摘　　要：对FeO-V2O5二元系通过XRD试验进行物相分析,理论计算中间化合物的热力学参数,并建立了溶液热力学模型,结合FACT软件计算绘制出FeO-V2O5二元系相图,通过DSC试验和XRD试验验证相图。此体系相图由三个共晶反应组成并且生成两种中间化合物反式尖晶石Fe2VO4和钒酸铁FeVO4,试验的结果对理论计算出的相图有很好的验证。The compounds of FeO-V2O5 binary system were analyzed through X-ray diffraction experiment. The thermodynamic data of these compounds and solution model were investigated by theoretical calculation, and the phase diagram was validated by DSC and XRD experiments. The phase diagram is composed by three eutectic reactions and two intermediate compounds of Fez VO4 and FeVO4. The calculated results of FeO-V2O5 binary phase diagram are close to the experimental results from XRD and DSC.
