tungstate
LowScientific/Technical
Definition
Meaning
A salt or ester of tungstic acid, containing the WO₄²⁻ anion.
Any of a series of compounds formed by the reaction of tungsten oxide (WO₃) with a base, or any mineral containing the tungstate ion, used in various industrial and technological applications.
Linguistics
Semantic Notes
Primarily a chemistry and materials science term. It refers specifically to compounds, not the element tungsten itself. The term is countably used for specific salts (e.g., sodium tungstate) and also used uncountably to refer to the class of compounds.

Memory Aids
Mnemonic
Think: TUNGSTen + -ATE (like 'carbonATE') = a salt made from tungsten.
Conceptual Metaphor
N/A (Highly technical term with little metaphorical extension).
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with 'вольфрамат' (wolframate), which is a direct synonym but less common in modern English. The element 'tungsten' is 'вольфрам' in Russian, but the compound 'tungstate' is still 'тангат' or 'вольфрамат'.
Common Mistakes
- Using 'tungstate' to refer to pure tungsten metal. Incorrect pluralisation (it is usually uncountable for the class, but 'tungstates' is correct for multiple types).

FAQ
Frequently Asked Questions
No. Tungsten is the chemical element (W). Tungstate refers to a compound containing tungsten and oxygen, typically in the form of a salt (WO₄²⁻ ion).
Yes. Several important tungsten ores, such as scheelite (calcium tungstate) and wolframite (an iron-manganese tungstate), are naturally occurring tungstate minerals.
Tungstates are used in industrial catalysts, pigments, fireproofing fabrics, X-ray screens (calcium tungstate), and in the production of certain types of glass and ceramics.
No, the standard pronunciation /ˈtʌŋsteɪt/ is essentially identical in both major variants.
