1. Hoʻohana nui ʻia ʻo Cerium Oxide, i kapa ʻia hoʻi ʻo Ceria, i ke aniani, nā keramika a me ka hana ʻana i nā mea hoʻouluulu.
2.I ka ʻoihana aniani, ua manaʻo ʻia ʻo ia ka mea hoʻopili aniani kūpono loa no ka hoʻopili optical kikoʻī.
3. Hoʻohana ʻia hoʻi ia e hoʻokaʻawale i ke kala o ke aniani ma ka mālama ʻana i ka hao i kona kūlana ferrous. Hoʻohana ʻia ka hiki o ke aniani i hoʻopili ʻia me Cerium e ālai i ka mālamalama ultra violet i ka hana ʻana i nā aniani lapaʻau a me nā puka makani aerospace.
4. Hoʻohana ʻia nō hoʻi ia e pale i ka pouli ʻana o nā polymers i ka lā a e kāohi i ka hoʻololi ʻana o ke aniani kīwī.
5. Hoʻopili ʻia ia i nā ʻāpana optical e hoʻomaikaʻi i ka hana. Hoʻohana pū ʻia nā Ceria maʻemaʻe kiʻekiʻe i nā phosphors a me ka dopant i ke kristal.
