Abstract.

Thermochim. Acta 441 (2006) 176-183. (DOI: 10.1016/j.tca.2005.12.010).

The thermal behaviour of [Ba(C2H6O2)4][Sn(C2H4O2)3] used as a BaSnO3 precursor, and its phase evolution during thermal decomposition are described. The initially formed transient barium-tin-oxycarbonate phase disintegrates into BaCO3 and SnO2, reacting subsequently to BaSnO3. The existence of the intermediate oxycarbonate phase is evidenced by FT-IR, XRD, and EELS (ELNES) investigations.
