首先,对钠化氧化提钒的热力学进行了计算和分析,然后采用热重天平、差热分析、光学显微镜、X射线衍射、扫描电镜等手段,对钒钛磁铁矿球团的氧化过程、钒转化反应和物相的变化进行了实验研究。通过研究,找到了球团焙烧时铁氧化、钒转化和硫酸钠反应三者之间的关系;同时指出了硫酸钠和五氧化二钒相互作用时,V_2O_5不是起催化作用,而是直
Firstly, the thermodynamics of vanadium titanomagnetite was calculated and analyzed. Then, the oxidation process of vanadium titanomagnetite pellets was studied by means of thermogravimetry, differential thermal analysis, optical microscope, X-ray diffraction and scanning electron microscope. Vanadium conversion reaction and the phase changes of the experimental study. Through the research, the relationship between iron oxide, vanadium conversion and sodium sulfate reaction was found when the pellets were roasted. At the same time, it was pointed out that when the interaction between sodium sulfate and vanadium pentoxide, V 2 O 5 did not play a catalytic role,
