Solid solutions of barium titanate-stannate, Ba(Ti,Sn)O3 have been investigated. The sequence of phase transformations during the synthesis by solid state reactions technique has been determined, crystallographic and microscopic examinations of polycrystalline ceramics based on Ba(Ti,Sn)O3 solid solutions have been carried out. The laws governing the change in crystallographic parameters and the average grain size as a function of tin content have been shown. Electrophysical investigations of the obtained ceramics have been carried out. It has been found that the dielectric pa-rameters (e and tgd) of Ba(Ti,Sn)O3-based ceramics can be improved and their sintering temperature can be reduced by the addition of 0.5 wt.% manganese oxide(IV) and 2 wt. % of low-melting glass-forming admixture AST (Al2O3–SiO2–TiO2). It has been shown that the obtained materials have promise in creating ceramic capacitors based on them. |
