Abstract
Improved sodium borohydride powder compositions have a silica-based anticaking agent. In a method wherein a mixture of sodium borohydride and an anti-caking agent are compacted under pressure, the process is improved, particularly in speed, by the use of a silica-based anti-caking agent.
Claims13
A composition consisting essentially of sodium borohydride and a silica-based anticaking agent comprising at least about 90 percent by weight silica at a level of between about 0.05 and about 2 weight percent relative to the sodium borohydride.
In a method of producing compacted sodium borohydride comprising admixing a composition consisting essentially of powdered sodium borohydride with powdered anticaking agent and compacting said mixture under pressure, the improvement comprising said anticaking agent being at least about 90% by weight silica and used at a level of between about 0.05 and about 2 weight percent relative to the sodium borohydride, whereby substantially enhanced production rates are achieved.
