Analysis on Electrical Properties of BST Based Ceramic Condenser

BST계 세라믹 콘덴서의 전기적 특성 분석

This paper was presented to BaTiO$_3$-SrTiO$_3$(BST) ceramic capacitor in using high voltage. Structural and electrical properties of BST ceramic capacitor were researched in accordance with SrTiO$_3$ contents. As the result of investigation, the BST1 ceramic capacitor was showed to stable dielectric properties between 25 and 85[$^{\circ}C$]. According as frequency was increased, relative permittivity was decreased because inner spontaneous polarizations were decreased. As supplied voltage was increased, relative permittivity of specimen was varied in 3.04 ~3.98[%].
