Abstract
Procédé de traitement d’une phase gazeuse résiduelle issue d’une technique CVI L’invention concerne le traitement d’une phase gazeuse résiduelle comprenant des chlorosilanes radicalaires issue d’un procédé d’infiltration chimique en phase vapeur de carbure de silicium, dans laquelle la phase gazeuse résiduelle est diluée dans une conduite de pompage de sorte à éviter le dépôt d’espèces pyrophoriques. Figure pour l’abrégé : Fig. 1.Process for treating a residual gas phase resulting from a CVI technique The invention relates to the treatment of a residual gas phase comprising radical chlorosilanes resulting from a chemical infiltration process in the vapor phase of silicon carbide, in which the residual gaseous phase is diluted in a pumping line so as to avoid the deposit of pyrophoric species. Figure for abstract: Fig. 1.
