Ceramics, Cermets & Composites
Determine phase diagrams, thermal stability. Measure data for heat transfer simulation in ceramics based systems. Understand powders sintering.
Most ceramics producers and users want to keep control of their structure and reactivity. Preventing ceramic parts from thermal or mechanical ageing is also key.
-
Phase diagram
Improvement of ceramics properties may come from a better control over their structure. You can benefit from phase diagrams for such a control. DTA or DSC directly measure characteristic temperatures of a phase diagram. Drop calorimetry, together with modelling, is an alternative indirect method.
-
Sintering
You can make some ceramics parts like those manufactured by 3D printing or injection molding using powder sintering. During sintering, the dimensions of the part changes. You can use TMA to measure powder expansion, shrinkage, and the final part’s density.
-
Thermophysical properties
Ceramics’ Coefficient of thermal expansion (CTE) and heat capacity (Cp) are important technical specifications. It is especially true for heat transfer and mechanical stress simulation. You can use TMA and calorimetry to accurately measure these parameters.
-
Heat of Formation
Interested in the long term stability of complex ceramics? You can benefit from thermodynamics measurement. Heat of formation, measured by drop calorimetry, helps at predicting the ceramics’ reactivity. It is also used for phase diagrams calculation.
-
Oxygen ratio, stoichiometry
The properties of oxides like ceramics depend on their oxygen content. You can check the stoichiometry or oxygen to metal ratio of your ceramics using TGA.
