Formation of impurity Si2OH6 in silane synthesized from silicon tetrafluoride

The possibility of the reduction of hexafluorodisiloxane by calcium hydride in the synthesis of silane from silicon tetrafluoride has been studied. This reaction is shown to be not decisive for oxygen contamination of silane. The most likely reason for the appearance of impurity Si2OH6 in "fluoride" silane is the Ca(OH)2-catalyzed reaction of silane with trace water. The concentration of impurity Si2OH 6 in silane at the stage of synthesis may be efficiently decreased by the preliminary purging of calcium hydride with a hydrogen (grade A) flow.
