Precise material characterization for new materials, fundamental material properties, and scientific questions
Basic research provides the understanding on which new materials, technologies, and industrial applications are built. Whether it’s novel ceramics, alloys, polymers, semiconductors, composite materials or functional materials—their targeted development requires a precise understanding of their fundamental physical and thermal properties.
Thermal and thermophysical analytical methods enable the study of phase transitions, reaction mechanisms, thermal expansion, heat capacity, thermal conductivity , and thermal stability. Temperature-dependent changes can be characterized under defined atmospheric conditions and across a wide range of temperatures.
LINSEIS’s flexible analytical instruments can be used to investigate a wide variety of scientific questions—from the initial characterization of a new material to the experimental validation of models and theoretical material concepts.

FAQ – Basic Research
What material properties can be studied in basic research?
Thermal and thermophysical analytical methods can be used to determine, among other things, heat capacity, thermal conductivity, temperature conductivity, thermal expansion, phase transitions, and thermal stability. This allows for the comprehensive characterization of materials and the investigation of fundamental structure-property relationships.
What materials can be analyzed using LINSEIS systems?
The portfolio is suitable for a very wide range of materials—including metals and alloys, ceramics, polymers, glasses, semiconductors, composites, powders, porous materials, and functional materials. This makes it possible to investigate novel materials for which no established characterization methods yet exist.
Which measurement methods are particularly well-suited for basic research?
STA, DSC, TGA, DIL, and LFA are among the key methods used in thermal material characterization. Depending on the scientific question being addressed, they can be supplemented by techniques such as GSA, TMA, and electrical and thermoelectric measurement methods.
Why is it beneficial to combine different measurement methods?
A single measurement method usually captures only part of a material’s behavior. By combining, for example, STA, LFA, and DIL, it is possible to correlate thermal reactions, heat transport, and dimensional changes and gain a more comprehensive understanding of material mechanisms.
Can measurements be taken under different atmospheric conditions?
Depending on the measurement system, experiments can be conducted in inert, oxidizing, reducing, or other defined gas atmospheres. This makes it possible to investigate how environmental conditions affect reactions, stability, and material properties.
Why are temperature-dependent material properties important for scientific models?
Many material parameters are not constant but vary—sometimes significantly—with temperature. Experimentally determined temperature-dependent data therefore enhance the accuracy of simulations and enable a more realistic description of material behavior.
How does thermal analysis support the development of entirely new materials?
It provides quantitative information on phase stability, reaction behavior, heat transfer, and dimensional changes even in the early stages of research. This makes it possible to identify promising material concepts and then further develop them in a targeted manner toward a specific application.
