Yttrium: Overview
Ceramics and phosphors: where yttrium quietly does its work
What this tab covers What the commodity is used for, why, in what volumes and with what alternatives, and its chain from mine or field to end user. Also the latest price moves, top recent news, three things to know, and buttons into each tab.Key uses
| Use | Share | Annual volume | Why this commodity | Alternatives |
|---|---|---|---|---|
| Ceramics: yttria-stabilised zirconia for thermal-barrier coatings, sensors, dental and structural parts, plus plasma-resistant coatings in chip tools | 72% | about 7,200-10,800 t Y2O3 a yearbasis | Yttria keeps zirconia in its tough, stable crystal form from room temperature to over 1,000 C. That makes it the standard coating on jet-engine and gas-turbine blades, the electrolyte in oxygen sensors, and the base of dental crowns. Yttrium oxide coatings also protect semiconductor etch chambers. Calcia or magnesia can stabilise zirconia but give lower toughness (USGS). EU CRM study 2023; USGS MCS 2026; Reuters via AJOT (Nov 2025) | Calcia- or magnesia-stabilised zirconia (lower toughness) Ceria-stabilised zirconia Alumina or other ceramic coatings in some chip-tool parts |
| Automotive catalysts | 9% | about 900-1,350 t Y2O3 a yearbasis | Yttrium is added to the oxide supports of exhaust catalysts to keep their surface area stable at high temperature. This helps the precious metals stay active over the life of the car. The share is small but tied to vehicle output. EU CRM study 2023 | Lanthanum, cerium and zirconium oxide stabilisers Other catalyst-support formulations |
| Metals and alloys (magnesium, aluminium and superalloys) | 7% | about 700-1,050 t Y2O3 a yearbasis | Small additions of yttrium improve oxidation resistance in nickel superalloys and strength and creep resistance in magnesium alloys. The Aerospace Industries Association calls yttrium essential to advanced jet engines. Magnesium alloys with lanthanides, yttrium and zirconium also replace older magnesium-thorium alloys in aerospace (USGS). EU CRM study 2023; USGS MCS 2026 (Thorium); Reuters via AJOT (Nov 2025) | Other rare-earth additions (cerium, lanthanum, neodymium) Hafnium or zirconium in some superalloys |
| Glass and optics (optical glass, fibre optics) | 4% | about 400-600 t Y2O3 a yearbasis | Yttrium raises the refractive index and heat resistance of specialty glass, and is used in optical fibre and lens glass. Volumes are modest but quality requirements are tight, so buyers tend to stick with qualified suppliers. EU CRM study 2023; USGS MCS 2026 | Lanthanum and other rare-earth oxides in optical glass |
| Other: phosphors, YAG laser crystals, pigments, superconductors | 8% | about 800-1,200 t Y2O3 a yearbasis | Yttrium hosts europium in red phosphors and forms yttrium-aluminium-garnet crystals for industrial, medical and communication lasers. USGS lists phosphors with ceramics as the leading uses worldwide, and says yttrium in lasers and phosphors generally cannot be directly replaced. Phosphor demand has fallen as LEDs replaced fluorescent lamps. EU CRM study 2023; USGS MCS 2026 | Other host lattices for phosphors (in LEDs) Other laser crystals (for example vanadate or fibre lasers) |
From mine to user
- 1. Mining of ion-adsorption clays or heavy-mineral sands Southern China and Burma leach yttrium-rich clays; mineral-sand operations in the US, India and Malaysia recover monazite and xenotime.
- 2. Concentrate or mixed carbonate Clays give a mixed rare-earth carbonate; sands give monazite and xenotime concentrates. Yttrium is only about 0.12% of rare earths in Mountain Pass bastnaesite (USGS).
- 3. Cracking and leaching Concentrates are dissolved in acid or alkali to put the rare earths into solution and reject thorium and phosphate.
- 4. Solvent-extraction separation Hundreds of mixer-settler stages separate yttrium from other rare earths. China did nearly all of this in 2025 (EU CRM 2023: 100% of processing).
- 5. Oxide, metal and compounds Yttrium oxide (99.999%) averaged $9/kg FOB China in 2025; metal $40/kg (Argus via USGS). China exported about 1,600 t Y2O3 equivalent in 2025.
- 6. Powders, coatings and alloys Zirconia powder makers, coating shops, phosphor and laser crystal growers and alloy producers turn the oxide into products.
- 7. End users Jet-engine and gas-turbine makers, chip-tool suppliers, dentists, carmakers, optics and laser companies.
