Lead-free 0.94Na 0.5 Bi 0.5 TiO 3 -0.06Ba 1?x TiO 3 (NBT-0.06B 1?x T) ceramics (0.0 B x B 0.03) were synthesized by a conventional solid-state reaction process. X-ray diffraction shows that the compositions are at the morphotropic phase boundary where rhombohedral and tetragonal phase coexist. Grain size slightly changes with the increase of Ba 2? content and reaches the minimum at x = 0.02. The depolarization temperature (T d ) decreases with the extra Ba 2? content but the lowest T d was obtained at x = 0.01-0.02. The pyroelectric coefficient (p) was measured as a function of Ba 2? content, and increased from 2.90 9 10 -4 to 3.54 9 10 -4 C m -2°C-1 , and from 55.3 9 10 -4 to 740.7 9 10 -4 C m -2°C-1 for x = 0.00 and 0.02 at RT, and depolarization temperature (T d ) respectively. The pyroelectric coefficient (p) shows a large increase with rising the temperature and reaches the maximum value at the depolarization temperature (T d ). The figures of merits of F i , F v and F D have all been improved with the addition of extra barium. These improved pyroelectric properties indicate that NBT-0.06B 1?x T is a promising material for pyroelectric applications or a wide range of temperature.

Nonstoichiometry lead-free 0.94Na x Bi y TiO 3 -0.06Ba z TiO 3 (N x B y T-0.06B z T) (from x = y = 0.5, z = 1.00 to x = 0.5, y = 0.534, z = 1.02) ceramic compositions were prepared by a conventional solid-state route. XRD shows that the compositions are at a morphotropic phase boundary where rhombohedral and tetragonal phases coexist. The depolarization temperature (T d ) can be lowered by modifying x, y and z. The pyroelectric coefficient (p) of nonstoichiometry N x B y T-0.06B z T compositions is greatly increased, compared with stoichiometry NBT-0.06BT composition, from 3.15 9 10 -4 C m -2°C-1 at room temperature (RT) and 23.9 9 10 -4 C m -10 m v -1 , 0.39 9 10 -10 m 2 C -1 and 138.7 9 10 -6 Pa -1/2 , respectively, at T d . The same composition also presents F C values which are *2.58 and *2.86 (910 -9 C cm -2°C-1 ) at RT at 100 and 1000 (Hz). N 0.5 B 0.534 T-0.06BT and N 0.5 B 0.534 T-0.06B 1.02 T compositions show a large p values at a wide temperature range. The enhanced pyroelectric properties make nonstoichiometry N 0.52 B 0.52 T-0.06BT composition a promising candidate for pyroelectric and other applications at wide temperatures range.
