Improvements in or relating to methods of producing high quality silicon characterized by a substantially pure silicon manufacturing process by the reaction of a solution of silicon tetrachloride with a liquid suspension of lithium aluminum hydride to produce silane and the subsequent thermal decomposition of the silane in which said reaction is carried out by adding the silicon tetrachloride to the lithium aluminum hydride in such an amount or at such a rate that an excess of lithium hydride is maintained in the mixture above that required for the complete chemical reaction with what the production as impurity in the diborane silane by any boron compounds present in the reactants is kept to a minimum.
