Pengaruh Perbedaan Tekanan terhadap Proses Pemolingan Bahan Piezoelektrik Pbzr0,52ti0,48o3 dengan Penambahan Polyvinylidine Flouride

Abstract

It has been synthesized a piezoelectric ceramic material Plumbum Zirconate Titanate (PZT) is the material that contains elements PbZr0,52Ti0,48O3. This research was carried out by grinding, compacting with variations of pressure of 35.150 N/m2 and 49.210 N/m2, and heating at a temperature of 950oC for 4 hours so-called solid state reaction. After the synthesis process has been done the characterization materials using X-ray diffractometer (XRD) and Brunauer, Emmet, Teller (BET). The result of identification using XRD shows that the synthesis product had a tetragonal crystal structure of perovskite. The good PZT will be crushed again with the addition of gram PVDF fraction of 1,5% and 2,5% for PZT pressure of 35.150 N/m2 and 5% for PZT pressure of 49.210 N/m2. Then proceed with the process of polling with the voltage 4 kV/mm using a high voltage of source series of TV 14-21 inches. The success of the process of polling proved by measurements of the piezoelectric constants using d33 meter. The results of the highest piezoelectric constants obtained from PZT material piezoeletrik 49.210 N/m2 pressure is 61 x 10-12 C/N. The addition of PVDF on PZT reduce piezoelectric’s constant value.
