Abstract

LA PRESENTE INVENCION PRESENTA UN FILTRO PARA FUNDIDO CALIENTE METALICO QUE SE COMPONE DE UN MATERIAL CERAMICO POROSO CON UNA ESTRUCTURA EN RED TRIDIMENSIONAL Y CRISTALES PARECIDOS A AGUJAS DEPOSITADOS EN LA SUPERFICIE DE LA RED DEL MATERIAL CERAMICO POROSO, Y UN PROCESO PARA PRODUCIR UN FILTRO PARA FUNDIDO CALIENTE METALICO QUE CONSTA DE UN MATERIAL CERAMICO POROSO SINTETIZADO DE ESTRUCTURA EN RED TRIDIMENSIONAL SUMERGIDO EN UN COMPUESTO ACUOSO QUE CONTIENE UN MATERIAL COMPUESTO DE 15-80% EN PESO DE B2O3, 2-60% EN PESO DE AL2O3, 0-30% EN PESO DE CAO, 5-50% EN PESO DE MGO Y O-30% EN PESO DE SIO2. LUEGO SE SECA EL MATERIAL CERAMICO POROSO IMPREGNADO CON EL COMPUESTO ACUOSO SIGUIENDOLE UN QUEMADO PARA OBTENER UN MATERIAL CERAMICO POROSO QUE TIENE CRISTALES COMO AGUJAS DEPOSITADOS EN LA SUPERFICIE. EL FILTRO PUEDE PREVENIR LA CONTAMINACION DEL FUNDIDO CALIENTE METALICO (EJ. FUNDIDO CALIENTE DE ALUMINIO). TIENE FILTRABILIDAD MAYOR QUE LA DE UN FILTRO FABRICADO SOLAMENTE DE UN MATERIAL CERAMICOPOROSO Y POSEE UNA VIDA MAS LARGA QUE LA DEL FILTRO MENCIONADO.
