Cerium nwere ọtụtụ ojiji:
(1) Dịka ihe mgbakwunye n'ime iko,seriumnwere ike ịmịkọrọ radieshon ultraviolet na infrared, nke na-eme ka a na-eji ya eme ihe nke ọma n'ime iko ụgbọala. Nke a abụghị naanị na ọ na-echebe megide radieshon ultraviolet kamakwa ọ na-ebelata okpomọkụ dị n'ime ụgbọala, si otú a na-echekwa ike eji eme ihe maka ntụ oyi. Kemgbe 1997, iko ụgbọala niile dị na Japan etinyela cerium oxide, na 1996, United States riri ihe karịrị tọn 1,000 nkeserium oxidemaka iko ụgbọala.
(2)SeriumA na-eji ya ugbu a na ihe ndị na-eme ka gas na-ekpochapụ ụgbọala dị ọcha, na-egbochi nnukwu mwepụ nke gas na-ekpochapụ ụgbọala n'ime ikuku. Na United States, oriri cerium maka ebumnuche a bụ otu ụzọ n'ụzọ atọ nke mkpokọta oriri ụwa a na-adịghị ahụkebe.
(3) Cerium sulfide nwere ike dochie ọla ndị nwere ike imebi gburugburu ebe obibi dịka lead na cadmium n'ime agba, nke dabara adaba maka agba plastik, yana n'ime ụlọ ọrụ agba, ink, na akwụkwọ.
