Problems of deformation and crazing analysed through the new combined optical instruments

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 multi-layer products (glazed or …

Double beam optical dilatometry

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 …

New optical instruments for laboratory and process testing

Expert System Solutions has recently developed new no-contact and high temperature measurement techniques for the laboratory and for testing processes. The first results in this field were the automatic heating microscope, essential for studying the …

Optical Non-Contact dilatometry

The study of the behaviour and properties of ceramic materials during the heating process is one of the most critical steps in the development of innovative products in the fields of advanced and traditional ceramic materials. With the optical …

Understanding the behaviour of glazes-New Test possibilities

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 …
