- Kang digunakake kanggo kalebu flints kanggo korek rokok.
- Sawijining senyawa Cerium (Gerah) oksida digunakake minangka katalis; sijine nang tembok saka open minangka ngalangi saka buildup saka ampas masak.
- Sampeyan uga dipigunakaké ing insecticides, alami rambute lan minangka aditif anti-nuthuk kanggo bensin. Nanging kabeh iki dilarang déning pamaréntah minangka logam Lead dikenal kanggo ngrugekake kanggo kesehatan.
