Pyroelectric Ceramic Materials For Uncooled I.R. Detectors

Pyroelectric ceramics offer a number of advantages over single crystal materials for use in infra-red detectors. This paper discusses these advantages and describes the development of hot-pressed ceramic compositions within the PbZr03-Pb2FeNb06-PbTiO3 system and the control of their relevant electrical properties by doping with uranium oxide.
