概要

Phase relations in the <special>VxMo1-xO2</special> system were investigated by a powder X-ray diffractometry for samples quenched from 1373K. The results are shown in Fig. 4 together with those reported by Marinder. Two types of crystal structures were found in this system. One was <special>MoO2-type(M1)</special> and another was rutile-type (R) structure. Boundary of <special>M1</special> and R was estimated as x=0.32 by X-ray diffraction patterns of the samples (Fig.1). At x=0.20, two phases with same <special>MoO2-type</special> structure coexisted, and two-phase region was estimated as 0.18≦x≦0.22(Fig.2). Lattice parameters for <special>M1</special> and R are illustrated as functions of composition in Fig.3. Variation of c-parameter in R was explaned by the cation distribution in the <special>VxMo1-x O2</special> and interaction of d-electrons in the cations.
