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 ...
Electronic structure and optical properties of BaMoO4 powders
(Elsevier B.V., 2010-03-01)
Barium molybdate (BaMoO4) powders were synthesized by the co-precipitation method and processed in microwave-hydrothermal at 140 degrees C for different times. These powders were characterized by X-ray diffraction (XRD), ...
Preparation of 9.5/65/35 PLZT powders by organic precursor method
(2001-01-01)
In this study the preparation of 9.5/65/35 PLZT ceramic powders were investigated. The powders with the formula Pb0.905La0.095(Zr0.65 Ti0.35)0.976O3 + 3.5 w% PbO were prepared using Pechini process and partial oxalate ...
Effect of powder milling and dopant addition on the current-voltage characteristics of SnO2-based ceramics
(2001-01-01)
Non-linear electrical properties of SnO2-based ceramics were investigated as a function of powder agglomeration condition and as a function of dopant addition. All doped powders presented a single phase, cassiterite, as ...
Photoluminescent properties of lead zirconate powders obtained by the polymeric precursor method
(Elsevier B.V., 2012-08-01)
Lead zirconate powders, obtained by the polymeric precursor method, were annealed for 2 h at temperatures from 300 to 800 degrees C. The effect of heat treatment on structural defects and photoluminescent behavior was ...
Structural effects of Li and K additives on the columbite precursor and 0.9PMN-0.1PT powders
(Elsevier B.V., 2004-03-15)
Single-phase perovskite 0.9Pb(Mg1/3Nb2/3)O-3-0.1PbTiO(3) (PMN-PT) powders were prepared by using a Ti-modified columbite precursor (MNT) obtained by the polymeric precursor method. The innovation consists in the preparation ...
Synthesis and sintering of ultra fine NaNbO3 powder by use of polymeric precursors
(1996-09-01)
Ultra-fine NaNbO3 powder was prepared by the use of polymeric precursors. X-ray diffraction (XRD) results showed that this niobate nucleates from the amorphous precursor, with no intermediate phases, at low temperature ...
The Physical and Morphological Characteristics of Mango Powder (Mangifera indica L. cv Tommy Atkins) Produced by Foam Mat Drying
(2017-03-01)
The thermal behavior, moisture adsorption properties and structural and morphological characteristics of mango powders were evaluated. The powders were obtained by foam mat drying methodology using albumin (ALB), mixture ...
