ChemInform Abstract: Synthesis and X-Ray Characterization of Double Oxides of the Formula Cr1-xW1+xO4.
ChemInform Abstract
The mixed valency compounds of title are prepared by solid state reactions at 1300 °C. Depending on x, three phases are identified by XRD: a phase with rutile-type structure for 0.4 ≤ x ≤ 0.50, and two others with rutile-related structures (CrWO4-type for 0 ≤ x ≤ 0.25 and WO2-type for 0.80 ≤ x ≤ 1).
