Thermal stability and curing kinetics of polycarbosilane fibers ZHENG Chun-man (郑春满), LI Xiao-dong (李效东), WANG Hao (王 浩), ZHU Bin(朱 冰) (State Key Laboratory of New Ceramic Fibers and composites...; Abstract: Thermal stability and curing kinetics of polycarbosilane (PCS) fibers were studied by thermogravimetry (TG), Fourier transform infrared spectroscopy(FT-IR). Curing......
Reduction Kinetics of Nickel Sulphide刘中华,刘纯鹏摘 要:<正> Reduction kinetics of Ni3S2 was experimen-tally studied by following the time required forcompletion of the hydrogen reduction reaction inthe presence of calcium oxide.A simple empiricalintegration equation,derived for describing the ef-fect of CaO/S molar ratio,temperature,hydrogenconcentration......

State Key Laboratory of Advanced Metallurgy,University of Science and Technology Beijing2. School of Metallurgical and Ecological Engineering,University of Science and Technology Beijing摘 要:Reduction of titanomagnetite(TTM......
are 55.43 kJ/mol and 174.54 kJ/mol for the initial and the final stages, respectively. Key words: Fe2O3-Cr2O3-NiO system; isothermal reduction; reduction degree; kinetics; reaction mechanism 1... rarely occurs under experimental conditions. Therefore, solid carbon or carbon dissolved in the (Fe, Ni) alloy is the reductant at the final stage for the reduction of Cr2O3. 3.4 Reaction kinetics......

products are mostly reduced iron, rutile, reduced rutiles, Ti3O5 and pseudobrookite solid solution. The reduction kinetics was also discussed. The results show that the reduction temperature is a key factor to control reaction rate. Key words: Bama ilmenite; reduction; thermogravimetry; impurity; kinetics  ......
Kinetics of magnesium preparation by vacuum-assisted carbothermic reduction methodWei-dong Xie1,2,Jie Chen1,Hao Wang3,Xi Zhang1,Xiao-dong Peng1,2,Yan Yang11. School of Materials Science... of reactions were carried out under various vacuums, reaction temperatures, and time. Reaction kinetics of carbothermic reduction process was investigated. The results reveal that the morphologies......
