A comparative study of different solvothermal methods for the synthesis of Sn2+-doped BaTiO3 powders and their dielectric properties
Source abstract
Abstract
Ternary oxides containing Sn2+ are rare and difficult to prepare by the conventional solid state reactions due to the disproportionation of Sn2+ to Sn4+ and Sn at high temperatures. In this article, Sn2+-doped barium titanate, Ba1−xSnxTiO3 (x = 0.00, 0.02, 0.05, and 0.10) nanopowders were successfully synthesized at a moderate temperature by a microwave-assisted solvothermal reaction (MSR) and a solvothermal reaction with rolling (SRR). The powders obtained using the MSR and SRR consisted of nanoparticles of 20–50 nm and 100–120 nm in diameter, respectively. The dielectric constant of the sample increased by doping with a small amount of Sn2+ (x ≤ 0.05), but decreased by doping in excess amounts of it.
