Abstract

La invención se refiere a un procedimiento para fabricar un óxido metálico simple o mezclado o un producto basado en óxido de silicio a partir de un relleno precursor que contiene uno o más precursores orgánicos. Los óxidos pueden ser, por ejemplo, óxidos de Ti, Al, Mg, Th, Si, Ba, Bc, Zr y similares. El procedimiento consiste en la puesta en contacto del relleno precursor metalo-orgánico con un medio reacción que comprende CO{sub,2} supercrítico a una temperatura de entre 31 y 100º C y a una presión supercrítica de entre 3 x 10{sup,7} y 5 x 10{sup,7} Pa para formar, a partir del precursor, un óxido metálico simple o mezclado o un producto basado en óxido de silicio; el procedimiento finaliza con la separación del óxido metálico simple o mezclado o del producto basado en óxido de silicio de la mezcla de reacción expandiendo el CO{sub,2} supercrítico hasta una presión inferior a la presión supercrítica.
