pure oxygen at 800 ℃ for Fe-20Cr, Fe-30Cr and Fe-40Cr alloys with a high Cr content were investigated. The results show that the three alloys exhibit irregular oxidation kinetics under the cyclic... content at 800 ℃ XU Xun-hu1, ZHANG Tao2, WANG Ling1, ZHANG Hong-hua1, MEN Dan-dan1, XIANG Jun-huai1, AN Jiang-shan1 (1.

Synthesis gas production using oxygen storage materials as oxygen carrier over circulating fluidized bed LI Ranjia1,YU Changchun1,DAI Xiaoping2,HAO Zhengping2,WU Qiong1 (1.The Key Laboratory... gas production over Circulating Fluidized Bed (CFB) using oxygen storage materials as oxygen carrier was reported. First, oxygen in the air was chemically fixed and converted to lattice oxygen......
of the magnets have been studied. The results indicate that oxygen consumes the effective Sm content of the magnets and forms Sm2O3–the non-magnetism phase, which result in the dete- rioration...Effects of oxygen and carbon on the magnetic properties and microstructure of Sm2Co17 permanent magnetsTIAN Jianjun, ZHANG Shengen, and QU Xuanhui School of Materials Science and Engineering......
oxidation took place after the exhaustion of surface oxygen for the complete oxidation. After the 10th recycle, CO2 content was much lower than that of fresh one at the initial stage. Figure 1(b) shows... was lowered, and CO turned to be the main product. For the fresh sample, the amount of surface lattice oxygen was larger than those of subsequent cycles (Fig. 4(a) and Table 2). Therefore, CO2 content......
Preparation and analysis of zirconia oxygen sensors LUO Zhi-an(罗志安), XIAO Jian-zhong(肖建中), XIA Feng(夏 风) State Key Laboratory of Plastic Forming Simulation and Die and Mould Technology, Huazhong University of Science and Technology, Wuhan 430074, China Received 12 April 2006; accepted 25 April 2006 Abstract: Thimble zirconia oxygen sensors were prepared with yttria stabilized zirconia(YSZ......
exposed in air at 850 °C to evaluate the effect of α phase content on formation and evolution of ORL, and the stability and diffusion of oxygen in α- and β-Ti were investigated by first principles... α titanium alloy TA15 is more easily, and more α phase content in titanium alloy is beneficial for oxygen diffusion and formation of ORL. Due to the small ORL thickness (maximum is only ~60 μm......
