Abstract

PIEZAS PRENSADAS A BASE DE DIOXIDO DE TITANIO OBTENIDO PIROGENICAMENTE CON LAS SIGUIENTES CARACTERISTICAS FISICO- QUIMICAS: DIAMETRO EXTERIOR 2 A 15 MM SUPERFICIE BET (SEGUN 35 A 65 M (AL CUADRADO) /G DIN 66 131) VOLUMEN DE POROS 0,3 A0,8 M3/G RESISTENCIA A ROTURA 40 A 300 N DISTRIBUCION DE POROS NINGUN PORO DE DIAMETRO INFERIOR A 10 NM; AL MENOS EL 80% DE LOS POROS TIENE UN DIAMETRO DEL ORDEN DE 10 A 70 NM. COMPOSICION AL MENOS EL 94% DEL PESO DE TIO2 (MAYORMENTE, ESTO ES >50% DEL PESO DE ANATASA), EL RESTO ES SIO2 Y AL2O3. SE PRODUCEN MEZCLANDO Y COMPACTANDO DIOXIDO DE TITANIO OBTENIDO PIROGENICAMENTE CON UN PORIFICADOR, COMO, POR EJEMPLO, UREA Y CON AGUA; EN SU CASO, ADEMAS CON UN AGLOMERANTE, COMO POR EJEMPLO CAOLIN, CON UN FORMADOR DE TABLETAS, COMO, POR EJEMPLO, CERA. LA MASA OBTENIDA SE SECA A UNA TEMPERATURA DE 80 A 120 (GRADOS) C Y SE MACHACA PARA FORMAR UN POLVO. CON UN DISPOSITIVO YA CONOCIDO SE COMPRIME EL POLVO PARA FORMAR LAS POIEZAS PRENSADAS, LAS CUALES SON TEMPLADAS A UNATEMPERATURA DE 400 A 600 (GRADOS) C POR UN ESPACIO DE TIEMPO DE 0,5 A 4,5 HORAS. LAS PIEZAS PRENSADAS ENCUENTRAN APLICACION COMO PORTADORES DE CATALIZADOR O COMO CATALIZADOR.
