| titleOfInvention | A kind of preparation method of ruthenium dioxide for resistance paste |
| abstract | The invention discloses a preparation method of ruthenium dioxide for resistance paste, which comprises the following steps: (1), preparing a ruthenium chloride solution; (2), hydrolyzing; (3), aging; (4), washing with water; (5), calcination. In the preparation method of ruthenium dioxide for resistance paste of the present invention, the application of high-efficiency composite dispersant A in the hydrolysis process reduces the generation of powder agglomeration; suitable aging conditions, the use of dispersant B in the washing process, and the adjustment of pH , improve the washing efficiency, reduce the agglomeration and Ru loss during the washing process; optimize the calcination process to dehydrate the filter cake with water in a short time, and use the tension of the escape of water molecules to prevent the powder from secondary in the calcination process. After agglomeration, the dispersibility of the prepared ruthenium dioxide powder is good. The ruthenium dioxide powder prepared by the method for preparing ruthenium dioxide for resistance slurry of the present invention has uniform particle size and large specific surface area, and the prepared resistance slurry has narrow TCR width and good ESD performance. |
