Abstract
Drying sodium borohydride dihydrate particles in a flowing stream of a chemically inert drying gas results in novel nearly odor-free, dust-free sodium borohydride particles which are free flowing without the need for anti-caking or flow additives. The dihydrate particles are preferably dried in a fluidized bed formed with a flowing stream of nitrogen.
