freeze gelation (rus. золь-гель переход, стимулированный замораживанием otherwise freeze thawing) — concentration-induced phase transition, transformation of a sol into a gel caused by sol cooling below the crystallisation temperature of the solvent.

Description

The solvent crystal formation leads to the displacement of the remaining liquid into the space between the crystals with a simultaneous increase in the sol concentration, which stimulates its transition into the gel state.
