Characterization of nanostructured ceramic and cermet coatings deposited by plasma spraying
(Wiley-Blackwell, 2011)
Industry has a growing need of advanced coatings for a variety of applications (aerospace, special machinery, medicine ...). Nanostructured coatings have the potential of providing novel materials with enhanced properties. ...
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 ...
A new cleaner process to prepare pressing-powder
(Sociedad Española de Cerámica y Vidrio, 2011)
An alternative cleaner process of pressing-powder preparation, based on filter-pressing and a novel granulation method, is presented to substitute the existing spray-drying process. In the new process, about two-thirds of ...
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 ...
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 ...
Desenvolvimento de vidrados cerâmicos com propriedades bactericidas e fungicidas
(Associação Brasileira de Cerâmica, 2011-05)
Nos últimos anos foram desenvolvidas técnicas que permitem a síntese de materiais que, ao menos
em uma de suas dimensões, são de tamanho nanométrico (1 a 100 nm), apresentando assim propriedades e
funções significativamente ...
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. ...
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 ...
Influence of composition on mechanical behaviour of porcelain tile. Part II: mechanical properties and microscopic residual stress
(Elsevier, 2010-03)
The influence of the starting composition on the mechanical properties of sintered porcelain tile was evaluated based on the linear elastic fracture mechanics. Tile compositions were prepared according to a simplex-centroid ...
New model to tune the dielectric properties of dense and half-dense sintered polycrystalline cu-doped Ni–Zn ferrite
(ElsevierEuropean Ceramic Society, 2021-11-30)
Sintered polycrystalline Cu-doped Ni–Zn ferrite specimens have been successfully prepared by a conventional ceramic method using different pressure-temperature-time cycles. The studied samples, with an average grain size ...
