Experimental study of deformations and state of tension in traditional ceramic materials

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 multi-layer materials …

The study of ceramic materials behaviour during firing

Traditional sintered ceramic bodies, like stoneware or porcelain-ware, undergo a viscous flow sintering process, where the driving force is mainly given by the surface tension of the liquid glassy phase, and the speed of the process is controlled by …

Effect of Quartz Particle Size on Porcelain Stoneware Sintering

The study of the behaviour and properties of ceramic materials during the heating process represents one of the most critical steps in the development of innovative products, both in the field of advanced and traditional ceramics.

Optical fleximeter to study the ceramic materials deformation

A new optical technique has been introduced to measure the state of tensions in glazed ceramic bodies, it has already been applied to the study of delayed crazing and pyroplastic deformation of ceramic body. The report explains how ceramic …

The measurement of Behaviour of Ceramic Materials during heat treatment

Delayed Crazing Resistence of Glazed Ceramic Materials

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 …

Effect of quartz and feldspar particle size on sintering behaviour

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. …

Crazing on porous wall tiles - A study using the Optical Fleximeter

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 …

Porous wall tiles putting crazing to the test

The manufacturing of porous wall tiles is quite ancient, but even with the newest technology it still suffers from old problems. The study of the state of tension between glaze and body is fundamental in order to avoid some common defects, such as …
