PROCESS FOR PRODUCING ELECTROCONDUCTIVE INORGANIC OXIDE PARTICLES AND ELECTROCONDUCTIVE INORGANIC OXIDE PARTICLES PRODUCED BY THE PROCESS

摘要

An object of the present invention is to provide a conductive inorganic oxide powder that is more fine and reduced in powder resistivity than a conventional conductive inorganic oxide powder. In order to achieve the object, the present invention adopts a method for manufacturing conductive inorganic oxide particles in which conductivity is furnished by doping a dopant metal component into the inorganic oxide particle where a step A through a step D described below are carried out in manufacturing of the conductive inorganic oxide particles. Prepare an inorganic oxide particles-containing slurry which contain the inorganic oxide particles (step A), the inorganic oxide particles-containing slurry which is made to contain a dopant metal component and an electrolysis method is carried out for electrolytic doping to dope a dopant metal component into the inorganic oxide particles by using a electrolytic doping unit 1 (step B), filtering and drying the slurry after finishing the electrolytic doping and collect particles by filter (step C), and firing the particles collected by filter to obtain conductive inorganic oxide particles (step D).
