Interaction of chromato-molybdates of alkali metals with chromium (3) oxide

The results are presented of a study of interaction in the systems M2CrO4 x MoO3 - Cr2O3 and Cs2CrO4 x 2MoO3 - Cr2O3, where M stands for Na, K. The phase diagrams of the systems M2CrO4 x MoO3 - Cr2O3, (where M stands for Na, K) are plotted. Binary chromate-molybdates of sodium and potassium with chromium of the composition M3Cr(CrO4 x MoO4)sub(1,5), which melt incongruently, and also a binary chromate-molybdate of cesium and chromium of the composition CsCr/(CrO4)sub(0,5)/ have been obtained, and some of their physicochemical properties investigated
