1
formation of crystals
when a substance becomes solid crystals
Модел на употреба:
crystallisation of [substance] (from [solution/melt])
Честа грешка:
Learners often misspell it as *crystalisation* (one 'l'), or mix it up with the US spelling *crystallization*.
Синоними
crystal formation (A plain-language paraphrase of the process.)
|
solidification (Broader term; not necessarily into a crystal structure.)
|
precipitation (Often used when a solid forms from a solution, but not always as crystals.)
Антоними
dissolution (Crystals or solids go into solution instead of forming.)
|
melting (A solid becomes liquid rather than forming crystals.)
Колокации

|initiate crystallisation
|trigger crystallisation

Примери
- As the solution cooled, crystallisation began along the sides of the beaker.
- Rapid crystallisation can trap impurities inside the crystal lattice.
- The lab monitored the crystallisation of salt as the water evaporated.
Примери за учащи

purifying by forming crystals
a way to clean a substance by making crystals
Модел на употреба:
crystallisation of [compound] (to remove [impurities])
Честа грешка:
Learners may use *crystallisation* when they specifically mean *recrystallisation* (crystallising again for extra purification).
Синоними
crystal purification (Emphasises the goal (purity) rather than the physical process.)
|
separation (Much broader; crystallisation is one specific separation technique.)
Антоними
contamination (The opposite outcome: introducing impurities rather than removing them.)

Примери

3
becoming clear and definite
when ideas become clear and fixed
Модел на употреба:
the crystallisation of [idea/plan/opinion]
Честа грешка:
Learners may overuse it in casual speech; this figurative sense is more common in formal writing than in everyday conversation.
Синоними
clarification (Focuses on becoming easier to understand, not necessarily becoming fixed.)
|
solidification (Metaphor for becoming firm; less about mental clarity.)
|
taking shape (More informal and less 'fixed' than crystallisation.)
Антоними
confusion (Lack of clarity and definite form.)
|
vagueness (Not clearly defined or settled.)

crystal deposit or mass
a layer or mass of crystals
Модел на употреба:
a crystallisation of [substance] (on/in [place])
Честа грешка:
This countable use (*a crystallisation*) is less common; learners may prefer 'crystals' or 'crystal deposit' in general writing.
Синоними
crystal deposit (More transparent and common outside specialist writing.)
|
encrustation (Emphasises a crust on a surface; may not be strictly crystalline.)
Антоними
solution (Material is dissolved rather than present as crystals.)
