| Sažetak: | Заглавие с экрана The research work was carried out in the network of beryllium materials fluorineammonium processing technology development. According to this technology beryllium raw materials are processed by ammonium hydrofluoride at low temperatures. Fluorinated product then is dissolved in water, though only beryllium and silicon move completely in solution, aluminum and iron fluorine containing compounds partially pass in solution. To purify production beryllium solution from impurities the precipitation method by aqueous ammonia solution is provided. There are data of purification effectiveness in article, the degree of hydrolysis (precipitation) of impurities and beryllium are presented. Also the need to wash the precipitate, formed as a result of alkaline hydrolysis, in order to reduce the loss of beryllium is proved. |
