PCT No. PCT/EP94/00587 Sec. 371 Date Sep. 5, 1995 Sec. 102(e) Date Sep. 5, 1995 PCT Filed Mar. 1, 1994 PCT Pub. No. WO94/20203 PCT Pub. Date Sep. 15, 1994A method of producing spherical particles made from inorganic oxides by sol/gel conversion in which a sol is sprayed upwards from below into a reaction zone containing a reactant gas in such a way that the sol does not split up into individual droplets until immediately before or as it enters the reaction zone, and the resulting droplets fly through the reaction zone along a curved trajectory during which they are presolidified, the presolidified droplets being caught in a trap. Also described are spherical particles made from inorganic oxides with a narrow pore diameter distribution and a high resistance to wear which are suitable for use as catalysts, catalyst supports, adsorbents drying agents or ion exchange materials.
