Ba 0.6 Sr 0.3 Ca 0.1 TiO 3 ceramics were prepared by solid‐state reaction technique and the dielectric and pyroelectric properties of poled specimens were systemically investigated. The dielectric constant and dielectric loss at Curie temperature for the poled specimens were 11 273 and 0.0152, respectively. The pyroelectric coefficient maximum about 40 × 10 −8 C cm −2 K −1 was detected and the figure of merit ( F d ) maximum about 9.77 × 10 −5 Pa −1/2 was obtained when 800 V mm −1 bias field was applied on the poled specimens. Based on the dielectric and pyroelectric data, the behaviors of the intrinsic pyroelectric response and the field induced pyroelectric response under DC bias field were also discussed.
