자전연소반응법에 의해 제조된 PZT의 전기적 특성에 미치는 Sr의 영향 = Effects of Sr on the Electrical Properties of PZT Ceramics Prepared by Self-propagating High-temperature Synthesis

다국어 초록 (Multilingual Abstract)

PSZT are selected and SHS are applied to each system. The sintering properties of PSZT powders showed $7.754g/cm^3$ of sintered density and $4{\mu}m$ of grain size at sintering temperature of $1250^{\circ}C$. Curie temperature lowered gradually from $363.6^{\circ}C\;to\;319.2^{\circ}C$ and relative dielectric constants increased rapidly by a quantity of Sr. This remarkable contrast in dielectric properties with powder preparation methods, in this study, was not due to grain size and sintered density but rather a crystallinity and sinterability of synthesized powders, extra-supplied Pb during reaction, mol fraction of rhombohedral phase and purity of starting materials.
