Definition
Meaning
A rare mineral, consisting primarily of zirconium dioxide (ZrO2).
A dense, hard, and typically brownish mineral that is the principal ore of zirconium and hafnium, found in silica-poor igneous rocks and carbonatites.
Linguistics
Semantic Notes
The term is used almost exclusively within mineralogy, geology, materials science, and related industrial contexts. It is a proper noun derived from a person's name and refers to a specific, defined mineral species.

Examples
By CEFR Level
- Baddeleyite is an important source of zirconium.
- Scientists sometimes find baddeleyite in certain types of rock.
- The age of the rock was determined using uranium-lead dating of baddeleyite grains.
- Due to its high melting point, synthetic baddeleyite is used in refractory ceramics.

N/A (Highly technical term with no common metaphorical application.)
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with 'циркон' (zircon), a different zirconium silicate mineral. The direct equivalent is 'бадделеит'.
Common Mistakes
- Misspelling as 'baddleyite', 'baddeleite', or 'baddelyite'.
- Mispronouncing with stress on the third syllable.
- Confusing it with the more common mineral 'zircon'.

FAQ
Frequently Asked Questions
Primarily as an ore for extracting zirconium and hafnium. Synthetic zirconium dioxide derived from it is used in refractory materials, ceramics, and oxygen sensors.
No, it is a relatively rare mineral compared to other zirconium-bearing minerals like zircon.
It is named after the British geologist and chemist Joseph Baddeley.
No. While it can form crystals, they are not typically of gem quality and are valued for scientific and industrial purposes, not jewellery.
