Abstract
DTA and XRD studies of the Fe2V4O13–Cr2V4 O13 system have shown that continuous solid solutions of a Fe2–xCrxV4O13 type, bearing a Fe2 V4 O13 structure, are formed in the system. With the increasing degree of the Cr3+ ion incorporation into the Fe2 V4 O13 structure, a contraction of the solid solution crystal lattice develops. Solid solutions of a Fe2–x Crx V4 O13 type melt incongruently, their melting temperature increasing from 953 to 1003 K with increase in the degree of the Cr3+ ion incorporation. The solid product of melting Fe2–x Crx V4 O13 solid solutions for 0.2<x >1.2 is the Fe1–x Crx VO4 solution phase, and for x ≤0.2 and x ≥1.4 – the Fe1–x Crx VO4 phase as well as FeVO4 or CrVO4 , respectively.
