Abstract

Procedimiento para la preparación de mezclas aglomeradas de óxidos metálicos muy dispersos que constan de 1.) 30-95% en peso de óxido metálicos altamente dispersos preparados por hidrólisis a la llama, preferentemente ácido silícico altamente disperso o sus mezclas u óxidos mixtos, 2.) 5-70% en peso de agentes opacificadores inorgánicos que tienen por lo menos un máximo de absorción en el margen comprendido entre 1,5 y 10 /um, de entre el grupo de los óxidos inorgánicos y óxidos mixtos, carburos y nitruros, caracterizado porque el agente opacificador inorgánico se añade continuamente durante la preparación del óxido metálico en la proporción de mezcla pretendida a lo más tardar en el primer tercio de la instalación de aglomeración y de esta forma se incorpora por aglomeración en el óxido metálico.
