Abstract
Dilatometric methods enable the measurement of variations of a dimension (length) of a sample, for example as a function of temperature. Volume changes of samples upon temperature changes can, therefore, be easily calculated. In the present setup (see section 2.1.1) the measurement of length variations as a function of pressure is also possible. According to (Equ. 04) and (Equ. 05), the slopes of the volume curves ΔV(p) (in an isothermal experiment) and ΔV(T) (in an isobaric experiment) are a direct measure for a sample’s isothermal compressibility κT and thermal expansion coefficient α, respectively.
