利用高温淬火方法得到钒渣渣系的高温物相,采用X-ray衍射分析方法确定钒渣的物相组成,分别研究了V2O3含量及n(FeO)(SiO2)对钒渣中V2O3溶解能力的影响.结果表明,钒铁尖晶石和Fe3O4为钒渣中存在的固定相;钒渣中V2O3含量不断增加,V2O3的溶解度随之增加,但n(FeO) ( SiO2 )＜1.5,V2O3增加到一定量时,溶解度无明显变化;n(FeO) ( SiO2)不断增大,V2O3在钒渣中的极限溶解度也随之增加.%The phase of the vanadium slag at high-temperature was obtained by high temperature hardening method. Then the composition of the slag phase was analyzed by X-ray diffraction. On this basis, the influence of V2O3 solving ability from V2O3 content and n(FeO)(SiO2) in vanadium slag can be derived. The results show that the vanadium and iron spinel, Fe3Q4 are stationary phases in vanadium slag. The solubility of V2O2 in vanadium slag increased when the content of V2O3 increasing. But when n(FeO)(SiO2)展开▼
