Influence of barium and strontium addition on the ratio c/a of PZT obtained by the polymeric precursor method
(2001-11-09)
Lead zirconate titanate powder, with Zr/Ti ratio of 50/50 was prepared by Pechini method after adding up to 10,0 mol% of Ba +2 and Sr +2 ions. Tetragonal phase is favored by the increase of barium and strontium concentration ...
Powder Diffraction of Components Subject to Corrosion in Fuse Cutouts with CeramicInsulation
(Trans Tech Publications Ltd, 2008-01-01)
Aiming identification of the components most affected by corrosion under saline environment conditions, we have carried out X-ray diffraction measurements in ceramic and bond materials, all in the powder form. The ceramic ...

Methanol oxidation on PtRu/C electrocatalysts prepared by a microemulsion method
(2007-12-01)
PtRu/C nanocatalysts were prepared by a microemulsion method using different values of water/surfactant molar ratio in order to get different particle sizes. Crystallite sizes and structural properties were determined by ...
Characterization of hydrochlorothiazide in solid formulations
(2015-03-03)
Hydrochlorothiazide (HCTZ) is a diuretic used for the treatment of blood pressure (hypertension). HCTZ has two anhydrous polymorphs denoted as Forms I and II. Aiming at solid-state characterization, X-ray powder diffraction ...
Reactive sputter magnetron reactor for preparation of thin films and simultaneous in-situ structural study by X-ray diffraction.
(Laboratório Nacional de Luz SíncrotronCampinas, 2013-02-26)
Reactive Sputter Magnetron (RSM) is a widely used technique to thin films growing
of compounds both, in research laboratories and in industrial processes. The nature
of the deposited compound will depend then on the ...
Nanoparticles of La1-xSrxMnO3 compounds
(2002-12-01)
A nanoparticles of La1-xSrxMnO3 were synthesized using homogenous coprecipitation method. The precipate was washed with water and dried at 80 °C. The samples were characterized by X-ray powder diffraction, transmission ...
