| titleOfInvention | Preparation method of barium carbonate and product prepared by same |
| abstract | The invention relates to a preparation method of barium carbonate and a barium carbonate product prepared by the same. The preparation method of the barium carbonate comprises the following steps: (1) adding barium hydroxide octahydrate crystals into an ice water bath, and mixing, wherein the temperature is controlled at 0-5 DEG C; (2) introducing carbon dioxide into the mixture obtained in the step (1) to react until the pH value of the reaction solution is 6.0-7.0; and (3) carrying out solid-liquid separation on the solid-liquid mixture obtained in the step (2), and drying the solid to obtain the large-specific-area high-purity barium carbonate product. The preparation method provided by the invention solves the problem of incompatible low strontium and large specific area in the existing preparation method, so that the barium carbonate product is no longer influenced by the sintering temperature, thereby enhancing the performance of the ceramic material. |
