Modeling microstructural damage of silicate-based ceramics and its influence on macroscopic fracture strength
(Elsevier, 2014-05-15)
The aim of this work is to clarify the influence of quartz inclusions added to a vitreous matrix on the macroscopic fracture toughness (KICKIC). We use numerical simulations to model a silicate-based ceramic material as a ...
Evaluation of texture distribution during the industrial polishing process of porcelain stoneware tiles
(Elsevier, 2013)
The present work addresses the distribution of texture over the surface of porcelain stoneware tiles due to kinematics imposed by industrial polishing process. The scratching process was simulated using a computational ...
Synthesis and electrochemical behavior of ceramic cation-exchange membranes based on zirconium phosphate
(Elsevier, 2013-05)
Cation-exchange membranes made exclusively from ceramic materials have been synthesized by means of the impregnation of microporous ceramic supports with zirconium phosphate. Changes in the pore size distribution and total ...
Kinetic model of the dissolution process of a zirconium white frit. Influence of the temperature
(Elsevier, 2015)
The dissolution of a zirconium white frit has been studied in order to know the kinetics of the process. The concentrations of five cations (Ca, Mg, Zn, Si and B) have been determined by ICP-OES after carrying out the ...
Effect of average grain size and sintered relative density on the imaginary part – µ″ of the complex magnetic permeability of (Cu0.12Ni0.23Zn0.65)Fe2O4 system
(Elsevier, 2016)
The influence of the sintered microstructure on the electromagnetic properties of Cu-doped NiZn ferrites were investigated. Two of the main variables of the thermal cycle have been modified: the maximum sintering temperature ...
Electrophoretic deposition of ZnO/alginate and ZnO-bioactive glass/alginate composite coatings for antimicrobial applications
(Elsevier, 2015)
Two organic/inorganic composite coatings based on alginate, as organic matrix, and zinc oxide nanoparticles (n-ZnO) with and without bioactive glass (BG), as inorganic components, intended for biomedical applications, were ...
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 ...
