Metal Fe,Ni and Fe-Ni Fine Fibers Derived from the Organic Gel-Thermal Reduction Process沈湘黔摘 要:<正>The organic gel-thermal reduction process... with diameters of arotuld 1μm and lengths of as long as 2 m for Ni fibers,0.5 m for iron fibers,1 m for Fe-Ni fibers.The structure,thermal decomposition process and morphologies of the gel precursors......
of numerical simulation was applied to investigate gas preheating and start-up process in a drained aluminum reduction cell. The transient temperature and velocity fields of a 156 kA drained aluminum reduction cell were numerically calculated. The results show that the method of gas preheating and bake-out can basically meet the technical requirements of the start-up process for the drained cell......

Towards the diffusion source cost reduction for NdFeB grain boundary diffusion processH.X.Zeng,Z.W.Liu,J.S.Zhang,X.F.Liao,H.Y.YuSchool of Materials Science and Engineering, South China University of Technology摘 要:Aiming at improving the performance/cost ratio in grain boundary diffusion process(GBDP),the critical RE containing Pr-Al-Cu alloy,less......
numerous attempts to produce aluminum from chemical reduction to electrolytic reduction[1-4]. The production of aluminum was a chemical reduction process in the early periods, which was given up... consumption was thus significantly lower than that by Hall-Héroult process. Replacement of the electrochemical process by carbothermic reduction of Al2O3 would decrease the total greenhouse gas......
