    The structural and hydrogen absorption/desorption properties of the new AB3- type compound CeTi2Ni4.5Al0.2Mn0.3Cr4 used as material for negative electrode in Ni – MH batteries were investigated. The elaboration of the CeTi2Ni4.5Al0.2Mn0.3Cr4 was carried by mechanical alloying process starting from CeNi4.5Al0.2Mn0.3 and TiCr2 compounds. The abundance of the CeTi2Ni4.5Al0.2Mn0.3Cr4 phase increases with

    indicates the formation of a solid solution formation by the reaction of TiO 2 with Cr 2 O 3 . As the temperature increased to about 950 °C the Ca started to melt (at approximately 847 °C) resulting to an exothermic peak due to the reaction of Ca with Cr 2 O 3 forming Cr metal. The formation of CaTiO 3 formed by the reaction of CaO with TiO 2 decreased the amount of TiO 2 in the mixture of starting materials
    摘要 利用TiO 2 -Cr 2 O 3 氧化物的钙热共还原直接合成TiCr 2 金属间化合物粉末的新工艺路线。差热分析 (DTA) 和 X 射线衍射 (XRD) 用于确定各种反应。根据 DTA 结果,将混合物加热至约 675 °C 导致吸热峰。该吸热峰表明通过TiO 2 与Cr 2 O 3 的反应形成了固溶体。随着温度升高至约 950 °C,Ca 开始熔化(在约 847 °C 时),由于 Ca 与 Cr 2 O 3 反应形成 Cr 金属而导致放热峰。CaO与TiO 2 反应形成的CaTiO 3 的形成降低了起始材料混合物中TiO 2 的量。当混合物加热到 1058°C 时,如形成Ti的放热反应所示,Ca与TiO 2 反应形成Ti。最后,当1200℃保温时间和Ca含量增加时,形成TiCr 2 金属间化合物,同时CaTiO 3 化合物逐渐分解为CaO和Ti,样品中氧含量降低。得到的金属间化合物粉末经活化后显示出储氢能力。
  • The investigation of the Zr1−yTiy(Cr1−xNix)2–H2 system 0.0≤y≤1.0 and 0.0≤x≤1.0 Phase composition analysis and thermodynamic properties
    作者:M Bououdina、H Enoki、E Akiba

    The Zr1-yTiy(Cr1-xNix)(2) compounds were synthesized and characterized by means of X-ray powder diffraction. From the Rietveld analysis carried out on the alloys, we determined the phase abundancy and refined the crystal structure. The system crystallized with hexagonal C14-type structure for nickel content less than x = 1.0 with some amount of additional phases (ZrNi, Zr9Ni11, Zr7Ni10, TiNi) and pure metals (Ni and Cr). For higher nickel concentrations, the system crystallized in the cubic C15-type structure. The amount of additional phases increased with increasing nickel and titanium content. The Pressure-Composition-Temperature measurements using a volumetric method were carried out at 313 K on some selected alloys. The single phase systems were found to absorb a large amount of hydrogen (H/M less than or equal to 1.8 wt.%) but had very poor kinetics. The multiphase systems were found to behave as a single phase (presence of single plateau), have a relatively good hydrogen capacity (H/M less than or equal to 1.4 wt.%) and exhibit faster kinetics. A Linear correlation between the heat of formation of the Zr1-yTiy(Cr1-xNix)(2) hydrides estimated from the band structure model and the unit cell volume of the alloys determined from the X-ray Rietveld analysis was obtained. It shows a decrease of hydride stability with increasing unit cell volume. (C) 1998 Published by Elsevier Science S.A. All rights reserved.
