An estimate of quartz content and particle size in porcelain tiles from young's modulus measurements
Dal Bó, Marcelo; Cantavella Soler, Vicente; Sánchez-Vilches, Enrique; Gilabert Villegas, Francisco A.; Boschi, Anselmo O.; Hotza, Dachamir Elsevier (2017)The influence of quartz particle size, weight content and firing temperature on the Young's modulus of porcelain tiles was studied. To simulate a porcelain tile microstructure, an albite glass matrix with added crystalline ... -
Analysis of the development of microscopic residual stresses on quartz particles in porcelain tile
De Noni, Agenor; Hotza, Dachamir; Cantavella Soler, Vicente; Sánchez-Vilches, Enrique Elsevier (2008-10)This paper examines the development of microscopic residual stresses on quartz particles in porcelain tile using the XRD technique. The study was conducted with a typical porcelain tile composition consisting of sodium ... -
Effect of quartz particle size on the mechanical behaviour of porcelain tile subjected to different cooling rates
De Noni, Agenor; Hotza, Dachamir; Cantavella Soler, Vicente; Sánchez-Vilches, Enrique Elsevier (2009-04)Porcelain tile is a high-performance ceramic tile, in which quartz is a major compositional component. After the firing cycle, macroscopic residual stresses develop in the product as a result of rapid cooling. Further, ... -
Fracture toughness and temperature dependence of Young's modulus of a sintered albite glass
Dal Bó, Marcelo; Cantavella Soler, Vicente; Sánchez-Vilches, Enrique; Hotza, Dachamir; Gilabert Villegas, Francisco A. Elsevier (2013-03)Albite glass is an important component in many ceramic compositions, often used as liquid phase during the sintering process. Nevertheless, in spite of its almost ubiquous presence in the final microstructure of these ... -
Influence of composition on mechanical behaviour of porcelain tile. Part I: microstructural characterization and developed phases after firing
De Noni, Agenor; Hotza, Dachamir; Cantavella Soler, Vicente; Sánchez-Vilches, Enrique Elsevier (2010-03)The porcelain tile is a ceramic product with high technical and aesthetic performance, whose composition is formulated from a mixture of clay or kaolin, quartz and feldspar. This paper is the first part of a study focusing ... -
Influence of composition on mechanical behaviour of porcelain tile. Part II: mechanical properties and microscopic residual stress
De Noni, Agenor; Hotza, Dachamir; Cantavella Soler, Vicente; Sánchez-Vilches, Enrique 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 ... -
Influence of composition on mechanical behaviour of porcelain tile. Part III: Effect of the cooling rate of the firing cycle
De Noni, Agenor; Hotza, Dachamir; Cantavella Soler, Vicente; Sánchez-Vilches, Enrique 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 ... -
Influence of macroscopic residual stresses on the mechanical behavior and microstructure of porcelain tile
De Noni, Agenor; Hotza, Dachamir; Cantavella Soler, Vicente; Sánchez-Vilches, Enrique Elsevier (2008-09)The development of macroscopic residual stress, as in glass-tempering processes, was studied for porcelain tile. Mechanical strength was observed to increase less than might be theoretically expected, owing to deterioration ... -
Modelización mecánica del enfriamiento rápido en sistemas tipo gres porcelánico
Dal Bó, Marcelo; Cantavella Soler, Vicente; Sánchez-Vilches, Enrique; Hotza, Dachamir; Boschi, A. O. Sociedad Española de Cerámica y Vidrio (2012-03)This paper analyses the effect of cooling on mechanical behaviour, in particular, on the residual stresses that appear when materials of the porcelain tile type are involved. However, these compositions have a very complex ... -
Modelling the Influence of Manufacturing Process Variables on Dimensional Changes of Porcelain Tiles
Santos Barbosa, Dolly; Boix, Juan; Hotza, Dachamir; Mallol Gasch, Gustavo Hindawi (2013-09)A model to study the influence of main process variables (powder moisture, maximum compaction pressure, and maximum firing temperature) on the intermediate variables (mass, dry bulk density, size, and thickness) and the ...
