Abstract

Multicomponent single-phase rare earth zirconates LaGdZr₂O₇, (LaSmGd)_2/3Zr₂O₇, (LaSmGdY)_1/2Zr₂O₇, (LaNdSmGdY)_2/5Zr₂O₇ of the pyrochlore structure were synthesized. The isobaric heat capacity at 300–1800 K and thermal diffusivity were measured. The thermal conductivity of non-porous samples in the range of 300–1300 K was calculated.
