TMA is a technique that uses a non-oscillatory stress, such as compression, tension, or bending, to measure changes in the form of a sample while it is heated or cooled. Based on the sample shape and measurement objective, the TMA method provides measurement modes such as compression loading, tensile loading, penetration loading, and 3-point bending. TMA is commonly used to determine a sample’s thermal expansion ratio and softening temperature.

The TMA from Rigaku uses the differential expansion concept, which cancels out any thermal expansion or shrinkage caused by the detecting device. The load control can be configured to two modes in addition to constant load: constant rate loading mode and sine-wave cyclic loading mode.

Sample controlled TMA (SCTMA), in which the temperature is regulated by the shrinkage rate, can be installed as an option for simulating sintering in ceramics and producing sintered materials with suppressed grain growth.
