Structural and dielectric studies in the (Ba0.9Ca0.1)(Ti1−xSn x )O3 system

The variation in lattice constant and dielectric constant in the (Ba0.9Ca0.1) (Ti1−xSn x )O3 system have been investigated for compositions fromx = 0 tox = 0.20. Thea axis lattice constant increases at room temperature as substitution of tin for titanium increases, while thec axis lattice constant decreases. The dielectric constant increases and the Curie temperature is shifted to lower temperature as the amount of tin increases.
