Ulah lan Wuku
- 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.
- Iki digunakake minangka agen ngurangi nalika nyiapake logam kaya thorium lan uranium. Uga digunakake minangka agen paduan kanggo logam kayata aluminium, tembaga lan timbal.
- Kalsium karbonat utawa watu gamping digunakake ing semen.
