Non-isothermal kinetics of synthesizing vanadium nitride by one-step methodJiang Dong,Yue Yu,Zheng-Liang XueSchool of Materials and Metallurgy,Wuhan University of Science and Technology摘 要:Vanadium nitride was synthesized by one-step method using V2O5 and carbon black as raw materials in nitrogen atmosphere. The phases of different reaction products......
were analyzed in detail.(NH4)2SO4 and KHSO4 were used as fusing agents to transform compounds containing vanadium into soluble species. Mass ratio of (NH4)2SO4 to CS, mass ratio of KHSO4 to CS, and roasting temperature during the roasting process can significantly influence leaching rate of vanadium (LRV). With H2SO4 as leaching agent, 99.2%vanadium in CS can be leached out under the optimum......
