸盐具有重要的现实意义。文章总结了五硼酸锂、五硼酸钠、五硼酸钾、五硼酸铷和五硼酸铯的合成方法,着重介绍了其水合盐的合成条件和方法,阐述了各个方法的原理和应用前景,指出了合成碱金属五硼酸盐的发展趋势。

Alkalis pentaborates as the important chemical materials have been widely used in all industries of national economic construction. Therefore, it is of practical significance to synthe- size diffident alkalis pentaborates. Herein, the methods for synthesizing lithium pentaborate, sodi- um pentaborate, potassium pentaborate, rubidium pentaborate and caesium pentaborate are summa- rized in this paper. The synthetic principles, reaction condition and application prospects of the methods are also expatiated. Meanwhile, the development trend of alkalis pentaborates was also pointed out.
