This invention relates to a method of manufacturing a product based on a simple or mixed metal oxide, or silicon oxide, from a charge of one or more precursors comprising one or more organic precursors. These oxides can be, for example, oxides of Ti, Al, Mg, Th, Si, Ba, Bc or Zr etc. The method comprises bringing the charge of organo-metallic precursors into contact with a reaction medium that comprises supercritical C02, at a temperature of from 31 to 100° C. and a supercritical pressure of from 3×107 to 5×107 Pa, in order to form from the precursor, a product based on a simple or mixed metal oxide, or silicon oxide, from the reaction medium by reducing the pressure of the supercritical C02 to a pressure lower than the supercritical pressure.
Method of manufacturing a product based on a simple or mixed metal oxide, or an oxide of silicon, from a charge of precursor(s) comprising one or more organo-metallic precursors, said method comprising the step of bringing the charge of precursor(s) into contact with a reaction medium comprising supercritical CO2, at a temperature of 31 to 100° C. and a supercritical pressure of 107 to 5×107 Pa, reacting said charge of precursor(s) in said reaction medium to form a product based on a simple or mixed metal oxide, or an oxide of silicon;
