On the increase in thermal diffusivity caused by the perovskite to post-perovskite phase transition and its implications for mantle dynamics

Hunt, Simon A.; Davies, Rhodri; Walker, Andrew; McCormack, Richard J.; Wills, Andrew S.; Dobson, David P.; Li, Li

Description

The thermal diffusivity (κ) of perovskite and post-perovskite CaIrO 3 has been measured, at elevated pressure and temperatures up to 600°C, using the X-radiographic Ångström method. At high temperatures we find that the thermal diffusivity of post-per
