1.nounC2
Definition

the chemical or physical process in which a liquid mixture of tiny particles (called a sol) changes into a soft, jelly-like material (called a gel)

Example

The gelation of the dessert began moments after Yuki stirred in the gelatin powder.

everyday example: gelation of dessert with gelatin

Fatima watched the clear sol turn into a thick gel during gelation.

sol → gel transition observed in laboratory setting

Common collocations
  • gelation process
  • gelation point
  • gelation time
  • gelation temperature
  • thermal gelation
  • chemical gelation
  • speed up gelation
  • gelation of [substance]
Synonyms
  • gelling

    a less formal synonym; gelation is the standard technical noun

  • gelification

    a rarer technical synonym, mostly used in chemistry

  • solidification

    broader term — gelation produces a semi-solid, not a fully hard solid

Antonyms
  • liquefaction

    the process of turning a gel back into a liquid

  • melting

    the change from gel to liquid by heating

Usage Note

The primary modern sense of gelation. Widely used in chemistry, food science, cosmetics manufacturing, and materials engineering. The verb form is gel (or sometimes gelate). The opposite process — turning a gel back into a sol — is called liquefaction or melting.

Common Mistakes

Gelation is the same as freezing.
Gelation is the process of forming a gel, not freezing.
Sense 2 (freezing) is rare; sense 1 (gel formation) is the usual meaning in science.

2. the process by which a liquid becomes solid as a result of extreme cold

2.nounC2
Definition

the process by which a liquid becomes solid as a result of extreme cold

Example

The gelation of the pond happened overnight when the temperature fell to minus twelve degrees.

collocation: gelation of [water body] for freezing

Farmers checked whether gelation had occurred in their water pipes after three days of below-zero weather.

collocation: gelation of water pipes after freezing

Common collocations
  • gelation of [liquid/water body]
  • gelation point
  • gelation of pipes
Synonyms
  • freezing

    the everyday word for liquid becoming solid from cold; gelation is far rarer

  • solidification

    broader term covering any liquid-to-solid change, not just from cold

  • congelation

    a now-rare formal synonym for freezing, similar in register to gelation

Antonyms
  • melting

    the reverse process — solid turning back into liquid

  • thawing

    the warming of a frozen substance until it becomes liquid again

Usage Note

Rare in modern English for the freezing meaning; most speakers use freezing or solidification instead. You will most often find gelation in older scientific writing or in formal descriptions of cryogenic processes.

Common Mistakes

The gelation of the water happened at zero degrees.
The freezing of the water happened at zero degrees.
For everyday situations, use freezing instead of gelation.

Synonym discussion

Sense: noun/1

Gelation, gelling, solidification, and coagulation all describe a liquid becoming thicker or more solid, but they differ in process and result. Gelation is the specific technical term for a sol turning into a gel — a semi-solid network that traps liquid inside it, like jelly or soft contact lens material. Gelling is the less formal everyday word for the same process ('the jam is gelling nicely'). Solidification is much broader: it covers any liquid-to-solid change, whether by freezing (ice), hardening (concrete), or gelation (jelly). Coagulation is a separate process where particles clump together, often irreversibly, as when eggs cook or blood clots; the result is a solid mass rather than a soft gel. For everyday cooking, use setting or thickening instead of gelation. In a science report, gelation is the precise choice for sol-to-gel transitions.

Etymology

LatinEnglish

Gelation comes from the Latin noun gelātiō (freezing, a freezing), built from gelāre (to freeze, to congeal) plus -tiō (a suffix that turns a verb into a noun). The root gel- is related to Latin gelidus (icy cold) and English words like congeal, gelatin, and gelato. The word entered English in the 1600s with the meaning of 'freezing or solidifying by cold'. By the 1800s, as chemistry developed, the term was borrowed to describe the setting of gel-like substances — a meaning that has become its primary use today.
