barium carbonate
C1/C2Technical/Scientific
Definition
Meaning
A white, insoluble powder with the chemical formula BaCO₃.
A compound used primarily in the ceramics, glass, and brick industries, and as a rodenticide. Also historically used in the production of optical glass and as a precursor for other barium compounds.
Linguistics
Semantic Notes
This is a specific chemical compound term. Its meaning is fixed and precise, with little semantic drift. It is a hyponym of 'carbonate' and 'barium compound'.
Dialectal Variation
British vs American Usage
Differences
No significant lexical or semantic differences. Potential minor spelling variations in related technical documents (e.g., 'colourant' vs. 'colorant' in associated descriptions).
Connotations
Neutral technical term in both varieties. Connotations are purely related to its industrial, chemical, or toxicological applications.
Frequency
Equally low-frequency and specialized in both dialects, appearing almost exclusively in scientific, industrial, or regulatory contexts.

Usage
Context Usage
Business
Discussed in supply chain, material safety data sheets (MSDS), and procurement for manufacturing industries.
Academic
Used in chemistry, materials science, and geology textbooks and research papers on synthesis, decomposition, or applications.
Everyday
Virtually never used. If encountered, likely in the context of pest control (rat poison) warnings or specialised hobbies like pottery glazing.
Technical
The primary register. Used in formulations, chemical process descriptions, hazard labelling, and industrial specifications.
Examples
By Part of Speech
verb
British English
- The mixture was then carbonated to form the barium salt.

Examples
By CEFR Level
- Barium carbonate is a chemical.
- Barium carbonate is a white powder used in some industries.
- This poison contains barium carbonate.
- The insolubility of barium carbonate makes it useful in certain chemical separations.
- Manufacturers add barium carbonate to clay to improve the quality of bricks.
- Upon thermal decomposition, barium carbonate yields barium oxide and carbon dioxide, a reaction exploited in industrial processes.

Learning
Memory Aids
Mnemonic
Think: 'BA' (chemical symbol) + 'RI' (rhymes with 'rye') + 'UM' makes 'BARIUM'. It's a CARBONATE, so it contains carbon and oxygen (CO₃). Together: 'Barium Carbonate' = BaCO₃.
Conceptual Metaphor
N/A for this precise technical term. In very broad educational contexts, it might be metaphorically described as a 'building block' or 'ingredient' in manufacturing.
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with 'барий' (barium, the element) – 'barium carbonate' is 'карбонат бария'.
- Ensure the translation specifies 'карбонат', not other barium salts like 'сульфат' (sulfate) or 'нитрат' (nitrate).
Common Mistakes
- Misspelling as 'baryum carbonate' (French influence).
- Incorrect pronunciation stress: /ˈbærɪəm/ instead of /ˈbɛːriəm/ or /ˈberiəm/.
- Confusing its properties (insoluble) with those of barium sulfate.

FAQ
Frequently Asked Questions
Yes. It is toxic if ingested, as it dissolves in stomach acid to form soluble, poisonous barium ions. It requires careful handling.
Its main uses are in the ceramics industry (for glazes and bricks), in glassmaking, and historically as a rodenticide. It is also a starting material for making other barium chemicals.
It is typically a fine, odourless, white powder or crystalline solid.
No, it is practically insoluble in pure water. However, it reacts with and dissolves in acids.
