    Hydrogen storage in magnesium–metal mixtures: Reversibility, kinetic aspects and phase analysis
    摘要:
    The sorption capacity and kinetics of mechanically activated binary mixtures of Mg with nine different metals (Al, Cu, Fe, Mn, Mo, Sn, Ti, Zn, Zr) have been studied to determine whether these metals act as catalyzing/destabilizing agents in formation/decomposition of Mg hydrides. Identification of crystalline phases before and after the absorption/desorption processes assists our understanding of the different behaviors displayed by the studied compounds. Cu, Al and Zn take active part in Mg hydrogenation/dehydrogenation, but only the addition of Cu is actually effective in MgH2 destabilization, leading to a substantial decrease of the desorption temperature of this phase (down to 270 degrees C), and to an improved desorption kinetics. With the other metals, the hydrogen release usually occurs at a significant rate only above 320 degrees C and the kinetics of the absorption/desorption processes are slower than in the Mg/MgH2 System(C) 2007 Elsevier B.V.

    Microstructure and superconductivity of MgB2 synthesized by using Mg-based compound powders
    摘要:
    MgB2 can be synthesized through a new route using Mg2Cu instead of pure Mg. When the temperature is elevated to around the melting point of Mg2Cu (568 degreesC), the T-c for Mg2Cu/B Fe-sheathed wires increases rapidly to about 37.5 K. Mg2Cu with its low melting point promotes the diffusion reaction to form a high T-c MgB2 at low temperatures. A lot of second phases forms with small amounts of MgB2 in the core of the wires. However, the transport J(c) value, which is greater than 10(5) A/cm(2) at 4.2 K in ambient fields, is rather high. Since the J(c) value is estimated from a net-cross-sectional area of MgB2 it is expectedly high. Moreover, Mg-2 Cu/B/metal-substrate layered composites were also prepared in this study. After a heat treatment at 600 degreesC for 10 h in a vacuum, a 50 mum thick MgB2 diffusion layer forms with a high-density microstructure. Cu is released from Mg2Cu, and collects on the surface of the diffusion layer. This behavior of Cu is similar to that of the bronzed process used for Nb-3 Sn practical conductors.

    Mg10YNi + 4Cu (in mole ratio) powders at 4 MPa H2 followed by sintering at 400 °C for 20 h under an argon pressure of 0.6 MPa. It is found that the kinetic properties of both the disproportionation reaction of Mg2Cu and its reverse reaction can be enhanced in comparison with those of undoped Mg2Cu. The improvement of hydrogen absorption/desorption kinetics is attributed to the nanocrystalline Mg2Ni and YH2/YH3

The pressure composition (PC) isotherm for Mg83.3Cu7.2Y9.5 at 400 °C combined with XRD analysis allows one to understand the three-step hydrogenation pathway, detailed in this paper. At this hydrogenation temperature, the fully hydrogenated compound contains magnesium hydride exclusively crystallized

By comparison with our measured XRD pattern for MgCu2 samples, the reflection line located at 2θ ≈ 36° for Cu-sheathed MgB2 wires has been unambiguously identified as the (2 2 0) line of the MgCu2 impurity phase. This line was previously unidentifiable due to its absence in current PDF database. The calculated XRD pattern for MgCu2 was found to match well with the measured
