[1A04] The bredig transition effect on the thermal conductivity of CaF2

*Taku Matsumoto1, Ryota Tsuchimochi1, Shun Hirooka1, Masato Kato1, Josha Taylor White2, Kenneth James McClellan2 (1. Japan Atomic Energy Agency, 2. Los Alamos National Laboratory)

Keywords:Bredig transition, Thermal conductivity

The thermal diffusivity, thermal expansion and heat capacity of CaF2 was measured with LFA, DIL and DSC up to 1250℃, then the thermal conductivity was evaluated. We evaluated how the Bredig transition which is one of the unique feature of fluorite structure affect on the thermal conductivity.
