Abstract: A process for the preparation of a mono-disperse metal oxide material characterised in that it comprises hydrolysing an alkoxide in the presence of a solvent at a temperature and pH necessary to produce a sol and super-­ critically treating the sol with an extraction fluid and adequate agitation to produce a mono-disperse metal oxide is disclosed.
The present invention provides advantages over the prior art.
