Generally, the deformations of ceramic materials during and after firing may have a complex origin. If the products are made up of a single material, such deformations are mainly due to pyroplastic phenomena. In the case of glazed materials, two …
Generally, the deformations of ceramic materials after firing may have a complex origin. If the products are made up of a single material, such deformations are mainly due to pyroplastic phenomena. In the case of glazed materials, two further factors …
This report has been presented in the meeting called "High quality raw materials and their controls", which was held by Il sole 24 ore Business Media - Gruppo Editorial Faenza Editrice, Sassuolo, Auditorium Confindustra Ceramica, 22 february 2008. …
The glasses are intrinsically complex systems, quite difficult to study because their structure has no long range order and they are not in a thermodynamically stable state. Ceramic glazes are undoubtedly far more complex than glasses because in most …
The manufacturing of porous wall tiles is quite ancient but even with the newest technology still suffers of old problems. The study of the state of tension between glaze and body is fundamental in order to avoid some common defects, such as delayed …

The natural raw materials suitable for the production of ceramics consist of several families of minerals. Hydrated aluminosilicates, or clay minerals, are the most abundant in the surface portion of the earth’s crust and are fundamental components …
Some frequent glazing defects such as crazing are caused by an inadequate state of tension between the glaze and the ceramic body which is strongly related to various parameters. The most important are the coefficients of thermal expansion of glaze …
The technique of analysis proposed in this work for studying the sintering behaviour of some multilayer advanced ceramics is the optical non-contact dilatometry. In general, one of the most important aspects of the study of sintering is the shrinkage …
Thanks to the new double optical dilatometer, the ceramic scientist has the possibility to follow the behaviour of the sample during the heat treatment without interfering with the process. The applications brake the limits of traditional dilatometry …
