Microstructural analyses

These are for describing the microstructure of ceramic materials; characterizing their morphology by defining the distribution, the shape and the size of the grains (or particles) and the pores. A real investigative tool,these may be run at any stage of the manufacturing process, as much for a raw material in powder form as for a part of a finished or semi-finished product to carry out intermediary tests.

microstructurales

They allow for:

  • the uncovering of any potential inconsistencies
  • defect analysis
  • the running of a local basic chemical analysis

They are run by:

  • scanning microscope, SEM, coupled with an electron probe microanalyser, EPMA, to determine themicrostructure and local basic chemical analysis.
  • mercury intrusion porosimeter to determine the open porosity and the pore size distribution
  • X-ray diffractometer to characterize the crystalline structure (calculation and dosing of existingcrystalline phases, the size of nanometric crystallites, measuring crystal structure parameters…)
  • A very high resolution digital microscope (3D observation and dimensional control)
