Abstract: In this study, monophasic strontium and barium stannate (SrSnO3, Sr2SnO4, BaSnO3, Ba2SnO4) powders were synthesized by means of environmentally friendly aqueous sol-gel technique under neutral conditions. However, it was established that the successful sol-gel synthesis of appropriate calcium stannates (CaSnO3 and Ca2SnO4) can be performed only at acidic sol-gel processing conditions. Moreover, the influence of nature of alkaline earth metal source on the phase purity of different metal stannates was evaluated. The thermal behaviour of Ca-Sn-O, Sr-Sn-O and Ba-Sn-O precursor gels was investigated by TG-DSC measurements. The phase purity, crystallization peculiarities and microstructural evolution of the sol-gel derived alkaline earth metal stannate powders were studied by XRD and SEM measurements.
