| titleOfInvention | Method for producing metal oxide powder |
| abstract | To provide a method for producing a metal oxide powder that is fine but excellent in dispersibility and has few impurities. An aqueous solution of a metal chloride salt is brought into contact with an aqueous ammonia solution to neutralize the metal chloride salt, thereby neutralizing the metal chloride salt containing a neutralized metal chloride salt and an ammonium salt. A metal chloride salt neutralization reaction step to obtain a slurry, and the ammonium salt is present in the metal chloride salt neutralization reaction slurry in an ammonium salt / metal element molar ratio of 0.8 to 4.4; The metal chloride salt neutralization reaction slurry is heated at 110 to 150 ° C. to dry the metal chloride salt neutralization reaction slurry and evaporate ammonia in the ammonium salt to neutralize the hydrochloric acid-containing metal chloride salt. A slurry of the hydrochloric acid-containing metal chloride salt neutralized product is prepared, and the hydrochloric acid-containing metal chloride salt neutralized product is washed at pH 4.5 to 7 to obtain a metal oxide. A washing step to obtain a powder; Method for producing a metal oxide powder which is characterized in that. [Selection figure] None |
