peptization

With many precipitates, peptization occurs during washing.

Flocculation is the process inverse of peptization.

Peptization is also used in nanoparticle synthesis to make a large grouping of particles split into many primary particles.

Stabilization (peptization)

Peptization can be reduced with careful technique and washing with a solution of appropriate pH and ionic strength.

In the synthesis of titania (titanium dioxide) nanoparticles, peptization involves adsorption of quaternary ammonium cation on the titania surface.

The reverse process whereby particle aggregates are disrupted and dispersed as individual particles is referred to as peptization hardly occurs spontaneously, but may occur under stirring or shear.
