Pb(Zr0.9Ti0.1)O3 pyroelectric thick films adding various amounts of the sintering aids Bi2O3–Li2CO3 have been deposited on the substrates Al2O3 by the screen-printing process, and the dependence of microstructure, dielectric and pyroelectric properties on the content of sintering aids has been studied. When the amount of Bi2O3–Li2CO3 increases from 0 wt% to 5.4 wt%, the sintering temperature of the thick films decreases from 1100 °C to 900 °C, and the grain size and the lattice constant decrease either, but the density and the dielectric constant increase. The Pb(Zr0.9Ti0.1)O3 thick film with 5.4 wt% of Bi2O3–Li2CO3 sintered at 900 °C has the maximum pyroelectric coefficient 10.51×10−8 C/cm−2 K−1 and the highest figure-of-merit 10.58×10−5 Pa−0.5.
