Abstract (en)
[origin: WO8303244A1] A method for the selective removal of boron halides and other Lewis acid-type impurities from silicon halides. Treatment of contaminated silicon halides with siloxanes, which react with the impurities, allow the distillation of silicon halide which is virtually free from contamination within extremely low limits of detectability.
