|Issue Date:||Oct-1993||Citation:||Chuah, G.K., Jaenicke, S., Chan, K.S., Khor, S.T., Hill, J.O. (1993-10). A thermal analysis evaluation of the low temperature synthesis of BaBiO3.

ScholarBank@NUS Repository. https://doi.org/10.1007/BF02546878||Abstract:||Thermal decomposition of metal-organic precursors for the mixed oxide BaBiO3 was studied using TG and EGA. Precursors produced by polyesterification of bifunctional acids with ethylene glycol (Pechini process) decomposed about 100°C higher than those without the diol. BaCO3 was identified by IR and XRD as a reaction intermediate. EGA proved that the amount of BaCO3 was below 10% of the total barium, and that the barium exists mainly as a nitro-compound up to 650°C. Phase-pure BaBiO3 with a moderately high surface area (1.4 m2/g) could be synthesised from a citrate precursor by the Pechini process at around 850°C. © 1993 John Wiley & Sons, Limited and Akadémiai Kiadó.||Source Title:||Journal of Thermal Analysis||URI:||http://scholarbank.nus.edu.sg/handle/10635/93022||ISSN:||03684466||DOI:||10.1007/BF02546878|
