Yttrium Substitutes: Alternatives and Trade-offs
Facts checked against sources on . How we check facts.
Yttrium can be replaced in some applications and not in others. For electronics, lasers and phosphors, USGS names yttrium is generally not subject to direct substitution by other elements. It names substitutes for 2 applications in all, and the table below gives its wording for each, including where a substitute costs performance or does not exist.
4 of 4
official critical minerals lists (US, EU, Australia, Canada) that include yttrium
What is yttrium used for?
- Ceramics and phosphors: the leading domestic and global end uses
- Lasers: yttrium-aluminum-garnet crystals in lasers for communication, industrial and medical applications
- Other uses: fiber optics, optical glass, pigments, and as a stabilizer in zirconia ceramics
Which materials can replace yttrium?
| Application | Substitute and trade-off |
|---|---|
| Electronics, lasers and phosphors | Yttrium is generally not subject to direct substitution by other elements |
| Stabilizer in zirconia ceramics | Calcium oxide or magnesium oxide, which generally impart lower toughness |
