Elemental ID for Ceramic Materials
Elemental analysis using EDS with scanning electron microscopy (SEM) provides material information correlated to structure for ceramic materials. Processes can be evaluated to optimize the best composition for desired mechanical properties and product performance.
EDS can be done at a point, across a line or over an area. This data can be used in ceramic research and development to chart nanoparticle diffusion through a porous ceramic, to identify second phases on ceramic surfaces or to analyze agglomerates or contamination.
An EDS map can correlate phase morphology to composition for ceramic materials. An example of this is shown below. Image and data courtesy of CoorsTek:
