Effect Of Sintering Temperature on the Dielectric Properties of Pb(Zr_(0.52)Ti_(0.48))O_3 Ceramics Synthesized via High Planetary Ball Mill

摘要

The properties of Pb(Zr_(0.52)Ti_(0.48))O_3 (PZT) ceramics have been studied. PZT ceramic powders were successfully prepared by high planetary ball mill method under different milling time and then were sintered at different sintering temperature. The raw materials of PbO, ZrO_2 and TiO_2, powders were ball milled at 40 and 60 hours using high planetary mill. The mixing powders then were compacted and sintered at 950°C and 1200°C. Formations of the perovskite phase along with some secondary phase were seen after 40 and 60 hours of milling while single phase formation of PZT was seen after sintered at both sintering temperatures. The grain size of the samples becomes larger with the increasing temperature. In dielectric properties analysis, the dielectric constants were reduced due to increasing sintering temperature. Meanwhile, the loss tangents increased with sintering temperature.
