The effect of Li-substitution on the M-phases of AgNbO3./sub

Popis výsledku v původním jazyce

Ceramics in the solid solution, LixAg1-xNbO3 (LAN) with 0 <= x <= 0.20, have been synthesized by the mixed oxide method. X-ray diffraction (XRD) revealed that only compositions with x <= 0.05 were single phase which were indexed according to Pbcm symmetry with a unit cell, root 2a(p) x root 2a(p) x 4a(p) (where a(p) is the fundamental perovskite lattice parameter). For compositions with x >= 0.1, second phase peaks attributed to LiNbO3 were observed and the matrix phase transformed to a metrically rhombohedral structure according to XRD. A phase transition at 0.05 < x <= 0.1 was confirmed by Raman spectroscopy and electron diffraction but the latter technique revealed superstructure reflections for x >= 0.1 at +/- 1/6{00l} and 1/2{ooo} +/- 1/6{00l} (where o = odd). These support the premise that Li doping invokes a new complex modulated tilt system with a root 2a(p) x root 2a(p) x 6a(p) unit cell rather than root 2a(p) x root 2a(p) x 4a(p) (Pbcm). Reflections of the type +/- 1/6{00l} a
