Abstract: PZT ceramics, usually used pyroelectric materials exhibited a relatively highly Curie temperture(Tc) of 250-450℃ and permittivity constant of 500-1600. In this paper, the pyroelectric infrared detectors are applied two different types of pyroelectric materials, that is tetragonal crystal of ferroelectric PbTiO 3 and rhombohedral crystal of Pb(Zr,Ti)O 3 . PZT ceramics shows not only highly Curie temperture but also excellent pyro and piezoelectric properties at the Zr/Ti(=52/48) ratio. Therefor in this paper, the pyroelectric infrared detectors are applied PZT ceramics, and obtained sensitive sensing characteristics by expriment case studies.
