These are used to characterize physical and chemical properties of ceramic materials.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.
They allow for :
- confirmation that a raw material is suitable for the project,
- adjustments in the manufacturing process
- product testing during and at the end of the production process.
They are run by :
- a dry or liquid state granulometry laser to test the distribution and size of particles in a powder,
- a specific BET surface and powder mesoporosity analyzer,
- TPR/TPO/TPD chimisorption apparatus for catalyst analysis
- a helium pycnometer to determine the actual density of a powder or solid
- a rheometer to determine flow behavior in suspensions or in ceramic pastes (viscosity, stressthreshold, yield value and thixotropic behavior measurements…)
- An FTIR spectrometer for identifying compounds and determining the composition of a solid or liquid sample
- an optical tensiometer for measuring surface tension and contact angles of a liquid on a substrate
