Abstract

Hydrogen can be absorbed in amorphous boron during mechanical milling carried out under a hydrogen atmosphere, mainly in the form of B-H terminal and B-H-B bridge bonds. By a combination of IR absorption and thermal analyses, the desorption behavior of these two B-H bond states was clarified. For the sample mechanically milled for 80 h, the approximate ratio of the hydrogen trapped by terminal and bridge bonds is 1:2.
