Synthesis and Electrophysical Properties of Ba(Ti, Sn)TiO3 and (Ba, Nd)TiO3 Solid Solutions

Ba(Ti, Sn)TiO3 and (Ba, Nd)TiO3-based solid solutions were synthesized using the solid-state reaction technique. The sequence of phase transformations during synthesis was established. Crystallographic parameters and microscopy were studied. Changes in crystallographic parameters and average grain size with substitution degree were determined. It was found that the introduction of 0.5 wt% manganese oxide (IV) and 2 wt% of low-melting glass AST (Al2O3-SiO2-TiO2) reduces the sintering temperature and improves the dielectric parameters (epsilon and tan(delta)). It has been shown that the obtained materials are promising for the development of ceramic capacitors.
