Mechanical, Thermomechanical and Rheological Analyses (MTRA)

The MTRA platform characterises mechanical performances (elasticity, rigidity, damping …) and determines the thermal properties of all types of materials.

Description

Areas of activity :

The activities of the platform focus on the structural characterisation of all types of solid materials by X-ray diffraction or diffusion : identification of phases, study of crystallinity or organisation, reflectometry, grazing incidence, structural determination on powder, observation of phase transitions in temperature and controlled atmosphere. In addition, these characterisations can be supplemented by X-ray Fluorescence spectrometry analyses which make it possible to determine the chemical composition of a sample and thus facilitate structural identification.

Main equipment (strengths of the Institute) :

The platform has 3 diffractometers, one thermodiffractometer, one SAXS-WAXS and an X-ray fluorescence spectrometer :

  • 3 powder diffractometers : 2 in reflection geometry with autosampler (Bruker D8 ADVANCE and PANalytical, X’Pert PRO MPD) and 1 in transmission geometry (STOE Stadi-P and Bruker D8 ADVANCE)
  • 1 thermodiffractometer (PANalytical, X’Pert PRO MPD) equipped with a temperature chamber (Anton Paar HTK1200)
  • 1 x SAXS-WAXS small angle X-ray diffusion unit (Rigaku SMax 3000)
  • 1 Wavelength Dispersion X-Ray Fluorescence Spectrometer (PANalytical, Zetium)
