Abstract

The low‐temperature sintering and electric properties of Pb 0.99 ( Zr 0.95 Ti 0.05 ) 0.98 Nb 0.02 O 3 ( PZTN 95/5) ferroelectric ceramics with CuO addition was investigated. The CuO addition significantly promoted the densification and reduced the sintering temperature of PZTN 95/5 ceramics by more than 200°C. The 0.2 wt% CuO ‐added sample sintered at 1150°C exhibited the optimum relative density of 96.7% and excellent electric properties with values of P r = 37.80 μC/cm 2 , T C = 223°C, ε r = 329, and tan δ = 0.016, which were superior to that of PZTN 95/5 ceramics sintered at 1350°C.
