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 ...
Effect of pore generator on microstructure and resistivity of Sb(2)O(3)and CuO doped SnO(2)electrodes
(Springer, 2020-08-08)
Sb2O3 and CuO doped SnO2 ceramic electrodes could be an alternative to the ones currently used ones in the electrooxidation process of water pollutants. The rise of electrode surface by introducing a porogen agent on the ...
Study of lithium carbonate as sintering aid for tin oxide densification trough experimental designs: Main variables and microstructure changes
(Elsevier, 2022)
Tin oxide is one of the most extensively studied semiconductor materials due to its broad
field of applications. On the one hand, its high conductivity and its corrosion resistance are
the most remarkable properties. ...
Effect of secondary thermal treatment on crystallinity of spinel-type Co(Cr, Al)2O4 pigments synthesized by solution combustion route
(Elsevier, 2018-03)
The effect of a post-synthesis thermal treatment on CoCr2−2ΨAl2ΨO4 (0.0 ≤ Ψ ≤ 1.0) ceramic pigments synthesized by Solution Combustion Synthesis (SCS) has been studied. As-synthesized SCS pigments were treated at two ...
Effect of type and amount of alumina as dopant over the densification and the electrical properties of zinc oxide ceramic electrodes
(Elsevier, 2021-02)
Aluminum-doped zinc oxide (AZO) electrodes can be a good alternative to replace the expensive electrodes (Ti, ITO, FTO, etc.), which are used in the electrooxidation process to remove refractory and emergent contaminants ...
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 ...
Solution combustion synthesis of (Ni,Fe)Cr2O4 pigments: Effect of post-synthesis thermal treatments
(Elsevier, 2017-10-15)
Mixed spinel pigments Ni1− ΨFeΨCr2O4 (0 ≤ Ψ ≤ 1) were synthesized by means of a method known as Solution Combustion Synthesis, using urea as fuel. Effects on mineralogy, microstructure and colouring power of composition ...
Solution combustion synthesis of (Co,Ni)Cr2O4 pigments: Influence of initial solution concentration
(Elsevier, 2017-09)
Initial solution concentration effect was studied on the synthesis of mixed spinels Co1-ΨNiΨCr2O4 (0≤Ψ≤1) obtained by Solution Combustion Synthesis. Fd-3m spinel structure was developed in all range of compositions analysed, ...

(C & M Publicaciones, 2015-01)
El objetivo del proyecto es desarrollar un sistema eficaz para eliminar los nitratos presentes en aguas subterráneas, en procesos de potabilización, transformándolos en nitrógeno mediante una reacción de hidrogenación ...
Comparison of extruded and pressed low cost ceramic supports for microfiltration membranes
(Copyright © Elsevier, 2015)
A comparison has been made between ceramic supports for microfiltration membranes of the same composition obtained by pressing and by extrusion in terms of microstructure and properties.
The extruded supports displayed ...
