Potassium tetrahydroborate

The second processing step consisted of salt decomposition with the subsequent reduction to pure metal. The method of chemical deposition of metal salts from the water salt solution with the subsequent reduction to pure metal by liquid phase reducer has been applied to prepare graphite-tin CMs. In this case tin chloride was used for impregnation and potassium tetrahydroborate was used as liquid phase reducer.

Volatile hydrides may be prepared from ether solutions by the reaction of the appropriate chlorides with lithium tetrahydroaluminate. In this general method, it is necessary to work with strictly anhydrous reagents and solvents because of the great reactivity of lithium tetrahydro-aluminate toward water. The procedures described below are believed to be much more convenient because the reducing agent employed is potassium tetrahydroborate, which is relatively insensitive toward water. Since only aqueous solutions are involved, there are no solvent-purification steps and there is no dissolution or contamination of stopcock grease, etc.
