Processing of NaBH4 from NaBO2 with MgH2 by ball milling

Downloadable (with restrictions)! In this paper, NaBH4 is synthesized from NaBO2 and MgH2 under inert gas via ball milling, without applying high temperature or pressure. Developments in the recycling of NaBO2 will make NaBH4 usage more feasible. To obtain the optimum recycling conditions of NaBO2 with MgH2 via solid phase reaction under inert atmosphere, 3 sets of experiments were performed.
