Mineralogy & Geochemistry Laboratories Thermal analysis Dilatometer

Dilatometer: Netzsch dilatometer: DIL 402 PC (Netzsch)

Dimensional changes in solids, melts, powders or pastes due to temperature changes can be determined using dilatometry. This is based on the physical principle of material expansion according to the equation dL/Lo = E-3 with an increase in temperature. The method was originally used for quality assurance of glass, ceramic and metal products, but it can also be applied to homogeneous rocks to obtain information on the solidification process.

  • Tube furnace with resistance winding Temperature range: 25°C to 1 400°C Integrated protection tube for gas flow
  • Temperature-dependent measurement of dimensional changes in solids -Quality control of glass, ceramics and metals
  • Detection of residual stresses caused by crystallisation
  • Behaviour of mineral and non-mineral solids through heating
