Russian Translation(s) & Details for 'silica'

English Word: silica

Key Russian Translations:

• кремнезём [krʲɪm.lʲɪˈnʲe.zʲɵm] - [Formal, Scientific]
• диоксид кремния [dʲi.ɐkˈsʲid krʲɪmˈnʲi.jə] - [Formal, Technical, Used in precise chemical contexts]

Frequency: Medium (Common in scientific, geological, and industrial discussions but not in everyday conversation)

Difficulty: B2 (Intermediate; requires familiarity with scientific terminology and basic Russian noun declensions; for "диоксид кремния," it may be C1 due to compound word structure)

Pronunciation (Russian):

кремнезём: [krʲɪm.lʲɪˈnʲe.zʲɵm]

диоксид кремния: [dʲi.ɐkˈsʲid krʲɪmˈnʲi.jə]

Note on кремнезём: The stress falls on the third syllable ("zʲɵm"), which can be tricky for learners due to the soft consonants; pronounce with a clear "krʲ" at the start.

Audio: []

Meanings and Usage:

A hard, unreactive, colorless compound (SiO2) that occurs as the mineral quartz and as a principal constituent of sandstone and other rocks.

Translation(s) & Context:

• кремнезём - Used in formal scientific or geological contexts, such as describing minerals or materials in research.
• диоксид кремния - Preferred in chemical and industrial settings for emphasizing the molecular structure; often used in technical reports or manufacturing.

Usage Examples:

• Кремнезём является основным компонентом многих пород, таких как кварц.

  Silica is the main component of many rocks, such as quartz.

• В промышленности диоксид кремния используют для производства стекла и керамики.

  In industry, silica is used for producing glass and ceramics.

• Геологи изучают кремнезём в образцах из Сибири, чтобы понять древние процессы эрозии.

  Geologists study silica in samples from Siberia to understand ancient erosion processes.

• Диоксид кремния в чистом виде имеет высокую устойчивость к высоким температурам.

  Pure silica has high resistance to high temperatures.

• Кремнезём можно найти в повседневных материалах, таких как песок на пляже.

  Silica can be found in everyday materials, such as beach sand.

Russian Forms/Inflections:

"Кремнезём" is a masculine noun (3rd declension in Russian). It follows standard noun inflection patterns but has irregularities due to its compound structure. "Диоксид кремния" is a phrase where "диоксид" is masculine and "кремния" is genitive of "кремний" (a masculine noun).

For "кремнезём":

For "диоксид кремния," it remains relatively unchanged as a compound, but "кремния" inflects as the genitive form of "кремний." This phrase is invariant in most contexts.

Russian Synonyms/Antonyms:

• Synonyms: кварцевый песок (quartz sand, for a specific form), оксид кремния (oxide of silicon, less common variant)
• Synonyms: Note that "диоксид кремния" is often interchangeable with "кремнезём" in scientific texts, but "кремнезём" is more concise for general mineral references.
• Antonyms: органические соединения (organic compounds; implies non-mineral or synthetic materials)

Related Phrases:

• кремнезёмный песок - Sandy silica; refers to silica in granular form, commonly used in construction.
• диоксид кремния в нанотехнологиях - Silica dioxide in nanotechnology; highlights applications in modern tech.
• натуральный кремнезём - Natural silica; used in contexts discussing environmental or raw materials.

Usage Notes:

In Russian, "кремнезём" is the most direct equivalent to "silica" in geological contexts, while "диоксид кремния" is preferred in chemistry for its literal translation of the chemical formula (SiO2). Choose based on context: use "кремнезём" for broader mineral discussions and "диоксид кремния" for precise scientific writing. Both are formal and rarely used in casual speech. Grammatically, as masculine nouns, they require agreement in gender, number, and case with accompanying words (e.g., "этот кремнезём" for "this silica"). Avoid direct word-for-word translation from English, as Russian often emphasizes the compound nature.

• Scene restriction: Primarily in academic, industrial, or technical environments; not suitable for everyday conversation.
• Grammar note: In phrases, ensure proper genitive use, e.g., "содержание кремнезёма в породе" (content of silica in rock).

Common Errors:

English learners often confuse "кремнезём" with "кремний" (silicon), mistakenly using "кремний" for silica. Error example: Saying "Кремний в кварце" (meaning "Silicon in quartz") instead of the correct "Кремнезём в кварце" (Silica in quartz). Explanation: "Кремний" refers to the element silicon, not its oxide form. Correct usage: Always specify "кремнезём" for SiO2 compounds to avoid implying pure elemental silicon. Another error is incorrect declension, e.g., using nominative in all cases; remember to adjust for genitive in phrases like "производство из кремнезёма" (production from silica).

Cultural Notes:

In Russia, silica (кремнезём) holds significance in the country's vast geological resources, particularly in Siberia and the Ural Mountains, where it's mined for industrial use. This ties into Russia's history of mineral extraction, symbolizing national wealth in natural resources, and is often referenced in educational contexts to highlight environmental and economic themes.
