Definition. Flocculation – process during which particles, for example, of a soil, dispersed in a solution contact and adhere each another, forming clusters, flocks, flakes, or clumps of a larger size. The term originates from the word “floc,” which is the flake of precipitate that comes out of solution.

Which is responsible for Deflocculation in soil?

Dispersion/Flocculation is a purely chemical phenomenon, driven by the balance of cations in the soil. Calcium has a very high flocculation power, while sodium and potassium cause dispersion.

What can I use as a Deflocculant?

Darvan 7 is typically preferred with porcelains and high iron content clay, while Darvan 811 can be used for stoneware, high fire slips and red low fire slips. Sodium silicate, also referred to as liquid glass, is another commonly used deflocculant in slip preparation.
