Electrolytic characterization showed that it was quite conductive, with a room-temperature conductivity of 0.00023S/cm, and a value of 0.0137S/cm at 210C. The conductivity involved mainly anionic-type defects; with ionic transport numbers greater than 0.98 for temperatures ranging from 22 to 215C. The activation energy for Br vacancy motion was 0.27eV. The use of X-ray, differential thermal analysis and thermogravimetric techniques also showed that the material had a cubic lattice with a lattice parameter of 0.908nm. It melted at 271C and was thermally stable at temperatures of up to 450C.
