The present invention relates to a method for preparing high quality barium titanate powder by precipitating barium titanyl oxalate with spraying a mixture of an aqueous barium chloride and titanium tetrachloride (TiCl4) to an aqueous solution of oxalic acid via a nozzle in high speed, which exhibits improved yield with shortened reaction time and optimized stoichiometric mole ratio of barium to titanium, thus suitable materials for multilayer ceramic capacitors, PTC thermistors, resistors, and the like. |
