  Fine Purification of Monoisotopic Silanes²⁸SiH₄ ,²⁹SiH₄ , and³⁰SiH₄via Distillation

  摘要：

  High-purity isotopically enriched (99.98% Si-28, 99.57% Si-29, and 99.83% Si-30) silane samples are prepared for the first time. The total hydrocarbon content of the samples is no higher than 0.1-0.3 ppm. The concentration of electroactive impurities in the silicon prepared from the purified monoisotopic silane is below 10(15) cm(-3).

  Formation of impurity Si2OH6 in silane synthesized from silicon tetrafluoride

  摘要：

  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 Si2OH6 in silane at the stage of synthesis may be efficiently decreased by the preliminary purging of calcium hydride with a hydrogen (grade A) flow.
