The electricaloric refrigeration is based on the electricaloric effect due to its high energy conversion efficiency, environment friendly, small size and easy integration as a novel efficient refrigeration technology, which has become one of the emerging research hotspots in the field of ferroelectric. The solid solutions of 0.77NaNbO3-0.23BaTiO3+wMn (w=0, 0.2%, 0.4% and 0.6%, in mass fraction) electrocaloric ceramics were prepared by a conventional solid-state reaction method. The phase composition and microstructure of 0.77NaNbO3-0.23BaTiO3 ceramics with different Mn doping contents were characterized by X-ray diffraction and scanning electron microscopy. Meanwhile, the dielectric-temperature spectra, polarization electric field hysteresis loops and electrocaloric effect of the samples with different Mn doping contents were determined. The results indicate that Mn doped ceramics can promote the grain compaction, improve the dielectric constant and saturation polarization strength, reduce the dielectric loss, and enhance the electrocaloric effect. For the ceramic with Mn doping content w of 0.4%, ΔT=0.39 K, and ΔS=0.71 J·kg-1·K-1, the electrocaloric strength of ΔT/ΔE enhances from 0.05×10-6 K·m·V-1 to 0.13×10-6 K·m·V-1, and ΔS/ΔE enhances from 0.08×10-6 K m·V-1 to 0.24×10-6 J·m·kg-1·K-1·V-1 under 30 kV·cm-1 at room temperature. It is indicated that 0.77NaNbO3-0.23BaTiO3+0.4%Mn ceramic could be used as an promising electrocaloric refrigeration material.

电卡制冷基于电卡效应，由于其能量转换效率高、环境友好、体积小易于集成等优势，被认为是新一代高效制冷技术，已成为铁电领域新兴研究热点之一。本工作采用传统固相反应法制备了0.77NaNbO3-0.23BaTiO3+wMn（w=0、0.2%、0.4%、0.6%，质量分数）电卡陶瓷样品，研究了不同Mn掺杂量对0.77NaNbO3-0.23BaTiO3陶瓷的物相组成和微观形貌，测量了不同Mn掺杂量样品的介温谱、电滞回线和电卡效应。结果表明：适量Mn掺杂陶瓷样品可以促进晶粒的致密化、提高介电常数和饱和极化强度、并显著提升其电卡效应，当掺杂量w=0.4%时，室温下样品的温变值ΔT由0.09 K提升到0.39 K，熵变值ΔS由0.17 J·kg-1·K-1提升到0.71 J·kg-1·K-1，电卡强度ΔT/ΔE=0.13×10-6 K·m·V-1，ΔS/ΔE=0.24×10-6 J·m·kg-1·K-1·V-1（E=30 kV·cm-1），由此可知，0.77NaNbO3-0.23BaTiO3+0.4%Mn陶瓷是一种具有应用前景的电卡制冷材料。

摘要
收起

电卡制冷基于电卡效应，由于其能量转换效率高、环境友好、体积小易于集成等优势，被认为是新一代高效制冷技术，已成为铁电领域新兴研究热点之一。本工作采用传统固相反应法制备了0.77NaNbO3-0.23BaTiO3+wMn（w=0、0.2%、0.4%、0.6%，质量分数）电卡陶瓷样品，研究了不同Mn掺杂量对0.77NaNbO3-0.23BaTiO3陶瓷的物相组成和微观形貌，测量了不同Mn掺杂量样品的介温谱、电滞回线和电卡效应。结果表明：适量Mn掺杂陶瓷样品可以促进晶粒的致密化、提高介电常数和饱和极化强度、并显著提升其电卡效应，当掺杂量w=0.4%时，室温下样品的温变值ΔT由0.09 K提升到0.39 K，熵变值ΔS由0.17 J·kg-1·K-1提升到0.71 J·kg-1·K-1，电卡强度ΔT/ΔE=0.13×10-6 K·m·V-1，ΔS/ΔE=0.24×10-6 J·m·kg-1·K-1·V-1（E=30 kV·cm-1），由此可知，0.77NaNbO3-0.23BaTiO3+0.4%Mn陶瓷是一种具有应用前景的电卡制冷材料。

The electricaloric refrigeration is based on the electricaloric effect due to its high energy conversion efficiency, environment friendly, small size and easy integration as a novel efficient refrigeration technology, which has become one of the emerging research hotspots in the field of ferroelectric. The solid solutions of 0.77NaNbO3-0.23BaTiO3+wMn (w=0, 0.2%, 0.4% and 0.6%, in mass fraction) electrocaloric ceramics were prepared by a conventional solid-state reaction method. The phase composition and microstructure of 0.77NaNbO3-0.23BaTiO3 ceramics with different Mn doping contents were characterized by X-ray diffraction and scanning electron microscopy. Meanwhile, the dielectric-temperature spectra, polarization electric field hysteresis loops and electrocaloric effect of the samples with different Mn doping contents were determined. The results indicate that Mn doped ceramics can promote the grain compaction, improve the dielectric constant and saturation polarization strength, reduce the dielectric loss, and enhance the electrocaloric effect. For the ceramic with Mn doping content w of 0.4%, ΔT=0.39 K, and ΔS=0.71 J·kg-1·K-1, the electrocaloric strength of ΔT/ΔE enhances from 0.05×10-6 K·m·V-1 to 0.13×10-6 K·m·V-1, and ΔS/ΔE enhances from 0.08×10-6 K m·V-1 to 0.24×10-6 J·m·kg-1·K-1·V-1 under 30 kV·cm-1 at room temperature. It is indicated that 0.77NaNbO3-0.23BaTiO3+0.4%Mn ceramic could be used as an promising electrocaloric refrigeration material.
