Compositions involving V2O3-CaO

摘要

The present invention pertains to novel phases involving V2O3 and CaO and the method for their preparation. The solid compositions involving V2O3 and CaO fall on three vertical lines and within the shaded areas of four polygons in a binary composition diagram of V2O3 and CaO as shown in the drawing herein e.g., FIG. 1. The composition may be used as a catalyst for oxidation or reduction reactions.
