Abstract: | Preparation of new solid solutions containing divalent europium have been tried in the systems Eu2Nb2O7Sr2Nb2O7 and Eu2Ta2O7Sr2Ta2O7. These solid solutions described as Eu2xSr2(1?x)M2O7 (M = Nb and Ta) exist in a pure orthorhombic phase in a limited region of x from 0 to about 0.5. The compounds with compositions close to Eu2M2O7 exist but techniques have not been found to prepare them in pure form. |
