Summary on Grant Application Form |

This proposal seeks funding to support a PDRA to prepare, characterise and explore the exploitation of materials that both contract in volume when heated and display unusual oxygen mobility.Attention will focus on the zirconium tungstate/molybdate family of compounds ZrW2 - xMox08 and related materials AM207 (where A=Zr, Hf, Sn, M=P, V, As etc). Low temperature synthetic routes will be employed to prepare new materials within this general family. Structural properties and their relation to negative thermal will be studied using a combination of powder and single crystal X-ray diffraction methods, neutron scattering experiments and solid state NMR. Properties to be explored will include low temperature (200 K) oxygen migration in ZrW2 - xMox08 and related materials; the possibility of aliovalent doping in these phases; unusual phase transitions in AM207 materials; and thermal expansion properties of all these systems.I believe that the combination of the synthetic expertise and state of the art variable temperature diffraction equipment available in Durham, together with access to the UK's world-beating neutron facilities, will give us a unique opportunity to run a globally competitive research programme in this technologically important area.
