We request 3 days on GEM to perform in-situ neutron diffraction and electrical conductivity studies of LiBD4 (crystalline and after quenching from 500K) and 0.33LiI.LiBD4 as a function of temperature. The aim is to study the correlation between the mobility of the lithium ions in the higher temperature structures, and show the possibility of forming ion channels through the change in the structure at high temperature. Electrical conductivity measurements of the quenched LiBD4 will assess the ion mobility in a mixed amorphous crystalline phase while neutron data will identify the ratio of the crystalline and amorphous phases and the identity of the crystalline phase. Preliminary studies suggest that LiBD4 adopts the high temperature phase in the mixture 0.33LiI.LiBD4. This will be conclusively determined by neutron diffraction data and the electrical conductvity of the material assessed.
