BaSnO3 belongs to the family of analogous alkaline-soil stannates
with general stechiometric formula MSnO3 (whereM¼ Ba, Sr,
and Ca). In case of BaSnO3 and CaSnO3, the cubic perovskite
structure is disrupted by octahedral tilting distortion and orthorhombic
crystal structure forms [5].
BaSnO3 powders used to be prepared in solid-state reaction of
BaCO3 and SnO2 at high temperature exceeding 1300 C. However,
these powders contained impurities and were coarse grained [6].
Therefore, various wet chemical syntheses such as hydrothermal
method [7], solegel method [6], and polymerized complex method
[8] have been recently adjusted and applied for the preparation of
the fine BaSnO3 powders.
