| Phase relationships in binary systems Cs2Mo2O7 - Nb2O5 (Ta2O5) are studied using differential thermal and Xray
phase analyses. Incongruent melting (in the system with Nb2O5 ) and congruent melting (in the system with
Ta2O5 ) compounds of compositions CsNbMoO6 and CsTaMoO6 are shown to be formed. Polymorphic transformations
occur in both compounds. The enthalpies of melting and polymorphic transformation of the compounds found
have been estimated. |
