Femtosecond third-harmonic generation in a glass ceramic containing sodium niobate nanocrystals
(OPTICAL SOC AMER, 2011)
The third-harmonic optical susceptibility, chi((3))(3 omega; omega, omega, omega) of a silicate glass ceramic containing sodium niobate nanocrystals was measured for incident broadband light with central frequency omega ...
New insights into the properties of KxNa(1-x)NbO3 ceramics obtained by hydrothermal synthesis
(Elsevier, 2014-06-18)
Different reaction conditions for the hydrothermal synthesis of KxNa(1-x)NbO3 (KNN) were studied. Samples were synthesized at 190°C in a Teflon lined autoclave and the effects of different KOH/(KOH+NaOH) ratios (0 to 0.8) ...
New dielectric anomalies in the A-site highly deficient NaxNbO3 electroceramics
(Elsevier, 2020)
Highly sodium deficient Na0.6NbO3 (NN) ceramics were prepared and characterized. Their mean structure could be described by a mixture of the predominant P polymorph (S.G. Pbma) and the Q phase (S.G. P2(1)ma), at room ...
Dielectric loss and phase transition of sodium potassium niobate ceramic investigated by impedance spectroscopy
(Elsevier B.V., 2003-02-28)
The dielectric permittivity of Na0.80K0.20NbO3 ceramic was investigated by impedance spectroscopy. The dielectric characterization was performed from room temperature to 800 degreesC, in the frequency range 5 Hz-13 MHz. ...
Structural characterization and Curie temperature determination of a sodium strontium niobate ferroelectric nanostructured powder
(Academic Press Inc. Elsevier B.V., 2011-05-01)
The Curie temperature and its correlation with the magnitude of the displacement of the niobium atom from the center of [NbO6] octahedra in NaSr2Nb5O15 nanostructured powder were investigated. A single powder was prepared ...
