Thermal expansion

The thermal behavior of samples strongly depends on the coefficient of expansion or coefficient of thermal expansion. The thermal behavior between room temperature and up to 2000°C can be investigated using the dilatometers available in the working group. Both rectangular and cylindrical samples can be measured.

Linseis L75

The Linseis L75 dilatometer enables measurements of the thermal expansion in the range from room temperature to a maximum temperature of 1400°C under normal ambient atmosphere.
