The secondary phase compositions in Sb-doped (Ba, Sr)TiO3ceramics containing SiO2and excess TiO2sintering additives have been examined by XRD, BEI and EPMA techniques. It is shown that alongside the primary (Ba0.797Sr0.2Sb0.003) TiO3phase, (Ba1.95Sr0.05)2(Ti1.2Si1.8)O8and Sb-doped (Ba0.99Sr0.01)6Ti1...
