Determination of the wear resistance of traditional ceramic materials by means of micro-abrasion technique
(Elsevier, 2009)
Micro-abrasion techniques enable the surface wear of materials to be studied with greater precision than provided by other methods. In addition to their reliability, micro-abrasion techniques allow the wear phenomenon of ...
Quantifying road dust resuspension in urban environment by Multilinear Engine: A comparison with PMF2
(Elsevier, 2009)
Atmospheric PM pollution from traffic comprises not only direct emissions but also non-exhaust emissions because resuspension of road dust that can produce high human exposure to heavy metals, metalloids, and mineral matter. ...
Effect of slurry properties and operational conditions on the structure and properties of porcelain tile granules dried in an acoustic levitator
(Elsevier, 2012)
Spray-drying is a unit operation highly important in many industrial applications. In this work, the influence of the drying conditions on the final grain properties has been investigated in single droplet experiments.Porcelain ...
Foaming of flat glass cullet using Si3N4 and MnO2 powders
(Elsevier, 2009)
The introduction of a compound capable of releasing oxygen, such as MnO2, greatly improves the foaming ability of Si3N4 used as foaming agent in soda-lime glass powder, leading to expansion at a relatively low temperature ...
Study of the rheological behaviour of monomodal quartz particle beds under stress: a model for the shear yield functions of powders
(Elsevier, 2011-09-15)
A model is proposed that describes the yield locus of powders. The model is based on the adhesive contact of elastic spheres theory developed by Johnson, Kendall, and Roberts (JKR model). The proposed model improves the ...
Influence of composition on mechanical behaviour of porcelain tile. Part III: Effect of the cooling rate of the firing cycle
(Elsevier, 2011)
This paper is the third part of a study focusing on determining the influence of the porcelain tile composition on mechanical behaviour of sintered bodies. Tile compositions were prepared according to a simplex-centroid ...
Calcium carbonate thermal decomposition in white-body wall tile during firing. II. Influence of body thickness and calcite content
(Elsevier, 2012-05)
The thermal decomposition process of the calcium carbonate (calcite powder) contained in porous ceramic pieces, with the same composition as that used industrially to manufacture white-firing wall tile bodies, was studied ...
Hardness and Young's modulus distributions in atmospheric plasmas prayed WC–Co coatings using nanoindentation
(Elsevier, 2011-05-25)
A statistical indentation analysis of WC–Co coatings obtained by atmospheric plasma spray (APS) with two secondary plasma gases, H2 and He, was investigated using an instrumented indentation technique with the aim of ...
Solution Combustion Synthesis of (Co,Fe)Cr2O4 pigments
(Elsevier, 2012)
The synthesis of mixed cobalt–iron chromites, Fe1−ΨCoΨCr2O4 (0 ≤ Ψ ≤ 1), has been studied by Solution Combustion Synthesis using urea as fuel. Characterization by XRD and SEM showed that crystallinity, cell parameters, ...
Electrokinetic and rheological properties of highly concentrated kaolin dispersions: Influence of particle volume fraction and dispersant concentration
(Elsevier, 2010)
An industrial kaolin was selected and characterised. Different dispersions were prepared with solids volume fractions between φ{symbol} = 0.20 and φ{symbol} = 0.47 in the presence of sodium silicate (between X<sub>s</sub> ...
