| Abstract: | PZT ceramic array was prepared by ceramic powder injection molding.After the array was degreased,sintered,infused with epoxy resin and post processed,1-3 piezoelectric composites with the 4 ～ 5 ratio of length to diameter were prepared and the piezoelectric properties and mechanical-electronical conversion properties were studied.The results indicated that piezoelectric constant was more than 400 pC/N,at the same level with that of piezoelectric ceramic flake.The ratio of the thickness coupling coefficient kt to the radial coupling coefficient kp reached about 2,higher than that of PZT ceramc. |
