He aha ka mea e hoʻohana ʻia ai ʻo Cerium(III) Carbonate?
Hoʻohana ʻia ʻo Cerium(III) Carbonate i ka hana ʻana o ka cerium(III) chloride, a i loko o nā kukui incandescent. Hoʻohana ʻia ʻo Cerium Carbonate i ka hana ʻana i ka catalyst auto a me ke aniani, a ma ke ʻano he mea maka no ka hana ʻana i nā hui Cerium ʻē aʻe. I ka ʻoihana aniani, ua manaʻo ʻia ʻo ia ka mea hoʻopili aniani kūpono loa no ka hoʻopili optical pololei. Hoʻohana ʻia hoʻi 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 ʻo Cerium e pale aku i ka mālamalama ultra violet i ka hana ʻana i nā aniani lapaʻau a me nā puka makani aerospace. Loaʻa koke ʻo Cerium Carbonate i ka hapa nui o nā nui. Hoʻomaikaʻi ka maʻemaʻe kiʻekiʻe a me nā ʻano maʻemaʻe kiʻekiʻe i ka maikaʻi optical a me ka pono e like me nā kūlana ʻepekema.
Ma ke ala, ʻo nā noi kalepa he nui no ka cerium e komo pū me ka metallurgy, ke aniani a me ka polishing aniani, nā keramika, nā catalysts, a me nā phosphors. I ka hana kila, hoʻohana ʻia ia e wehe i ka oxygen manuahi a me ka sulfur ma o ka hana ʻana i ka oxysulfide paʻa a ma ke kāʻei ʻana i nā mea trace pono ʻole, e like me ke kēpau a me ka antimony.
