Dilatometry (DIL) & Thermomechanical Analysis (TMA)

Overview Group


Dilatometry (DIL) is the method of choice for highly precise measurement of dimension changes to solids, melts, powders and pastes at a programmed temperature change and with negligible sample strain (e.g. ASTM E831, ASTM D696).

Information from DIL measurements:

  • Linear thermal expansion
  • Coefficient of thermal expansion (CTE)
  • Volumetric expansion
  • Shrinkage steps
  • Softening point
  • Glass transition temperature
  • Phase transitions
  • Sintering temperature and step
  • Density change
  •  Influence of additives and raw materials
  • Decomposition temperature of e.g., organic binders
  • Anisotropic behavior
  • Optimization of firing process
  • Caloric effects by using c-DTA®
