Abstract

UN PROCEDIMIENTO PARA LA PREPARACION DE LOS TITANATOS EN FORMA DE PARTICULAS ESFERICAS. TITANATOS DE BARIO, ESTRONCIO, O BARIO Y ESTRONCIO MEZCLADOS CONSTITUIDOS ESENCIALMENTE POR PARTICULAS ESENCIALMENTE SOLIDAS, NO AGREGADAS, QUE TIENEN DIAMETROS QUE OSCILAN ENTRE 0,05 Y 1 MICRA Y UNA DISTRIBUCION GRANULOMETRICA MUY ESTRECHA EXPRESADA POR EL INDICE DE POLIDISPERSION DW/DN H 1,20, EN DONDE DW ES EL DIAMETRO DE PESO MEDIO Y DN ES EL DIAMETRO DE NUMERO MEDIO, SIENDO DICHAS PARTICULAS PERFECTAMENTE ESFERICAS CON UNA RELACION AXIL MEDIA TOTAL POR LO MENOS SUPERIOR O IGUAL A 0,930; PREPARANDOSE DICHOS TITANATOS CON UN PROCEDIMIENTO QUE PROPORCIONA LA PRECIPITACION DE UN PRECURSOR PEROXIDICO QUE TIENE LAS CARACTERISTICAS MORFOLOGICAS DE LOS TITANATOS, OBTENIDO POR CALENTAMIENTO DE UNA SOLUCION ALCALINA QUE COMPRENDE UN COMPLEJO DE UN COMPUESTO DE TITANIO CON UN COMPUESTO PEROXIDICO, UN COMPUESTO DE M2B ELEGIDO ENTRE BA, SR, O SUS MEZCLAS Y UN COMPUESTO CAPAZ DE ACOMPLEJAR EL ION DE M2B Y APTO PARA OXIDARSE MEDIANTE EL COMPUESTO PEROXIDICO BAJO LAS CONDICIONES DE REACCION, DANDO LUGAR A PRODUCTOS DE DESCOMPOSICION SOLUBLES Y DE MODO QUE PROPORCIONEN UNA PRECIPITACION HOMOGENEA DEL PRECURSOR PEROXIDICO QUE COMPRENDE TIANIO Y M2B, Y CALENTANDO SUBSIGUIENTEMENTE EL PRECURSOR A TEMPERATURAS NO INFERIORES A 100JC Y DE MODO QUE NO OBSTANTE SE OBTENGA EL TITANATO CORRESPONDIENTE CON LAS CARACTERISTICAS MORFOLOGICAS ANTES INDICADAS.
