| 英文摘要 | (1-x)(Bi0.5Na0.5)TiO3-xBa(Ni0.5Nb0.5)O-3 (x = 0-0.04) lead-free ceramics (abbreviated as (1-x) BNT-xBNN) were synthesized by a conventional solid-state reaction method. The effect of BNN contents on phase structure, microstructure, ferroelectric, dielectric, pyroelectric properties and thermal stability of (1-x)BNT-xBNN ceramics were systematically investigated. The pyroelectric coefficient (p) at room temperature increased gradually from 3.01 x 10(-8) C cm(-2)K(-1) at x = 0 to 5.94 x 10(-8) C cm(-2) K-1 at x = 0.04. The dielectric loss (tan delta) and dielectric constant (epsilon(r)) decreased first with the small amount of BNN content, then increased slightly with further BNN addition, acquiring the minimum tan delta and epsilon(r) at x = 0.02. When x = 0.02, the optimal over-all properties were observed with pyroelectric figure of merit (FOMs) of F-v = 3.82 x 10(-2) m(2) C-1 and figure of merit of F-d = 2.74 x 10(-5) P a(-1/2). More importantly, the depolarization temperature (T-d) of 0.98BNT-0.02BNN ceramics is up to similar to 195 degrees C which is higher than most other reported BNT-based ferroelectric ceramics. In addition, it can be exposed to temperature up to similar to 145 degrees C with negligible deterioration of pyroelectric properties, showing excellent thermal stability. The overall properties reveal that 0.98BNT-0.02BNN ceramics is a promising pyroelectric material for infrared detectors. |
