Abstract	The technique of hydrothermal stripping from mixed aqueous-organic systems is a promising method for synthexizing oxide ceramic powdcrs for high-performance applications.Some factors influcncing heterogeneous hydrothermal stripping with water from iron-loaded organic phase of naphthenic acid-isooctyl alcohol-kerosenc,such as initial concentrations of iron and naphthenic acid,concentration of Fe2O3“seed”,temperature and time,were investigated.Baseed on the experimental results,the rate equation was established.Nano-ferric oxide powders were obtained by the technique of hydrothermal stripping from the iron-loaded organic phase.The results suggest that the heterogeneous hydrothermal stripping proceeds in 3 steps:adsorption of naphthenic acid dimers and naphthenic complex of iron onto the surface of “seed”,hydrolysis of adsorbed complex of iron,and condensation of hydrolyzed complex.The process activation energy is 115kJ/mol and the heterogeneous hydrothermal stripping is controlled by a chemical reaction(the hydrolysis of naphthenic complex of iron).
