Abstract

PIEZAS PRENSADAS DE DIOXIDO DE TITANIO FABRICADO POR VIA PIROGENA CON LAS SIGUIENTES CARACTERISTICAS FISICO-QUIMICAS: DIAMETRO EXTERIOR: 0,8 - 15 MM SUPERFICIE BET, SEGUN DIN 66 131: < 1 - 20 M2/G VOLUMEN DE POROS: 0,01 0,29 CM3/G DISTRTIBUCION DE LOS POROS: SIN POROS <10 NM, AL MENOS EL 90% DE LOS POROS EN EL MARGEN DE 10 - 80 NM RESISTENCIA A ROTURA: 30 - 500 N/PIEZAS PRENSADA COMPOSICION:> 99,5% TIO2 SE FABRICAN MEZCLANDO DIOXIDO DE TITANIO FABRICADO POR VIA PIROGENA CON UREA, GRAFITO Y AGUA. LA MEZCLA SE COMPACTA Y LA MASA OBNTENIDA SE SECA EVENTUALMENTE A 80 A 120 (GRADOS) C Y SE TRITURA. A CONTINUACION SE EXTRUSIONA O TRANSFORMA EN PASTILLAS Y LAS PIEZAS PRENSADAS OBTENIDAS SE TRATAN CON UNA TEMPERATURA DE 710 A 1000 (GRADOS) C DURANTE 0,5 A 6 HORAS. LAS PIEZAS PRENSADAS SE PUEDEN UTILIZAR COMO CATALIZADOR O SOPORTE DE CATALIZADOR.
