摘要

Ferroelectric glass-ceramics of composition 0.90 (Ba_(0.7)Sr_(0.3) TiO_3-0.10(B_2O_3:SiO_2) (0.90 BST:0.10 BS) synthesized by sol—gel method have been used for the preparation of dielectric thick-film inks. The particle dispersion of the glass—ceramic powders in the thick-film ink formulations have been studied through rheological measurements for fabricating thick-film capacitors by screen printing technique. The thick films derived from such glass—ceramics are found to sinter at considerably lower temperatures than the pure ceramic, and exhibit good dielectric characteristics with a tunability of 32% at 1 MHz under a dc bias field of 35 kV/cm.
