Abstract :
According to the requirement of pyroelectric ceramics used for commercial IR detector without FET gate resistor PbZrO3-PbMnSbO3-PbTiO3 pyroelectric ceramics with high figure of merit and low resistivity were studied. The resistivity ρ of above system can be adjusted in the range of 0.8-5×1011 Ωcm by further Mn doping. The signal to noise ratio of the detector without gate resistor made by this ceramics can reach the same level of the detector with FET gate resistor. The large size ceramic blocks with good mechanical processing property can be manufactured by pressureless sintering
