METHOD FOR PRODUCING SPHERICAL MIXED OXIDE POWDERS IN A HOT WALL REACTOR

摘要

The invention relates to a novel method for producing spherical mixed oxide powders with at least two constituents in a hot wall reactor. By using aqueous or organic saline solutions or suspensions with a limited salt or solid concentration in conjunction with additives in the form of surfactants and/or inorganic salts characterised by an exothermic decomposition reaction, a compact spherical particle morphology can be obtained, the average particle size being between 5 nm and < 10 mum.
