A new possibility for measurements of glass transition point, fictive temperature and activation energy of viscous flow in the glass transition range is shown by using a contactless horizontal optical dilatometer and pressed powder samples. The …
In this paper, the effects of grains morphology on sintering behaviour and final microstructure of a porcelain tile body were studied by means of optical dilatometry, heating microscopy and SEM investigations. Two samples made up of the same …
The optical measurement of thermo-mechanical properties allows the sample to be completely free from constraints. This enables the possibility to measure the true change in size or volume of a material during a sintering process. Thanks to the fact …
