초록
PZT powders were prepared by the molten salt synthesis method. The porous PZT was preapred from the mixture of PZT and PVA powders by BURPS(BURnout plastic Sphere) technique. The acoustic properties with various plastic sphere wt.% were studied. The acoustic impedance of porous PZT was smaller than that of single phase PZT ceramics. And the pulse-reponse of porous PZT maded transducer was significantly advanced to that of solid PZT maded transducer.
