Abstract
A silicon halide such as silicon tetrafluoride is reacted with an agitated slurry of an alkali metal hydride such as sodium hydride in a liquid which includes a diaryl ether such as diphenyl ether. At elevated temperatures such as 250.degree.-260.degree. C., complete conversion of the silicon tetrahalide to silane is observed, even with contact times under two seconds.
