The alkali-rich portion of the K/sub 2/O-- V/sub 2/O/sub 5/ system was invest igated by the reaction of various potassium oxo-compounds with vanadium pentoxide. The compounds KVO/sub 3/, K/sub 32/V/sub 18/O/sub 61, K/sub 4/V/sub 2/ O/sub 7/, and K/sub 3/VO/sub 4/ were established. Both oxidations and dispropontionations were observed for the K/sub 2/O- VO/sub 2/ system, and a new compound KVO/sub 2/ was found in the reaction of equimolar mixtures of the monoxide K/sub 2/O and vanadium dioxide. The lower oxides of vanadium and vanadium metal were oxidized by potassium monoxide to the vanadate K/sub 3/VO/sub 4/. The reactions of potassium monoxide are compared with those of sodium oxide for the same stoichiometry. (auth)
