Abstract
Alkali metal borohydrides are prepared by a two-stage process wherein there is first prepared a mixture of an alkali metal hydride with an alkali metal borate and/or an alkaline earth metal borate, and/or magnesium borate. In this first step either the hydride or the borate component is prepared in situ, by reacting an alkali metal with hydrogen in the presence of a borate or by reacting an alkali metal oxide and/or alkaline earth metal oxide and/or magnesium oxide with boron oxide in the presence of an alkali metal hydride. In the second stage the alkali metal borohydrides are obtained by reacting the mixture obtained in the first stage with at least the stoichiometric amount of silicon dioxide in the presence of hydrogen. In the first stage the temperature is preferably 250-310 DEG C. and in the second stage 350-460 DEG C., in both cases hydrogen pressure is preferably 2-4 atmospheres. Specifications 859,468 and 871,569 are referred to.
