Structural and Dielectric Properties of BST-MgO with $B_2O_3-Li_2CO_3$ Thick Films

$B_2O_3-Li_2CO_3$가 첨가된 BST-MgO 후막의 구조 및 유전 특성

At first the $Ba_{0.5}Sr_{0.5}TiO_3$-MgO powder with $B_2O_3-Li_2CO_3$ were made by the Sol-Gel method. The thick films of BST-MgO with $B_2O_3-Li_2CO_3$ were fabricated on the $Al_2O_3$ substrates coated with Pt by the screen printing method. The structural and dielectric properties of the BST-MgO thick film with $B_2O_3-Li_2CO_3$, addition were investigated. The structure of the BST-MgO with $B_2O_3-Li_2CO_3$ thick films were dense and homogeneous with no pores. The dielectric constant was increased and dielectric loss was decreased with increasing the sintering temperature.
