ABSTRACT:
A process for the production of high purity silane by reacting silicon tetrafluoride exclusively with sodium aluminum tetrahydride, potassium aluminum tetrahydride, or a mixture of sodium aluminum tetrahydride and potassium aluminum tetrahydride, preferably in an inert liquid reaction medium comprising an ether. The inventive process is a highly advantageous and economical route to silane since it also produces valuable fluoride salt.
