| titleOfInvention | By the malonate method, the preparation method of the precursor of metal oxide |
| abstract | In preparing powders of metal oxides using maronic acid as fuel, the oxidation of maronate anions by nitrate anions must be suppressed during the preparation of the precursors of the metal oxides. The present invention relates to a method of preparing a precursor of a metal oxide in applying a nitrate anion-maronic acid-ammonium hydroxide system to prepare a powder of the metal oxide. The following two methods are proposed as a method of inhibiting oxidation. One method was to form a precipitate of maronate salt in an initial aqueous solution containing all of the starting materials, and the other was to remove excess water present in the initial aqueous solution while heating under vacuum. The heating temperature of the initial aqueous solution was determined by the degree of vacuum. By applying these methods to produce a precursor of a metal oxide, it is possible to shorten the time for preparing the precursor, to produce a precursor having reproducibility, and to prepare a large amount of precursor. |
