摘要
A method for direct synthesis of sodium borohydride by solid-phase ball milling, which is performed by performing solid-phase ball milling on a mixture of a reducing agent and a material to be reduced using a ball mill under room temperature conditions. Get. The reducing agent includes at least one of magnesium, magnesium hydride, aluminum, calcium, and magnesium silicide. The material to be reduced is sodium metaborate containing crystal water, or sodium metaborate, or a mixture of sodium metaborate and sodium metaborate containing crystal water. Solid phase ball milling is performed in a mixed atmosphere of argon and hydrogen, or in an argon atmosphere or a hydrogen atmosphere. The method is simple in manufacturing process, controllable reaction process, mild reaction conditions, low energy consumption, low cost, high production volume, no pollution, safe, industrial production There is an advantage that is easy to do.
