Heating microscopy is a non-contact technique that, based upon an advanced image analysis of a specimen subjected to a thermal treatment reproducing industrial firing conditions, identifies several characteristic shapes and related temperatures key to the optimization of manufacturing processes in ceramics, metals, and alloys.
The characteristic temperatures the system can automatically identify include the beginning of sintering, softening, sphere, half-sphere, and melting/fusion. Morphometrix, the latest TA Instruments image analysis software, can also determine the following: flattening curve, contact angle curve, sample area variation curve, ratio curve between width and height, bloating effects, combustion, theoretical glass viscosity (V.F.T. equation) and surface tension (glasses) using the Young-Laplace equation.

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
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.
