摘要：

Phase relations in the solid state in the FeVO4-Co3V2O8 system, in the whole range of components concentration have been studied. It was found that the composition of the phase of the howardevansite type structure, formed in the investigated system, corresponds with the Co2.616Fe4.256V6O24 formula. The phase of the lyonsite type structure has a homogeneity range with the Co3+1.5xFe4-xV6O24 formula (0.476 < x < 1.667). The melting temperature and the volume of the unit cell of the lyonsite type structure phase increases together with the rise of cobalt quantity contained in it. Basing on the results of the DTA and XRD measurements a phase diagram of the FeVO4-Co3V2O8 system up to the solidus line was constructed.
