Linear thermal expansion of solids with a rod dilatometer

A dilatometer is used to determine the linear thermal expansion of a material as a function of temperature.

The temperature range of the measurement is generally between 25 °C and 1,600 °C. There is also an option to perform the test in a cryogenic atmosphere, which ranges from -175 °C to 300 °C. The typical heating rate is 3 °C/min.

As a result of the measurement, you will get the coefficient of thermal expansion (CTE) and the absolute change in sample length, both as a function of temperature. The testing can be performed in various atmospheres, including air, argon, CO₂, N₂, and O₂.
