摘要：

The pyroelectric and dielectric bolometer properties of Sr modified BaTiO3 ceramics were investigated for thermal IR detector applications. The (Ba-1 x,Sr-x)TiO3 solid solution ceramics have been prepared by adding 10-40 at % SrTiO3 to BaTiO3 and with different sintering conditions and under dc fields. The relationships of processing parameters, microstructures, dielectric/pyroelectric properties and dc fields are discussed. And the "figures of merit" are compared between pyroelectric-type and dielectric bolometer-type IR sensors based on the experimental results. (C) 1999 Kluwer Academic Publishers.
