【 摘 要 】

Ferroelectric ceramic dielectrics have electrothermal effects, which usually show some changes in the thermodynamic quantities such as heat capacity and temperature under the action of electrostatic field. In the past few decades, it has only been found that there is a small electrothermal effect in polar ferroelectric ceramic dielectric materials. Recently, some ferroelectric materials have been found to have a large electrothermal effect, so the design of a refrigerator by using the electric method can be used as a research hotspot. In this work, we firstly introduced the electrothermal effects of polar ferroelectric ceramic dielectric materials, and then intensively discussed the refrigerating materials and their refrigeration capacities. Finally, it is hoped that it can be used as a reference for other refrigerating materials in the future.
