Densification of irregular polydispersed glass particles described as a complex relaxation process
José Luis, Amorós Albaro; Blasco Roca, Encarna; Feliu Mingarro, Carlos; Moreno Berto, Arnaldo Vicente Elsevier (2022)The sintering of compacts of irregular non-crystallising glass particles was studied by isothermal and constantrate heating experiments in a hot stage microscope. The resulting data fitted very well to kinetic equations developed ... -
Effect of kaolin addition on the sinter-crystallisation kinetics of compacts of a crystallising frit
José Luis, Amorós Albaro; Blasco Roca, Encarna; Feliu, C.; Moreno Berto, Arnaldo Vicente Elsevier (2022-08-22)Non-isothermal techniques were used to study the sintering and crystallisation kinetics of an anorthoclase- and diopside-devitrifying frit and mixtures of this frit with a commercial kaolin. Raising kaolin content was ... -
Effect of particle size distribution on the evolution of porous, microstructural, and dimensional characteristics during sinter-crystallisation of a glass-ceramic glaze
José Luis, Amorós Albaro; Blasco Roca, Encarna; Feliu Mingarro, Carlos; Moreno Berto, Arnaldo Vicente Elsevier (2021-08-05)Glass-ceramic test pieces, obtained from three different particle size distributions of a frit, were fired at temperatures between 800°C and 1200°C. Evolution of porous characteristics of the test pieces with firing ... -
Effect of particle size distribution on the sinter-crystallisation kinetics of a SiO2-Al2O3-CaO-MgO-SrO glass-ceramic glaze
José Luis, Amorós Albaro; Blasco Roca, Encarna; Moreno Berto, Arnaldo Vicente; Marín, N.; Feliu Mingarro, Carlos Elsevier (2020-05-20)Sinter-crystallisation kinetics of a glaze with an average particle size of 9.6µm, 4.0µm and 0.65µm, which devitrified anorthoclase and diopside, were studied by non-isothermal techniques. It was confirmed that the ... -
Improvement of the mechanical and aesthetic properties of a coating by inkjet technology
José Luis, Amorós Albaro; Blasco Roca, Encarna; Moreno Berto, Arnaldo Vicente; Feliu Mingarro, Carlos; Boschi, Anselmo O.; Marín, Natalia Wiley (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 ... -
Inkjet technology for ceramic products. Influence of some process variables on ink penetration
José Luis, Amorós Albaro; Moreno Berto, Arnaldo Vicente; Blasco Roca, Encarna; Pérez, Joaquín Javier; Navarro, Sandra; Reverter, Sandra Wiley (2019-07-27)Inkjet technology has become very popular in recent years and is nowadays widely used for decorating ceramic products. This has led to in-depth study of the operating principles and process variables involved. These ... -
Kinetics of the transformations occurring during the firing process of an industrial spray-dried porcelain stoneware body
José Luis, Amorós Albaro; Blasco Roca, Encarna; Moreno Berto, Arnaldo Vicente; Feliu Mingarro, Carlos Elsevier (2022-03-08)Pressed compacts of an industrial spray-dried porcelain stoneware powder, consisting mainly of albite, quartz, kaolinite, and illite, were thermally treated at different temperatures and times. Fired test piece bulk density ... -
Mechanical properties obtained by nanoindentation of sintered zircon-glass matrix composites
José Luis, Amorós Albaro; Blasco Roca, Encarna; Moreno Berto, Arnaldo Vicente; Feliu Mingarro, Carlos Elsevier (2020-01-10)This study was undertaken to determine the effect of zircon content and firing temperature on the hardness and indentation modulus of zircon–glass composites obtained by sintering. A standard non-devitrified borosilicate ... -
