Barium bromide
基本信息
应用 | Barium bromide is a precursor to chemicals used in photography and to other? bromides. Barium bromide was used to purify radium in a process of fractional crystallization devised by Marie Curie. Since radium precipitates preferentially in a solution of barium bromide, the ratio of radium to barium in the precipitate would be higher than the ratio in the solution. |
