Reaction of water with alkaline-earth stabilized bismuth(III) oxide

The reaction of water with various compositions of calcium, strontium and barium-stabilized bismuth sesquioxide has been examined. X-ray diffraction, TGA, DTA and optical studies were used. The reaction of water with these oxides occurs at room temperature and forms a new, low-temperature, single-ph...

Description
Summary:The reaction of water with various compositions of calcium, strontium and barium-stabilized bismuth sesquioxide has been examined. X-ray diffraction, TGA, DTA and optical studies were used. The reaction of water with these oxides occurs at room temperature and forms a new, low-temperature, single-phase material. The speed of the reaction is particle-size dependent. The water-containing phase can be decomposed back to the rhombohedral-stabilized structure at temperatures between 400 and 700°C. It appears that the reaction is an intercalation-type process with pronounced exfoliation.
