Heat Capacity of Rubidium Tungsten Bronze
Rubidium tungsten bronze (Rb x WO3) is a nonstoichiometric metallic compound whose variation in x value allows the electron concentration to be changed without altering the crystal structure. Magneli,1 who determined the crystal structure, found that the hexagonal lattice has channels along the c axis formed from WO6 octahedra joined at their corners. The rubidium ions lie in these channels. When all the channel sites are occupied x = 0.33, so this x value corresponds to the upper limit for the formation of hexagonal Rb x WO3.
