Low temperature sintering of BaxSr1−xTiO3 glass-ceramic
Source abstract
Abstract
The sintering temperature of Ba x Sr 1-x TiO 3 (BST) ceramic prepared by conventional method is too high (1350-1400°C) [Mater. Sci. Semicond. Process. 5 (2003) 215] to co-fire with high-conductive and low-melting temperature conductors, such as Ag. In this paper, Ba-Sr-Ti-Pb-B-Si-O gel-glasses were prepared by sol-gel process. BST crystalline grains grew out from an amorphous gel-glass matrix at proper heat treatment temperatures. Because of the glass content, the sintering temperature of BST can be decreased below 1000 °C. Because Pb 2+ substituted Ba 2+ and Sr 2+ in the perovskite lattice forming PbTiO 3 . The Curie temperature of BST glass-ceramic was higher than that of the pure Ba x Sr 1-x TiO 3 ceramic. The effect of the amount and composition of Pb-B-Si-O glass on BST was studied and presented in this paper.
