During calcination, the desired bismuth-layered structure phase develops at the expense of the pyrochlore phase. Calcining the precursor powder at 750¢XC for 2 h leads to the complete formation of single-phase layered-structured SrBi2Ta2O9. The powder that is formed consists of nanoparticles with a narrow size distribution and almost-spherical morphology. The crystallinity of the calcined powder increases as the calcination temperature and heating time increases. The developed colloid-emulsion process significantly reduces the SrBi2Ta2O9 particle size, in comparison to conventional process techniques, and results in a uniform microstructure of the obtained powder.journal article10.1111/j.1151-2916.2000.tb01382.x2-s2.0-0033747722https://www.scopus.com/inward/record.uri?eid=2-s2.0-0033747722&partnerID=40&md5=08daaefc13d81f8b95fe9f00e00dadeb
