<p>A method for manufacturing aqueous hydrides comprising a reaction which does not require precise stoichiometric proportions of metal, alkali hydroxide and water. Metal pieces (22) are added to tank (11). The specific gravity of the reaction mixture is monitored by hydrometer (21) and adjusted where appropriate during the reaction process. Temperature and rate of reaction are controlled to prevent formation of silicates. An apparatus system (10) which is suitable for carrying out the process includes a circulating reactor with a false bottom tank (11). An opening (12) in the tank (11) allows for release of steam during the reaction. Tank (11) also has an opening or drain (13) positioned at the bottom of tank (11). The apparatus also includes pump (14), mixer (16) and heat exchanger (17). Water source (18) and caustic source (19) provide for water and caustic.</p> |
