Powder Processing - an overview ScienceDirect Topics

Powder processing is the most commonly used technique for producing ceramic nanocomposites. As discussed in previous sections, this technique resulted in very good dispersions of nanoparticles in the ceramic matrix although not so good results were obtained for CNTs due to the complex processing steps required for de-agglomeration of CNTs.
