Title: | Sol-gel (combustion) synthesis and characterization of different alkaline earth metal (Ca, Sr, Ba) stannates | Authors: | STANULIS, Andrius Sakirzanovas, Simas VAN BAEL, Marlies Kareiva, Aivaras |
Issue Date: | 2012 | Publisher: | SPRINGER | Source: | JOURNAL OF SOL-GEL SCIENCE AND TECHNOLOGY, 64 (3), p. 643-652 | 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. | Notes: | [Stanulis, Andrius; Kareiva, Aivaras] Vilnius State Univ, Dept Gen & Inorgan Chem, LT-03225 Vilnius, Lithuania.
