Measurements in the temperature range 1 to 55K are reported for K/sub x/WO/sub 3/, Rb/sub x/WO/sub 3/, Cs/sub x/WO/sub 3/, Tl/sub x/WO/sub 3/, WO/sub 3/ and Na/sub x/WO/sub 3/ and the excess heat capacity due to an Einstein mode is found in K/sub x/WO/sub 3/, CsWO/sub 3/ and Tl/sub x/WO/sub 3/. A value of x equals 0.33 is determined. The general results are discussed and related to the superconducting properties of the four hexagonal bronzes. 25 references.
