Bioactive glass coatings by suspension plasma spraying from glycoletherbased solvent feedstock
Elsevier (2017)Bioactive glasses are emerging as a substitute of hydroxyapatite in the development of bioactive coatings for biomedical applications. The deposition of these coatings is carried out by a wide range of methods, being ... -
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 ... -
Correlation between the wear resistance, and the scratch resistance, for nanocomposite coatings
Elsevier (2011)The nanoscratch test, used in this study, quantitatively characterizes the scratch behaviour of coatings. Some of the obtained parameters are plastic and elastic deformation, critical load to start the scratch, chipping ... -
Diffuse PM10emission factors associated with dust abatement technologies in the ceramic industry
Elsevier (2011-12)In this paper, an analytical methodology is proposed for estimating diffuse dust emissions from bulk solids managing (storage, handling, and transport) activities in the ceramic industry. The methodology is based on ... -
Effect of sodium addition on the preparation of hydroxyapatites and biphasic ceramics
(2008)HAP and biphasic ceramics of two different HAP and β-TCP proportions with substituted sodium were prepared through an aqueous precipitation method. The prepared powders were characterized by XRD, thermal analysis, FT-IR ... -
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 ... -
Microstructure and photocatalytic activity of suspension plasma sprayed TiO2 coatings on steel and glass substrates
Elsevier (2011-10-25)In this study, TiO2 coatings were deposited by suspension plasma spraying (SPS) from a commercial TiO2 nanoparticle suspension on two different substrates: a standard stainless steel and a Pyrex glass. Coatings were sprayed ... -
Nanostructured alumina from freeze-dried precursors
Wiley-Blackwell (2011)Nanocrystalline alumina has been obtained on the 100 g scale by thermal decomposition of precursors resulting from the freeze-drying of aqueous solutions of different aluminum-containing products, namely aluminum acetate ... -
Receptor models application to multi-year ambient PM10 measurements in an industrialized ceramic area: comparison of source apportionment results
Elsevier (2008-12)Ambient PM10 data collected in one of the largest industrialized ceramic areas of Europe were used to study similarities and differences in the source apportionment results from three widespread receptor models: chemical ... -
Relation between the scratch resistance and the chemical structure of organic-inorganic hybrid coatings
Elsevier (2011)Organic–inorganic hybrid materials can be defined as materials combining organic and inorganic domains in a nanometric scale. The development of these organic–inorganic hybrids has achieved properties from both organic and ... -
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 ...
