Paper Title:
Preparation and Relaxor Behavior of Barium Strontium Titanate Glass-Ceramics Doped Si-B-O Sintered from Sol-Gel Derived Powders
  Abstract

The structural and dielectric properties of Si-B-O doped Ba0.60Sr0.40TiO3 (BST) glass-ceramics prepared by using sol-gel derived powders have been investigated. The secondary phase of BaTi2Si2O8 is clearly observable in BST glass-ceramics when the concentration of Si-B-O is equal to or more than 20mol%. The samples with high Si-B-O doping levels can be sintered into dense microstructure in low sintering temperature (below 1000°C). The dielectric peaks of BST glass-ceramics are markedly suppressed, broadened and shifted to low temperature with increasing the concentration of Si-B-O, accompanying an increased diffuseness of the dielectric peak due to the ionic substitution, which follows well the Lorenz-type relation.
