A novel magnesium–vanadium hydride synthesized by a gigapascal-high-pressure technique

A new ternary magnesium–titanium hydride Mg7TiH with hydrogen desorption properties better than both binary magnesium and titanium hydrides

“…225)). This new system shows a 160 K lower desorption temperature compared to magnesium hydride [6]. No binary Mg-V alloys exist and the new Mg 6 V metal atom framework is held together by hydrogen.…”

“…3 is based on full occupancy of the possible atomic sites. Also the Mg 6 V hydride has Ca 7 Ge type structure, but contains vacancies [6]. The refinement of the X-ray diffraction pattern is shown in Table 2, observed and calculated intensities from the Rietveld refinement are shown in Fig.…”

MgH 2 thin films deposited by one-step reactive plasma sputtering

“…On the other hand, in some conditions, the non-equilibrium synthesis process allows the growth of films mainly composed of the metastable medium pressure gMgH 2 phase. This result shows that this synthesis method is a promising route for the growth of metastable phases such as ternary magnesium -transition metal elements hydrides synthesized under extreme conditions [34]. Most investigations on hydride thin films are almost exclusively related to a posteriori hydrogenated metallic films; in particular recent works are dedicated to the destabilization of thin films of Mg-based hydrides [9,31,35e38].…”

A thermodynamic study of the hydrogenation of the pseudo-binary Mg6Pd0.5Ni0.5 intermetallic compound

“…Some examples of members of this family are, Mg 29 Ir 4 [12], Mg 6 Pd [13], Mg 6 Pt [14], Mg 44 Rh 7 [15], Mg 44 Ru 7 [16]. In addition, other members of the Mg y X family hydrides like Mg 6 Ni [17], Mg 6 V [18] or Mg 7 Ti [19] have been prepared at H 2 pressure in the GPa range being most of them only stable at such high pressure conditions.…”
