Kugwiritsa ntchito
Cerium chloride heptahydrate, mu mitundu ya crystalline aggregates kapena kuwala chikasu mtanda aggregates, ndi zinthu zofunika chothandizira, galasi, phosphors ndi kupukuta ufa. Amagwiritsidwanso ntchito kuyeretsa galasi posunga chitsulo mu ferrous state. Kutha kwa magalasi a Cerium-doped kutsekereza kuwala kwa ultra violet kumagwiritsidwa ntchito popanga zida zamagalasi azachipatala ndi mawindo apamlengalenga. Amagwiritsidwanso ntchito kuteteza ma polima kuti asade ndi kuwala kwa dzuwa komanso kupondereza magalasi a kanema wawayilesi kuti asasinthe. Amagwiritsidwa ntchito pazigawo za kuwala kuti apititse patsogolo ntchito. Cerium chloride ndi used m'mafakitale monga zopangira petroleum, zotengera magalimoto utsi, wapakatikati mankhwala, etc. Amagwiritsidwanso ntchito popanga zitsulo cerium, etc. Cerium kolorayidi ntchito m'mafakitale monga mankhwala intermediates, cerium mchere zopangira, zolimba aloyi zina, ndi mankhwala. reagents
