Solid-state reactions between alkali persulfates and oxides of corundum structure

Thermal and X-ray diffraction investigations of the binary system chromium(III) oxide — barium perchlorate trihydrate

“…The oxide also catalyses the decomposition of alkali metal pyrosulphates to the sulphates through the formation of chromium sulphate or the double sulphates with the alkali metals [4]. Udupa and Srinivasan [5] recently reported that the oxide reacts with barium chlorate via complex stoichiometry to give barium chromate BaCrO4 and barium chloride.…”
