tantalate
C1Technical / Scientific
Definition
Meaning
A salt or ester of tantalic acid, containing the anion TaO₃⁻ or related anions.
In materials science and chemistry, any compound derived from tantalum oxide, often used in the context of specific crystalline structures like lithium tantalate for optoelectronic applications.

Examples
By CEFR Level
- Lithium tantalate is an important material for optical waveguides.
- The formula for sodium tantalate is NaTaO₃.

Learning
Memory Aids
Mnemonic
Think: 'TANTALum' (the metal) + '-ATE' (a common ending for salts, like 'carbonATE'). So, a 'tantalATE' is a salt made from tantalum.
Conceptual Metaphor
None applicable. The term is purely denotative.
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with 'танталовый' (tantalum, adjective). 'Tantalate' is 'танталат', a specific chemical term.
- Avoid literal translation attempts; it is a fixed technical noun.
Common Mistakes
- Misspelling as 'tantalite' (which is a different mineral, (Fe,Mn)Ta₂O₆).
- Mispronouncing with stress on the third syllable (/tænˈtæləleɪt/). Stress is on the first syllable.
- Using it as a verb (e.g., 'to tantalate' does not exist).

FAQ
Frequently Asked Questions
No, it is a highly specialized term used only in chemistry and materials science.
No. There is no verb 'to tantalate'. The related verb for the process might be 'to form a tantalate' or 'to synthesize a tantalate'.
'Tantalate' is a general term for salts of tantalic acid (e.g., LiTaO₃). 'Tantalite' is a specific black mineral ore, (Fe,Mn)Ta₂O₆, from which tantalum is extracted.
Absolutely not. It is only necessary for learners specializing in advanced chemistry, metallurgy, or materials engineering.
