Abstract
The present invention relates to a method for producing tetrahydridoborate salts with high efficiency at low cost. The method for the production of metal borohydride salts according to the present invention comprises the steps of providing an anhydrous metal borate salt and milling the anhydrous metal borate salt in the presence of a metal material based on magnesium or magnesium alloys in a hydrogen atmosphere at a temperature and for a time sufficient to produce the metal borohydride salt. In another embodiment of the invention, the method for the production of metal borohydride salts according to the present invention comprises the steps of providing an hydrated metal borate salt and milling the hydrated metal borate salt in the presence of a metal material based on magnesium or magnesium alloys in an inert gas atmosphere at a temperature and for a time sufficient to produce the metal borohydride salts. In a still further embodiment of the invention, the metal material based on magnesium or magnesium alloys is a secondary magnesium material, preferably a Class 2, Class 3, or Class 6 secondary magnesium material.
