초록

$(Ba_{0.6-x}-Sr_{0.4}Ca_x)TiO_3$ (x=0.10, 0.15, 0.20, y=$0.0{\sim}3.0$) powders were fabricated by the sol-gel method, and BSCT thick films were fabricated by the silk-screen printing method. Their structural and dielectric properties were investigated with variation of composition ratio. All BSCT thick films showed a homogeneous structure without presence of the second phase. BSCT film thickness, obtained by three cycle of printing, was approximately $80{\mu}m$. The dielectric constant and dielectric loss of the 3-coated BSCT(50/40/10) thick film were approximately 1700 and 0.07%, respectively.
