Ulah lan Wuku
- Wis cenderung kanggo njaluk tarnished ing online mbukak, nanging nalika alloyed karo unsur kaya erbium, vanadium, tingkat atose sudo.
- senyawa kaya Erbium oxide digunakake ing kaca tingal safety saka welders lan buruh metal.
- Logam rhodium utamane digunakake ing konverter katalitik kanggo mobil amarga nyuda oksida nitrogen ing gas buang.
- Iki digunakake minangka katalis industri kanggo asam nitrat, asam asetat, reaksi hidrogenasi, lsp.
