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 ...
Modelling the Influence of Manufacturing Process Variables on Dimensional Changes of Porcelain Tiles
(Hindawi, 2013-09)
A model to study the influence of main process variables (powder moisture, maximum compaction pressure, and maximum firing temperature) on the intermediate variables (mass, dry bulk density, size, and thickness) and the ...
Atmospheric plasma spraying coatings from alumina–titania feedstock comprising bimodal particle size distributions
(Copyright © Elsevier, 2013)
In this work, Al2O3–13 wt% TiO2 submicron-nanostructured powders were deposited using atmospheric plasma spraying. The feedstocks were obtained by spray drying two starting suspensions of different solids content, prepared ...
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 ...
Kinetic study of the thermal decomposition process of calcite particles in air and CO2 atmosphere
(Elsevier, 2013-05)
The thermal decomposition process of calcite particles (0.45–3.60 mm average diameter), made up of porous agglomerates of very small CaCO3 microcrystals, was studied in the 975–1216 K temperature range. The experiments ...
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 ...
Effect of feedstock and plasma gun on the microstructure and bioactivity of plasma sprayed bioactive glass coatings
(Elsevier, 2021-01-25)
Plasma–sprayed 45S5 bioactive glass coatings were manufactured using two types of powder
feedstocks (commercial and lab–made 45S5 glass) and two plasma torches (single and triple
cathode) to analyse their influence on ...
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 ...
