LiCO₃가 첨가된 (Ba<SUB>0.5</SUB>Sr<SUB>0.5</SUB>)TiO₃ 후막의 전기적 특성 = Electric Properties of LiCO₃ doped (Ba<SUB>0.5</SUB>Sr<SUB>0.5</SUB>)TiO₃ Thick Films

다국어 초록 (Multilingual Abstract)

Li₂CO₃ doped Ba<SUB>0.5</SUB>Sr<SUB>0.5</SUB>TiO₃ ceramics were fabrication by sol-gel method. Sintering temperature must be suited to the LTCC technology. Structure and dielectric properties were investigated for effect of Li₂CO₃ dopants at BST. Structure of Li₂CO₃ doped Ba<SUB>0.5</SUB>Sr<SUB>0.5</SUB>)TiO₃ ceramics were dense and homogeneous with almost no pore. Relative permittivity was decreased and dielectric loss was increased with increasing Li₂CO₃ doping rations. In the case of the 3wt% Li₂CO₃ doped Ba<SUB>0.5</SUB>Sr<SUB>0.5</SUB>)TiO₃ ceramics sintered at 900℃, relative permittivity and dielectric loss were 907 and 0.003 at 100 ㎑.
