Abstract
The effect of WO3 doping on the dielectric temperature characteristics and
the microstructure of a ternary ceramic system were investigated. Both the
increase of WO3 doping level and the increase of sintering temperature led
to a decrease in dielectric constant and the flatting of dielectric curves.
The presence of a liquid phase and the pyrochlore phase cause this decreas
e. Also, microstructural and elemental analyses of the ceramics revealed th
e structure within one grain consists of three parts: the core, the shell a
nd in-between one. This inhomogeneous composition distribution contributes
to flat dielectric temperature dependence. (C) 2001 Elsevier Science B.V. A
