1. The measurement of changes in the volume or dimensions of a material as a function of temperature or other variables.
Usage: technical; used in materials science and physics

Examples

• Dilatometry is used to study how metals expand when heated.
• The engineer performed dilatometry on the ceramic sample to determine its thermal expansion coefficient.
• Dilatometry data helped researchers understand the phase transitions in the polymer.
• Using dilatometry, scientists measured the volume change of the alloy during cooling.
• The laboratory equipped itself with a dilatometer to conduct precise dilatometry experiments.
