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 of the Electrochemical Behavior of (Sb, Sn, Cu)O Ceramic Electrodes as Electrochemical Advanced Oxidation Anodes
(Wiley, 2019-05-02)
This work explores the possibility of increasing the active surface of a Sb‐doped SnO2 ceramic electrode using CuO as sintering aid, by incorporating petroleum coke as a pore generator. In order to fulfil this goal, three ...
Evaluation of the Dustiness of Different Kaolin Samples
(Taylor & Francis, 2015)
Several samples of kaolin with different mean particle size were prepared and tested using the continuous drop method, one of the reference test methods according to standard EN 15051:2006 “Workplace atmospheres – Measurement ...
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 ...
Bioactive glass suspensions preparation for suspension plasma spraying
(Elsevier, 2016-06)
A bioactive glass was dry-milled and sieved in order to obtain powders with particle size finer than 63 μm. Two suspensions, with different particle size distribution (D50 = 8.3 μm and D50 = 2.2 μm), were subsequently ...
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 ...
Sinter-crystallisation kinetics of a SiO2–Al2O3–CaO–MgO–SrO glass-ceramic glaze
(Elsevier, 2020-03-15)
This paper examines the microstructural development and kinetics of the sintering and crystallisation processes of a SiO2–Al2O3–RO (R = Ca, Mg, Sr) glass-ceramic glaze. Crystallisation and sintering kinetics were studied ...
Iron zircon pigment synthesis: Proposal of a mixing index for the raw materials mixtures
(ElsevierSociedad Española de Cerámica y Vidrio, 2017)
Iron zircon coral pigments are very interesting from an industrial point of view because of their high colouring power and their stability at high temperatures. However, the pigment's synthesis is particularly troublesome ...
Fuel effect on solution combustion synthesis of Co(Cr,Al)2O4 pigments
(Elsevier, 2017-10)
The fuel effect on the synthesis of a ceramic pigment with a composition CoCr2−2ΨAl2ΨO4 (0 ≤ Ψ ≤ 1) by means of solution combustion synthesis process (SCS) has been studied. Three different fuels were selected to carry out ...
Improvement of salicylic acid biological effect through its encapsulation with silica or chitosan
(Elsevier B.V., 2021-12-30)
Attacks of necrotrophic and biotrophic fungi affect a large number of crops worldwide and are difficult to control
with fungicides due to their genetic plasticity. Encapsulation technology is a good alternative for ...
