2016年12月26日,钒钛国重点实验室主任胡鸿飞主持召开东北大学承担的“五氧化二钒—氧化钙(氧化钠)—三氧化二铬伪三元相图的建立研究”开放课题验收审查会。会上,东北大学材料冶金学院王明华副教授报告了通过对焙烧过程中钒渣中各主要组分的价态、物相变化过程及机理研究,提出了钒渣焙烧主要组分混合的相图建立过程及结果讨论。与会人员就所关注的试验方法、平衡温度,平衡时间、平衡组织、熔点及所建立的伪三元相图生产工艺指导性等作了交流探讨。评审认为:该项目采用XRD半定量、配合SEM检测、EDX分析、TG分析、DTA分析等方法,进行了不同组分、不同温
On December 26, 2016, Hu Hongfei, director of the key laboratory of Vanadium and Titanium, presided over the “Research on the Establishment of Pseudo ternary Phase Diagram of Vanadium Pentoxide-Calcium Oxide (Sodium Oxide) -Chromium Oxide” undertaken by Northeastern University Questions acceptance review. At the meeting, associate professor Wang Minghua of Northeastern University School of Material and Metallurgy reported on the valence of the main components of the vanadium slag roasting process and mechanism of the phase change, the main component of vanadium slag roasting phase diagram of the establishment of the process of mixing Discuss the results. Participants discussed the test methods of interest, the equilibrium temperature, the equilibrium time, the equilibrium organization, the melting point and the production process guidance of the established pseudo-ternary phase diagram. The review concluded that: The project uses semi-quantitative XRD, with the SEM test, EDX analysis, TG analysis, DTA analysis methods, different components, different temperature
