HM 867 Heating Microscope

The Optical Dilatometry Platform HM 867 is a stand-alone Heating Microscope that is a standard instrument for process optimization in the ceramics industry. A single camera on the optical bench frames the entire sample and records the sequence of the characteristic shape changes and the temperature throughout the experiment.

Key Features

High-temperature capability: The HM 867 can reach temperatures up to 800°C, which allows for the observation of sample behavior at high temperatures.
In-situ observation: The microscope allows for the observation of the sample during heating, providing real-time information on changes in the sample's physical and chemical properties.
High-resolution imaging: The microscope is equipped with high-quality optics and a high-resolution camera, which allows for the observation of fine sample details and changes.
Automatic image analysis: The HM 867 comes with advanced software that enables automatic image analysis, making it easy to track changes in the sample properties over time.
Multiple observation modes: The microscope can be used in different observation modes, including transmitted light, polarized light, and reflected light, providing a range of options for material characterization.

ODP 868 Optical Dilatometry Platform

Result of over twenty years of R&D of optical instruments for the study of the thermo-mechanical behavior of materials, ODP 868 makes possible the analysis of samples beyond the limits of classical heating microscopy. Its versatility makes of ODP 868 the most innovative tool for production and R&D laboratories for the optimization of all the industrial processes that involve thermal cycles.

The Heating Microscope mode uses a 5Mpix high resolution camera to study the physical behavior of the materials during the industrial firing cycles.

Key Features

Analyze bending caused by the difference in thermal expansion between coupled materials (i.e.: body and a glaze)
Determine coupling temperature (formerly done with a Steger tensiometer);
measure bending caused by the difference in sintering behaviour between several coupling materials (i.e.: glaze, engobe and ceramic body)
Measure bending during cooling, caused by the volume variation of the glassy phases
Study pyroplastic deformation and speed of deformation occurring in the material at high temperature due to its weight;
