| titleOfInvention | A kind of ammonium dichromate and sodium sulfate mixed crystal and its preparation method and application |
| abstract | The invention provides a mixed crystal of ammonium dichromate and sodium sulfate and its preparation method and application. The preparation method comprises: dissolving ammonium sulfate and heating up, and then adding sodium dichromate, wherein sodium dichromate and ammonium sulfate The molar ratio of the mixture is 1:(0.9-1.1). After stirring and reacting, it is evaporated, concentrated, cooled and crystallized to obtain mixed crystals; the mixed crystals are used to prepare chromium oxide green pigments. In the present invention, through the control of the adding method and ratio of the reactants, the reaction and the post-treatment process, mixed crystals with uniform particle size, dispersion and non-bonding are prepared, the generation of double salts is avoided, and the composition of the mixed crystals is guaranteed to meet the requirements; At the same time, the preparation process of the mixed crystal is short, the process conditions are easy to control, and the transportation problem of ammonium dichromate is avoided; the chromium oxide green pigment is prepared with the obtained mixed crystal, which can effectively solve the problem of difficult feeding in industrial production. The resulting product has better chromaticity parameters and excellent performance. |
