Phosphors for catidolyscine l 1, their screens prepared on solarium, were suggested earlier. The lack of these Lomino (k) moss was poor stability and lack of;; The brightness of the settlement is due to the presence of a small number of honest chips in iMgFv.

При получении MgFj из вод ных растворов ,:ностыо илоавитьс от этих соединений не удаегс . Дл удалени следов последних из MgF, или cMeceii фторидов, содержащих эту соль (например, смеси MgFo, KF, ZnF.j и MnF.,), предлагае 1с следуюи1ий снособ.When MgFj is obtained from aqueous solutions, the reaction from these compounds does not succeed. To remove traces of the latter from MgF, or cMeceii fluorides containing this salt (for example, mixtures of MgFo, KF, ZnF.j and MnF.,), Suggest the following removal method.
Фтористый магний (или соответствующую смесь (i1оридов) фюрируют фтористы.м кадмием, вз тым в количестве от 3 до 30,и от веса MgF.j, в нейтрально или восстановительной среде при 700-1200°. Лучшие результаты получаютс в восстановительной среде при те.мпературе 900 - 1100.Magnesium fluoride (or the appropriate mixture (i1) of the species is fluorinated with fluoride.m. cadmium, taken in an amount of from 3 to 30% and by weight of MgF.j, in a neutral or reducing medium at 700-1200 °. The best results are obtained in a reducing environment with those The temperature of 900 - 1100.
