Abstract

Procedimiento autotérmico continuo para la producción de trifluoruro de aluminio de alta pureza, caracterizado por el hecho de que la alúmina parcialmente deshidratada se introduce en un estado caliente en un reactor de lecho fluido precalentado, en el que se pone en contacto con vapores de HF sobrecalentados.
