| titleOfInvention | Method of obtaining rubidium and cesium |
| abstract | FIELD OF THE INVENTION chemistry, in particular to methods for producing rubidium sulphate and cesium sulphate. The purpose of the invention is to increase the yield of the product while increasing its purity. C-alumina (potassium alumina) alum is mixed with calcium oxide in a molar ratio of 1: (1.5-1.8). The mixture is heated to 150-300 ° C. The obtained spec is treated with water, filtered and washed with water. The filtrate and the washings are evaporated to dryness. The yield exceeds 95% of theoretical, the aluminum content does not exceed 0.2 wt.%. 2 tab. |
