Processing of NaBH4 from NaBO2 with MgH2 by ball

In this paper, NaBH 4 is synthesized from NaBO 2 and MgH 2 under inert gas via ball milling, without applying high temperature or pressure. Developments in the recycling of NaBO 2 will make NaBH 4 usage more feasible. To obtain the optimum recycling conditions of NaBO 2 with MgH 2 via solid phase reaction under inert atmosphere, 3 sets of experiments were performed.

Effect of atmosphere on the mechanical milling of

2000-1-1 · Fig. 1 shows the changes in the measured BET surface area with milling time for natural graphite milled in a planetary mill in various atmospheres. The specific surface area of samples milled in an inert atmosphere increased rapidly, from 6 m 2 /g to above 150 m 2 /g within 3 h of milling. However, this increase subsides after 10 h of milling as agglomeration sets in.

Ball Mills an overview ScienceDirect Topics

The ball milling process is carried out for approximately 100–150 h to obtain uniform-sized fine powder. In high-energy ball milling, vacuum or a specific gaseous atmosphere is maintained inside the chamber. High-energy mills are classified into attrition ball mills, planetary ball mills, vibrating ball mills, and low-energy tumbling mills
