Abstract
Lattice constants and temperatures corresponding to maximum dielectric permittivity were investigated for compositions in the barium titanate‐rich portion of the system barium titanate–barium stannate–strontium titanate. Substitution of tin for titanium increases the lattice constant at room temperature, and substitution of strontium for barium decreases this parameter. Both types of substitution decrease the Curie temperature; tin is about twice as effective as strontium in this regard. Properties of bodies containing both tin and strontium are intermediate between those of bodies containing either alone.
