Y-TZP zirconia regeneration firing: Microstructural and crystallographic changes after grinding
(2017-01-01)
This study evaluated microstructural and crystallographic phase changes after grinding (G) and regeneration firing/anneling (R) of Y-TZP ceramics. Thirty five bars (Lava™ and Ice Zirkon) were divided: Y-TZP pre-sintered, ...
ZnO-TiO2 composite formed by mixed oxides via polyol
(Trans Tech Publications Ltd, 2012-01-01)
Among the researches on preparation and test of nanostructured materials, titanium dioxide and zinc oxide have been the most frequent studied oxides. In order to extend their properties, composites have been prepared using ...

Thermal stability analysis of Cu-11.8 wt%Al milled samples by TEM and HT-XRD
(Elsevier Science, 2017-10)
In this work, the thermal stability of two samples of Cu-11.8 wt%Al obtained by different milling processes is analyzed. Several TEM techniques were used and HT-XRD experiments performed to determine the crystal structure ...
EXAFS and XRD Study of the Structural Evolution during Isothermal Sintering of SnO2 Xerogels
(1997-12-01)
The formation of an ordered (crystalline) phase during isothermal sintering of SnO2 monolithic xerogels, at 200, 250, 300, 400, 500, 600 and 700°C, has been analyzed by the combined use of EXAFS and XRD techniques. For the ...

Corrosion behavior of WC-Co coatings deposited by cold gas spray onto AA 7075-T6
(2018-01-01)
This work reports a morphological, mechanical, and corrosion resistance characterization of WC-12Co and WC-25Co coatings deposited by cold gas spray (CGS) onto AA 7075-T6 alloy. Cross-sectional images of the coatings ...
Chemical and mineralogical characterization of Aguada Portezuelo pottery from Catamarca, north-western Argentina: PIXE, XRD and SEM-EDS studies applied to surface pre- and post-firing paints, slips and pastes
(Wiley Blackwell Publishing, Inc, 2020-04-16)
Particle-induced X-ray emission (PIXE), X-ray diffraction (XRD), electron microprobe analysis (EDS) and scanning electron microscopy (SEM) analytical techniques were used to characterize surface paints in pre- and post-fired ...
Study of the structural order of native starch granules using combined FTIR and XRD analysis
(2018-12-01)
The structural order of native starch granules with different crystalline patterns was analyzed by combined X-ray diffraction (XRD) and Fourier transform infrared spectroscopy (FTIR) and the results were compared to that ...
SR-XRD in situ monitoring of copper-IUD corrosion in simulated uterine fluid using a portable spectroelectrochemical cell
(Elsevier Science Sa, 2016-08)
The objective of this work is to study the initial corrosion of copper in the presence of gold when placed in simulated uterine fluid in order to better understand the evolution of active components of copper-IUDs. In order ...
