Hoʻohana ʻia ka Europium(iii) oxide, i kapa ʻia ʻo Europia, ma ke ʻano he phosphor activator, color cathode-ray tubes a me ka wai-crystal displays i hoʻohana ʻia i nā monitor computer a me nā televise e hoʻohana i ka Europium Oxide ma ke ʻano he phosphor ʻulaʻula; ʻaʻohe mea i ʻike ʻia. Hoʻohana nui ʻia ʻo Europium Oxide (Eu2O3) ma ke ʻano he phosphor ʻulaʻula i nā keʻena kīwī a me nā kukui fluorescent, a ma ke ʻano he mea hoʻoikaika no nā phosphor-based Yttrium. Hoʻohana ʻia ʻo Europium Oxide no ka hana ʻana i ka pauka fluorescent no nā paipu kiʻi kala, ka lepo tricolor fluorescent pauda no nā kukui, X-ray intensifying screen activators, etc. nā kukui mercury.
Kaumaha pūʻulu: 1000,2000Kg.
Hoʻopili ʻia：I loko o ka pahu kila me nā ʻeke PVC pālua i loko o ka ʻupena 50Kg i kēlā me kēia.
Nānā:Hiki ke hoʻopilikino ʻia ka maʻemaʻe pili, nā lepo lepo ʻole, nā lepo lepo ʻole a me nā hōʻailona ʻē aʻe e like me nā koi o ka mea kūʻai aku.
