Abstract

PROCESO DE DEPOSICION DE FASE DE VAPOR MODIFICADO. COMPRENDE UNA REACCION DE PRODUCCION DE VIDRIO PARA LA FORMACION DE UN VIDRIO DOPADO A PARTIR DE UN MATERIAL REACTANTE, INCLUYENDOSE UN PASO PARA IMPEDIR QUE SE PRODUZCA LA REACCION DE FORMADO DEL VIDRIO ANTES DE QUE EL MATERIAL REACTANTE HAYA SIDO CALENTADO A UNA TEMPERATURA MAYOR QUE LA REQUERIDA PARA LA REACCION DE FORMADO DEL VIDRIO, CON LO QUE SE OBTIENE LA PRODUCCION DE UN VIDRIO DOPADO DE UNA COMPOSICION IMPOSIBLE DE OBTENER, POR CONSIDERACIONES TERMODINAMICAS, CON UNAS TEMPERATURAS MAS BAJAS; EMPLEANDOSE COMO MATERIAL REACTANTE TRICLOROFLUORURO DE SILICIO (SICL3F), QUE ES CALENTADO A UNA TEMPERATURA EN LA QUE SE TIENE LA REACCION DE CAMBIO ENTRE ALGUNOS DE LOS TETRACLORUROS DE SILICIO Y EL REACTANTE QUE INCLUYE EL DOPANTE. TIENE APLICACION EN LA FABRICACION DE FIBRAS OPTICAS.
