Abstract

PIEZAS PRENSADAS A BASE DE DIOXIDO DE SILICIO OBTENIDO PIROGENICAMENTE CON LAS SIGUIENTES CARACTERISTICAS FISICO - QUIMICAS: DIAMETRO EXTERIOR 2 A 15 MM SUPERFICIE BET 50 A 400 M (AL CUADRADO) /G VOLUMEN DE POROS 0,6 A 1,3 ML/G RESISTENCIA A LA ROTURA 40 A 120 N DISTRIBUCION DE POROS NINGUN PORO CON DIAMETRO INFERIOR A 5 NM; AL MENOS EL 80% TIENE UN DIAMETRO ENTRE 5 Y 40 NM. COMPOSICION >95% DEL PESO SIO2; RESTO, AL2O3. SE PRODUCEN COMPACTANDO DIOXIDO DE SILICIO OBTENIDO PIROGENICAMENTE CON CAOLIN Y/O GRAFITO, AZUCAR, ALMIDON, UREA, CERA, BAJO ADICION DE AGUA. ESTO SE SECA A UNA TEMPERATURA DE 80 A 120 (GRADOS) C, MACHACANDOSE A CONTINUACION PARA FORMAR UN POLVO. ESTE POLVO SE COMPRIME PARA FORMAR LAS PIEZAS PRENSADAS Y SE TEMPLA DURANTE 0,5 A 6 SEGUNDOS A UNA TEMPERATURA DE 400 A 1200 (GRADOS) C. LAS PIEZAS PRENSADAS SE PUEDEN USAR COMO PORTADORES DE CATALIZADOR O COMO CATALIZADOR.
