Abstract
High resolution specific heat measurements have been performed on K0.3 MoO3 and K0.15Tl0.15MoO3 in the temperature region between 90 and 220K . Specific heat anomalies are observed at 178K and 164.8K for K0.3MoO3 and K0.15Tl0.15MoO3 respectively. The specific heat jump, entropy and enthalpy changes associated with the CDW phase transition are estimat ed The results suggest that perfect order of K polyhedral chains is im portant for the phase transition of K blue bronze.
