The influence of green microstructure and sintering parameters on precipitation process during copper-nickel-zinc ferrites sintering
(Elsevier, 2014-04)
Microstructural changes that occur during heat treatment of copper-nickel-zinc ferrites have been studied. The process of precipitation of the two types of crystals that occur during the sintering process has been analyzed. ...
Polishing of Porcelain Tiles in Industrial- and Laboratory-scale
(German Ceramic Society, 2013)
This work reports the design and use of a laboratory-scale tribometer and a new developed tool-holder to reproduce the industrial polishing process for ceramic tiles in laboratory-scale. The mechanical conditions in a ...
Obtainment of bactericidal inkjet inks based on Ag-nanocomposites
(German Ceramic Society, 2013)
In this study, ceramic inks were formulated that are able to develop bactericidal properties and are appropriate for application by inkjet printing. These inks contain silver nanocomposites and are applied on to unfired ...
Microstructure and indentation mechanical properties of YSZ nanostructured coatings obtained by suspension plasma spraying
(Elsevier, 2013-04)
A commercial nanosuspension of yttria-stabilised zirconia (YSZ) was successfully deposited on austenitic stainless steel substrate by suspension plasma spraying technique (SPS). A SG-100 torch with internal radial injection ...
Properties of Ca–(Y)–Si–Al–O–N–F Glasses: Independent and Additive Effects of Fluorine and Nitrogen
(John Wiley & Sons, 2013)
Thirty glasses of composition (in equivalent percent) 20-xCa:xY:50Si:30Al:(100-y-z)O:yN:zF, with x = 0, 10; y = 0, 10, 20, and z = 0, 1, 3, 5, 7 were prepared by melting and casting. All glasses were X-ray amorphous. Glass ...
Improvement of the mechanical and aesthetic properties of a coating by inkjet technology
(WileyAmerican Ceramic Society, 2021-01-11)
Different amounts of ink, made up almost entirely of a frit that devitrified abundant small crystals of anorthoclase, were applied by inkjet printing onto a traditional unfired glaze substrate. The rheological properties ...
Dispersion of mixtures of submicrometer and nanometre sized titanias to obtain porous bodies
(Elsevier, 2013-12)
The stability and rheological behaviour of bimodal titania suspensions was studied. Bimodal mixtures were prepared by mixing nanosized TiO2 powders with an average primary size of ∼20–40 nm and surface area of ∼50 m2 g−1 ...
Large scale synthesis of nanostructured zirconia-based compounds from freeze-dried precursors
(Elsevier, 2013)
Nanocrystalline zirconia powders have been obtained at the multigram scale by thermal decomposition of precursors resulting from the freeze-drying of aqueous acetic solutions. This technique has equally made possible to ...
Factors Controlling Properties of Ca-Mg, Ca-Er, Ca-Nd, or Ca-Y-Modified Aluminosilicate Glasses Containing Nitrogen and Fluorine
(John Wiley & Sons, 2013)
Glasses with composition (in eq.%) (30 − x)Ca:xM:55Si:15Al:80O:15N:5F have been prepared with different levels of substitution of Ca2+ cations by Mg2+, Y3+, Er3+, or Nd3+. The properties of these glasses are examined in ...
Influence of Particle Size on the Drying Kinetics of Single Droplets Containing Mixtures of Nanoparticles and Microparticles: Modeling and Pilot-Scale Validation
(Taylor & Francis, 2013-05-03)
The particle size of the primary particles is an important parameter influencing the drying behavior of droplets. In this work, the influence of particle size on the drying kinetics and grain properties was analyzed for ...
