Effects of composition and furnace temperature on (Ni, Co) (Cr, Al)2O4 pigments synthesized by solution combustion route
(Wiley, 2017-08)
The effects of composition and furnace temperature on Ni1-ΨCoΨCr2−2ΨAl2ΨO4 (0≤Ψ≤1) pigments prepared by Solution Combustion Synthesis were studied. As-synthesized samples showed spinel-like spongy structure, very easy to ...
Anion transport through ceramic electrodialysis membranes made with hydrated cerium dioxide
(Wiley, 2017-05)
In this research, low-cost ceramic anion-exchange membranes have been developed from porous supports manufactured, using a chamotte as a pore former. An inorganic anion-exchanger (hydrated cerium dioxide) has been deposited ...
Effect of fluorine and nitrogen content on the properties of Ca-Mg-Si-Al-O-(N)-(F) glasses
(Elsevier, 2017)
X-ray amorphous glasses of composition (in equivalent percent) 15Ca:15Mg: 55Si:15Al:(100-x-y)O:xN:yF with x=0, 10, 15 and y=0, 1, 3, 5, were prepared by melting and casting. The effects of oxygen substitution by fluorine ...
Comparison of porosity assessment techniquesfor low-cost ceramic membranes
(Sociedad Española de Cerámica y Vidrio, 2017-01)
En el presente trabajo se han caracterizado mediante diferentes métodos membranas cerámicas de bajo coste desarrolladas para tratar aguas residuales en reactores biológicos de membrana (MBR) o mediante tratamientos terciarios. ...
ZnO and CuO crystal precipitation in sintering Cu-doped Ni-Zn ferrites. II. Influence of sintering temperature and sintering time
(Elsevier, 2017-01)
This paper presents a study of the precipitation of ZnO and CuO crystals during the sintering of Cu-doped Ni-Zn ferrites. The nature of the resulting crystal precipitates were analysed using scanning electron microscopy ...
Thermal behaviour of multilayer and functionally-graded YSZ/Gd2Zr2O7 coatings
(Elsevier, 2017)
Zirconates with pyrochlore structure, such as Gd2Zr2O7, are new promising thermal barrier coatings because of their very low thermal conductivity and good chemical resistance against molten salts. However, their coefficient ...
Improvement in Char Strength with an Open Cage Silsesquioxane Flame Retardant
(MDPI, 2017)
Different characterization techniques were used to study the hydrolysis and condensation
reaction kinetics of 3-methacryloxypropyltrimethoxysilane (MAPTMS) to obtain open cage
silsesquioxane oligomers. The formation of ...
Investigation of deformation behavior and fracture of ceramic coatings by the acoustic emission method
(Springer Verlag, 2017-03)
The use of protective coatings on components of machines and mechanisms provides the greatest economic benefit at the lowest additional cost. Plasma spraying is one of the most productive, technologically advanced, and ...
Ceria-doped scandia-stabilized zirconia (10Sc2O3·1CeO2·89ZrO2) as electrolyte for SOFCs: Sintering and ionic conductivity of thin, flat sheets
(WileyThe American Ceramic Society, 2017-03)
In this study, thin, flat sheets, about 90 μm thick, were prepared from ceria-doped scandia-stabilized zirconia with molecular formula 10Sc2O3·1CeO2·89 ZrO2 (10Sc1CeSZ) by tape casting and subsequent sintering at different ...
Compositional effects on the crosslink density of Ca–(Mg)–(Y)–Si–Al–oxyfluoronitride glasses
(Wiley, 2017-09)
The effects of fluorine and nitrogen substitution for oxygen in aluminosilicate glasses, effectively oxyfluoronitride (OFN) glasses, modified by calcium, calcium–yttrium or calcium–magnesium on thermal and physical/mechanical ...
