Peptization vs. Coagulation — What's the Difference?

Peptization or deflocculation is the process of converting precipitate into colloid by shaking it with a suitable electrolyte called peptizing agent. This is particularly important in colloid chemistry or for precipitation reactions in an aqueous solution.

Coagulation, also known as clotting, is the process by which blood changes from a liquid to a gel, forming a blood clot. It potentially results in hemostasis, the cessation of blood loss from a damaged vessel, followed by repair.

To disperse (a precipitate) to form a colloid.

To cause transformation of (a liquid or sol, for example) into or as if into a soft, semisolid, or solid mass.

The stabilization of a hydrophobic colloidal sol by the addition of an electrolyte that is adsorbed on the particle surfaces

To become coagulated

The process of converting to a sol; bringing to a colloidal solution

The precipitation of suspended particles as they increase in size (by any of several physical or chemical processes)(e.g. of proteins)

The process by which blood forms solid clots.

Similar solidification of other materials (e.g. of tofu).

The change from a liquid to a thickened, curdlike, insoluble state, not by evaporation, but by some kind of chemical reaction; as, the spontaneous coagulation of freshly drawn blood; the coagulation of milk by rennet, or acid, and the coagulation of egg albumin by heat. Coagulation is generally the change of an albuminous body into an insoluble modification.

The substance or body formed by coagulation.

The process of forming semisolid lumps in a liquid
