Abstract
Powder X-ray diffraction and microscopy have been used to study phase ratios of the M2O-V2O5-SO3 (M = Rb, Cs) systems, which model the active component of rubidium-vanadium and cesium-vanadium catalysts for sulfuric acid production at high sulfur dioxide conversions. We have stated that each system forms four compounds: M3VO2(SO4)2, MVO2SO4, M4V2O3(SO4)4, and MVO(SO4)2. The thermal properties of these compounds and their interaction with water vapor saturated at room temperature have been studied. The unit cell parameters have been determined for the compounds MVO2SO4 (M = K, Rb), MVO(SO4)2, and M[VO2(SO4)(H2O)2] · H2O (M = Rb, Tl). The reciprocal transformations of the components and phases of the M2O-V2O5-SO3 systems match the Lux-Flood ideas of the acid-base properties of oxide compounds.
