General Information


(Thermal expansion) Dilatometer


Room 34J-0-350

Key words:

thermal analysis of solids, thermal expansion, Dilatometry

Measured quantity:

In dilatometry, the dimension of a substance under negligible load is measured as a function of temperature while the substance is subjected to a controlled temperature program. Examples of applications are thermal expansion measurements, softening point determinations. Different gas atmospheres are possible.

Main application:

Dilatometry is a thermal analysis technique that measures the length of solid samples as a function of temperature. The specimen is placed in the head assembly and is heated in a controlled manner. Changes in the dimensions of the specimen are transmitted via an alumina thrust rod and detected by an electrical transducer. The push rod and the sample holder will also undergo dimensional changes during measurement so corrections and calibrations must be made. Applications of dilatometry include measurement of the coefficient of thermal expansion, detection of phase changes, sintering studies and determination of glass transition and softening temperatures.
