The thermal conductivity of the charge density wave material K{sub 0.30}MoO{sub 3} was measured along the b axis between 40 and 300 K. Below the transition, the thermal conductivity is typical of a crystalline insulator in which Umklapp processes are the dominant mechanism for phonon scattering. In the vicinity of the transition, 150 K to 190 K, the thermal conductivity increases with increasing temperature as electrons excited across the charge density wave gap contribute to heat transport. The magnitude and the temperature dependence of the additional conductivity is well-described by the Wiedemann-Franz law.
