Abstract

Procedimiento para la deshidratación completa y calcinación consecutiva de fluoruros hidratos de aluminio, caracterizado por la combinación de las siguientes fases de proceso: a) porque el fluoruro hidrato de aluminio se deshidrata en una primera fase hasta el fluoruro semihidrato de aluminio, A1F3.0.5H20, conforme el procedimiento ya conocido, y b) porque el fluoruro semihidrato de aluminio se libera en una segunda fase del agua cristalizada residual, mediante tratamiento en un horno giratorio horizontal caldeado indirectamente, y a continuación se calcina a unos 500 - 600ºC.
