Description

Processes of interaction between MgO and EuF3 are studied. Results of these processes are formation of magnesium fluorides and europium(III) oxyfluorides of variable composition. It is determined that there is considerable difference in spectra of diffusion reflection of fluoride and oxyfluoride phases of Eu(III). Effect of silicon and deep vacuum on systems containing oxide phase is studied. It is determined that in such system presence of Eu(II) compounds are observed. Fundamentally different character of thermogravimetric curves is detected in the MgF2-EuF3-Si and MgO-EuF3-Si systems. That permits to propose the method of MgO content estimation in MgF2

Abstract (Russian)

Изучены процессы взаимодействия между MgO и EuF3, в результате которых образуются фторид магния и оксифториды европия(II) переменного состава. Установлено существенное различие в спектрах диффузионного отражения фторидной и оксифторидных фаз Eu(III). Изучено влияние кремния и глубокого вакуума на системы, содержащие оксидную фазу. Для этих систем установлено наличие соединений Eu(II). Установлен принципиально различный характер термогравиметрических кривых в системах MgF2-EuF3-Si и MgO-EuF3-Si, что позволило предложить способ оценки содержания MgO в MgF2
