The effect of particle size on the phase transformation of the prepared NaNbO(3) powders was studied using X-ray powder diffraction, Raman spectroscopy, and nuclear site group analysis based on these spectroscopic data. Coarsened particles exhibit an orthorhombic Pbcm (D(2h)(11), no. 57) structure corresponding to the bulk structure, as observed for single crystals or powders prepared by conventional solid-state reaction. The crystal symmetry of submicron powders was refined with the space group Pmc2(1) (C(2v)(2), no. 26). The reduced perovskite cell volumes of these submicron powders were most expanded compared to all the other structures. Fine particles with a diameter of less than 70 nm as measured from SEM observations showed an orthorhombic Pmma (D(2h)(5), no. 51) crystal symmetry. The perovskite formula cell of this structure was pseudocubic and was the most compact one. A possible mechanism of the phase transformation is suggested. 000055901 536__ $$0G:(DE-Juel1)FUEK257$$2G:(DE-HGF)$$aChemie und Dynamik der Geo-Biosphäre$$cU01$$x0 000055901 588__ $$aDataset connected to Pubmed 000055901 7001_ $$0P:(DE-Juel1)VDB22119$$aMagrez, A.$$b1$$uFZJ 000055901 7001_ $$0P:(DE-Juel1)129189$$aDornseiffer, J.$$b2$$uFZJ 000055901 7001_ $$0P:(DE-HGF)0$$aHaegel, F.-H.$$b3 000055901 7001_ $$0P:(DE-Juel1)130894$$aPithan, C.$$b4$$uFZJ 000055901 7001_ $$0P:(DE-Juel1)131022$$aWaser, R.$$b5$$uFZJ 000055901 773__ $$0PERI:(DE-600)2006039-7$$a10.1021/jp052974p$$gVol. 109, p. 20122 - 20130$$p20122 - 20130$$q109<20122 - 20130$$tThe @journal of physical chemistry <Washington, DC> / B$$v109$$x1520-6106$$y2005 000055901 8567_ $$uhttp://dx.doi.org/10.1021/jp052974p 000055901 909CO $$ooai:juser.fz-juelich.de:55901$$pVDB 000055901 9131_ $$0G:(DE-Juel1)FUEK257$$bEnvironment (Umwelt)$$kU01$$lChemie und Dynamik der Geo-Biosphäre$$vChemie und Dynamik der Geo-Biosphäre$$x0 000055901 9141_ $$y2005 000055901 915__ $$0StatID:(DE-HGF)0010$$aJCR/ISI refereed 000055901 9201_ $$0I:(DE-Juel1)VDB321$$d31.12.2006$$gIFF$$kIFF-IEM$$lElektronische Materialien$$x1 000055901 9201_ $$0I:(DE-Juel1)VDB48$$d31.12.2006$$gICG$$kICG-II$$lTroposphäre$$x2 000055901 970__ $$aVDB:(DE-Juel1)87240 000055901 980__ $$aVDB 000055901 980__ $$aConvertedRecord 000055901 980__ $$ajournal 000055901 980__ $$aI:(DE-Juel1)PGI-7-20110106 000055901 980__ $$aI:(DE-Juel1)IEK-8-20101013 000055901 980__ $$aUNRESTRICTED 000055901 981__ $$aI:(DE-Juel1)ICE-3-20101013 000055901 981__ $$aI:(DE-Juel1)PGI-7-20110106 000055901 981__ $$aI:(DE-Juel1)IEK-8-20101013
