ABSTRACTAbove To = 196 K, white phosphorus, a solid composed of P4 molecules, exhibits a plastic crystal phase. Below this temperature, the structure is triclinic and orientationally ordered, with six molecules in a unit cell. Using inelastic neutron scattering on a polycrystalline sample, observations were made of the rapid reorientational motions above To, and the librational modes below To. In addition, neutron powder diffraction was used to investigate the crystal structures above and below To.

Diffusion Of Hydrogen

AbstractCu-Li-Mg-(H,D) was studied as an example of destabilizer of the Ti-(H,D) system. A Cu-Li-Mg alloy was prepared resulting in the formation of a system with 60.5 at% of CuLi0.08Mg1.92, 23.9 at% of CuMg2 and 15.6 at% of Cu2Mg. Titanium was added to a fraction of this mixture so that 68.2 at% (47.3 wt%) of the final mixture was Ti. The mixture was ground and kept at 200 °C/473 K for 7h under H2 or 9h under D2 at P = 34 bar. Under those conditions, neutron powder diffraction shows the formation of TiD2, as well as of the deuteride of CuLi0.08Mg1.92. Similarly inelastic neutron scattering shows that at 10 K TiH2 is present in the sample, together with the hydride of CuLi0.08Mg1.92. Interestingly, at 10 K TiH2 is very clearly detected and at 300 K TiH2 is still clearly present as indicated by the neutron vibrational spectrum, but CuLi0.08Mg1.92-H is not detected anymore. These results indicate that Ti(H,D)2 is possibly formed by diffusion of hydrogen from the Cu-Li-Mg-(H,D) alloys. This is an intriguing result since TiH2 is normally synthesized from the metal at T > 400°C/673 K (and most commonly at T ˜ 700 °C/973 K). In the presence of CuLi0.08Mg1.92, TiH2 forms at a temperature that is 300 – 400 K lower than that needed to synthesize it just from the elements.
