Thermo-dilatometric analysis

Mechanical analysis (Nano to Micro/Macro)

Dilatometry is a thermoanalytical technique used to measure the length of samples, under negligible constant load when subjected to a controlled temperature/time program.

It is widely used to perform different types of analyses:

  • Thermal expansion (α = Coefficient of thermal expansion, CTE))
  • Dimensional stability of the samples;
  • Shrinkage/densification;

 

The available equipment is a Dual and Differential Dilatometer, with a double sample arrangement (two high-resolution inductive displacement transducers for the simultaneous analysis of two samples), motorized independent movement of both the two pushrods, automatic zero positioning of the pushrods and control of theirs contact force, vacuum-tight design, possibility to perform the analyses in static air or using flowing gas (air, N2, Ar, CO2).

The analyses are performed following the GLP (Good Laboratory Practice) principles. The maximum working temperature is 1600°C, depending on material and analysis conditions used.
