Method for producing inorganic oxide particles
摘要:
The present invention relates to a method for producing inorganic oxide particles, comprising at least the following steps of: coagulating a dispersion obtained by carrying out the hydrolysis reaction and the polycondensation reaction of a metal alkoxide in the presence of a basic catalyst; filtering the dispersion to obtain particles; and drying the particles, wherein the step of coagulating the dispersion is carried out by adding a coagulant comprising at least one compound selected from the group consisting of carbon dioxide, ammonium carbonate, ammonium hydrogen carbonate and ammonium carbamate to the dispersion. The inorganic oxide particles obtained by the method of the present invention have high purity and are excellent in flowability.
