oxygen permeation fluxes and the excellent structural stability under CO2 atmosphere, the CGOeP BC0.5F1.5O membrane is a great potential candidate material for separating oxygen from air in the oxy......
Viscous properties of new mould flux based on aluminate system with CeO2 for continuous casting of RE alloyed heat resistant steel亓捷1,刘承军1,李春龙2,姜茂发11. Key Laboratory for Ecological Metallurgy of Multimetallic Ores (Ministry of Education), Northeastern University2. Baotou Iron and Steel (Group) Co., Ltd.摘 要:The conventional mould fluxes can......
the effects of the ratios of Al2 O3 to AI,fluxes, and coprecipitated materials as raw materials on the luminescence properties of the synthesized YAG:Ce phosphors. When the amount of Al2 O3 x is varied......
fluxes can enhance the photoluminescence intensity of phosphor particles, that can be attributed both to the improvement of crystallization processes of YAG and to the stabilization of trivalence......
by thermogravimetry with different heating rates and gas fluxes. Experimental data treated according integral method and the kinetics parameter E was obtained with different gas flux. The results show... different gas fluxes 3 结论 (1) 铁精粉的氧化过程分为3个温度.氧化的主要阶段发生在400~600 ℃. (2) 整个氧化过程的表观活化能随温度的升高而降低,其反应的速度控制步骤变化过程为外扩散?内扩散?外扩散. (3) 在8 ℃/min的升温速率下,铁精粉氧化过程的最佳气体流量为45 mL/min.升温速率和反应气流量能够改变氧化产物的微观结构. 参考文......
