碩士 === 南台科技大學 === 電子工程系 === 98 === This research take the composition of Lead Zirconate Titanate as the object of study, grindingLead Zirconate Titanate into nanometer powder,mixing Lead Zirconate Titanate according to the different weight ratio, then pressing the powder into test pieces, putting them in the heating furnace .After taking out, test its each characteristic, this article will use the testing pieces of different proportion nanometer powder to discuss the influence on Lead Zirconate Titanate (PZT) piezoelectric ceramics and piezoelectricity characteristics, under the different pressure, the temperature, After grinding the nanometer into powder ,mix it by (C100/F0) (C75/F25) (C50/F50) (C25/F75) (C0/F100) , C means the thick powder, F means the thin powder. During the long time test, the composition proportion of (C50/F50) is pressed into the diameter laminated shape pieces by the 600Kg/cm2 pressure, in the 1250 degree high temperature agglutinations, the thick and thin powder can be united closerly, cause the density be above 95% to theory density, namely above 7.6g/cm3, therefore, the (C50/F50) powder may obtain the better polarized effect and the piezoelectricity characteristic.
