摘要
The 1 wt% Li-doped (Ba0.85Ca0.15)(Zr0.1Ti0.9)O-3 (BCZT-Li) ceramics were prepared by a citrate method. The effects of calcination temperature on the structure and pyroelectric properties of the BCZT-Li ceramics were investigated. The orthorhombic phase and tetragonal phase coexist in all the BCZT-Li ceramics calcined at different temperatures. All the BCZT-Li powders exhibit the type III adsorption-desorption curves. The increase of calcination temperature leads to the growth of the particle size of the BCZT-Li powders. However, the abnormal growth of grains appears when the calcination temperature exceeds 650 degrees C, leading to the deterioration of pyroelectric properties of the BCZT-Li ceramics. The BCZT-Li ceramics calcined at 650 degrees C exhibit the best pyroelectric properties, in which the pyroelectric parameters p, F-d, F-v, and F-i is 860 mu C.m(-2).K-1, 15.8 mu Pa-1/2 (100 Hz), 0.015m(2)/C (100 Hz), and 407.6pm/V, respectively. The excellent pyroelectric properties of the BCZT-Li ceramics calcined at 650 degrees C can be attributed to the polymorphic ferroelectric phase transition occurring around room temperature and the optimized calcination temperature. Such investigations reveal that the BCZT-Li ceramics are promising lead-free materials in the pyroelectric devices. (C) 2015 The Japan Society of Applied Physics
