formation of crystals

when a substance becomes solid crystals

תבנית שימוש: crystallisation of [substance] (from [solution/melt])
טעות נפוצה:
Learners often misspell it as *crystalisation* (one 'l'), or mix it up with the US spelling *crystallization*.
מילים נרדפות
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.)
הפכים
dissolution (Crystals or solids go into solution instead of forming.) | melting (A solid becomes liquid rather than forming crystals.)
צירופים
crystallisation occurs |initiate crystallisation |trigger crystallisation |crystallisation from solution |crystallisation of sugar |salt crystallisation |ice crystallisation |crystallisation rate |crystallisation temperature |controlled crystallisation
נושאים
science |chemistry |materials
דוגמאות
  • 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.
דוגמאות ללומדים
  • Crystallisation happens when crystals form.
  • We waited for crystallisation in the solution.

purifying by forming crystals

a way to clean a substance by making crystals

תבנית שימוש: crystallisation of [compound] (to remove [impurities])
טעות נפוצה:
Learners may use *crystallisation* when they specifically mean *recrystallisation* (crystallising again for extra purification).
מילים נרדפות
crystal purification (Emphasises the goal (purity) rather than the physical process.) | separation (Much broader; crystallisation is one specific separation technique.)
הפכים
contamination (The opposite outcome: introducing impurities rather than removing them.)
צירופים
purification by crystallisation |crystallisation step |industrial crystallisation |crystallisation unit |crystallisation process |batch crystallisation |continuous crystallisation |crystallisation for purification |recover by crystallisation |high-purity crystals
נושאים
science |chemistry |manufacturing
דוגמאות
  • The final crystallisation removed most of the coloured impurities from the product.
  • Crystallisation is used in industry to recover sugar from syrup.
  • They added a seed crystal to make the crystallisation more predictable.
דוגמאות ללומדים
  • Crystallisation can help purify a chemical.

becoming clear and definite

when ideas become clear and fixed

תבנית שימוש: the crystallisation of [idea/plan/opinion]
טעות נפוצה:
Learners may overuse it in casual speech; this figurative sense is more common in formal writing than in everyday conversation.
מילים נרדפות
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.)
הפכים
confusion (Lack of clarity and definite form.) | vagueness (Not clearly defined or settled.)
צירופים
the crystallisation of ideas |the crystallisation of a plan |the crystallisation of views |a moment of crystallisation |lead to crystallisation |help the crystallisation of |crystallisation into a policy |crystallisation of tensions |crystallisation of identity |crystallisation of opposition
נושאים
thinking |writing |emotions
דוגמאות
  • The workshop led to the crystallisation of a workable strategy.
  • A few tough questions prompted the crystallisation of her argument.
  • The crisis accelerated the crystallisation of public opinion.
דוגמאות ללומדים
  • The meeting helped the crystallisation of our plan.

crystal deposit or mass

a layer or mass of crystals

תבנית שימוש: a crystallisation of [substance] (on/in [place])
טעות נפוצה:
This countable use (*a crystallisation*) is less common; learners may prefer 'crystals' or 'crystal deposit' in general writing.
מילים נרדפות
crystal deposit (More transparent and common outside specialist writing.) | encrustation (Emphasises a crust on a surface; may not be strictly crystalline.)
הפכים
solution (Material is dissolved rather than present as crystals.)
צירופים
a crystallisation forms |surface crystallisation |a white crystallisation |salt crystallisation on |crystallisation deposit |crystallisation layer |needle-like crystallisation |a heavy crystallisation |visible crystallisation |patches of crystallisation
נושאים
science |chemistry |materials
דוגמאות
  • A white crystallisation appeared around the rim after the liquid dried.
  • The technician scraped off the crystallisation to weigh the product.
  • You can see crystallisation on the surface where the brine seeped out.
דוגמאות ללומדים
