High-temperature thermal conductivity of ferroelectric and antiferroelectric perovskites. [EN]

Authors of the publication: - M Tachibana - C Bourges - T Mori

We report thermal conductivity (κ) above 300 K for perovskite ferroelectrics BaTiO3 (Tc ≈ 402 K) and PbTiO3 (763 K), as well as antiferroelectrics PbZrO3 (503 K) and PbHfO3 (476 and 433 K). BaTiO3 and PbTiO3 show similar κ in the paraelectric phase.

Thermal insulation materials are essential for restricting heat transfer and lowering overall energy usage. Hollow ceramicmicrospheres (HCM) have recently gained popularity as insulation due to their high thermal resistance and thermal integrity at elevated temperature at low cost [1].
