Barium-titanate-based colossal-electrocaloric-effect chip-type laminate ceramic electrocaloric refrigeration device
The invention provides a barium-titanate-based colossal-electrocaloric-effect chip-type laminate ceramic electrocaloric refrigeration device. The chip-type laminate ceramic employs perovskite ABO3 structural barium titanate as a matrix for A-position doping or B-position doping or A position and B position simultaneous doping, so that a combined phase is formed. The device possesses the following advantages that through doping, the sintering condition of the chip-type laminate ceramic is improved, the sintering temperature is reduced and further energy consumption of the technology is reduced; the material mechanical properties (pressure resistance, stretching performance, shearing performance and toughness) are improved, and the material can satisfy demands of more usage environments; and the effective working temperature interval of the material is expanded.
