Effects of NiCuZn ferrite compositions on the properties of PZT/NiCuZn composite materials

Firstly,PZT [Pb0.95Sr0.05(Zr0.52Ti0.48)O3] nanopowder was prepared by sol-gel method. Then PZT/NiCuZn composite materials were prepared by a solid-state reaction method,which PZT and NiCuZn mass ratios were 1:9 and 3:7,respectively. Effects of Ni0.26-xCu0.19+xZn0.55Fe2O4 ferrite compositions on the microstructures and electromagnetic properties of low temperature sintering composite materials were investigated. The results show that the composite materials can be sintered at 900 ℃. When x = 0.02,and for the composite materials of 1:9 mass ratio,initial permeability is 92,Q-value is 39,e' is 19,while the composite materials of 3:7 mass ratio,initial permeability is 26,Q-value is 19 and e' is 32.
