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 ... -
Characterizing Breakthrough Cancer Pain Using Ecological Momentary Assessment with a Smartphone App: Feasibility and Clinical Findings
villegas, Francisco; Martínez-Borba, Verónica; Suso-Ribera, Carlos; Castilla, Diana; Zaragoza, Irene; García-Palacios, Azucena; Ferrer, Carlos MDPI (2021-06-03)Background: mobile applications (apps) facilitate cancer pain ecological momentary assessment (EMA) and provide more reliable data than retrospective monitoring. The aims of this study are (a) to describe the status of ... -
Fracture patterns of quartz particles in glass feldspar matrix
Gilabert Villegas, Francisco A.; Dal Bó, Marcelo; Cantavella Soler, Vicente; Sánchez-Vilches, Enrique Elsevier (2012)We report a comparison between experimental evidences and simulation results of the micro cracking in ceramic materials provoked by the cooling process. The solid model and the fracture process are carried out using the ... -
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 ... -
Modeling microstructural damage of silicate-based ceramics and its influence on macroscopic fracture strength
Gilabert Villegas, Francisco A.; Cantavella Soler, Vicente; Dal Bó, Marcelo; Sánchez-Vilches, Enrique 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 ... -
Relationship between Young's modulus and temperature in porcelain tiles
De Oliveira, Antonio Pedro Novaes; Sánchez-Vilches, Enrique; Cantavella Soler, Vicente; Gilabert Villegas, Francisco A. Elsevier (2012)A focused research was conducted on samples prepared from an industrial porcelain tile composition containing quartz, used to produce ceramic floor tiles, with the aim of evaluating the variation of fired specimens’ Young's ...
