Scandium (Sc)
Metala scandium (palapala ʻikepili)
Ke hoʻohālikelike ʻia me nā mea yttrium a me ka lanthanide, loaʻa i ka scandium kahi radius ionic liʻiliʻi a me kahi alkalinity nāwaliwali loa o ka hydroxide.No laila, ke hui pū ʻia nā mea scandium a me nā mea ʻokoʻa honua, e kahe mua ka scandium ke mālama ʻia me ka amonia (a i ʻole ka alkali dilute loa), no laila hiki ke maʻalahi ke hoʻokaʻawale ʻia mai nā mea o ka honua ma ke ʻano o ka "fractional precipitation".ʻO kekahi ala ʻē aʻe, ʻo ia ka hoʻohana ʻana i ka decomposition polarization o ka nitrate no ka hoʻokaʻawale ʻana.
Hiki ke loaʻa iā Sc ma ka electrolysis.Hoʻoheheʻe ʻia ʻo ScCl3, KCl a me LiCl i ka hoʻomaʻemaʻe scandium, a hoʻohana ʻia ka zinc i hoʻoheheʻe ʻia ma ke ʻano he cathode no ka electrolysis, no laila e hoʻoheheʻe ʻia ka scandium ma ka electrode zinc, a laila e hoʻoheheʻe ʻia ka zinc no ka loaʻa ʻana o ka scandium.Eia kekahi, hiki ke hoʻihoʻi hou ʻia ka scandium i ka wā e hoʻoili ai i ka ʻaila e hana i nā mea uranium, thorium a me lanthanide.ʻO ka hoʻihoʻi piha ʻana o ka scandium pili mai ka tungsten a me ka tin ore kekahi o nā kumu nui o ka scandium. ʻO Scandium ka maia wale nō ma ke ʻano trivalent i loko o ka pūhui, hiki ke hoʻoheheʻe ʻia i Sc2O3 i ka lewa a nalowale kona ʻulaʻula metala a lilo i hina ʻeleʻele.
ʻO nā hoʻohana nui o ka scandium:
(1) Hiki i ka Scandium ke hana me ka wai wela e hoʻokuʻu i ka hydrogen, a hiki ke hoʻoheheʻe ʻia i ka waikawa, no laila he mea hoʻemi ikaika ia.
(2) He alkaline wale nō ka Scandium oxide a me ka hydroxide, akā ʻaʻole hiki ke hoʻoheheʻe ʻia kona lehu paʻakai.ʻO Scandium chloride he aniani keʻokeʻo, hiki ke hoʻoheheʻe ʻia i ka wai a me ka deliquescent i ka lewa. (3) I loko o ka ʻoihana metallurgical, hoʻohana pinepine ʻia ka scandium e hana i nā alloys (nā mea hoʻohui o nā alloys) e hoʻomaikaʻi ai i ka ikaika, ka paʻakikī, ka pale ʻana i ka wela a me ka hana ʻana o nā alloys.ʻO kahi laʻana, hiki i ka hoʻohui ʻana i kahi scandium liʻiliʻi i ka hao i hoʻoheheʻe ʻia e hiki ke hoʻomaikaʻi nui i nā waiwai o ka hao, ʻoiai ka hoʻohui ʻana i kahi scandium liʻiliʻi i ka alumini hiki ke hoʻomaikaʻi i kona ikaika a me ka pale wela.
(4) I ka ʻoihana uila, hiki ke hoʻohana ʻia ka scandium e like me nā mea semiconductor like ʻole.No ka laʻana, ʻo ka hoʻohana ʻana i ka scandium sulfite i nā semiconductor ua hoihoi i ka nānā ʻana ma ka home a ma waho, a ʻo ka ferrite i loaʻa i ka scandium ke hoʻohiki nei hoʻi i loko.nā koʻikoʻi magnetic computer.
(5) I loko o ka ʻoihana kemika, hoʻohana ʻia ka scandium compound e like me ka dehydrogenation waiʻona a me ka dehydration agent, he mea hoʻoikaika maikaʻi no ka hana ʻana o ka ethylene a me ka chlorine mai ka waika hydrochloric ʻōpala.
(6) I ka ʻoihana aniani, hiki ke hana ʻia nā aniani kūikawā i loaʻa i ka scandium.
(7) I loko o ka ʻoihana kukui uila, scandium a me nā kukui sodium i hana ʻia me ka scandium a me ka sodium i nā mea maikaʻi o ka maikaʻi kiʻekiʻe a me ke kala kukui maikaʻi.
(8) Loaʻa ka Scandium ma ke ʻano o 45Sc ma ke ʻano.Eia kekahi, aia ʻeiwa radioactive isotopes o Scandium, ʻo ia hoʻi 40 ~ 44Sc a me 46 ~ 49Sc.I waena o lākou, 46Sc, ma ke ʻano he tracer, ua hoʻohana ʻia i ka ʻoihana kemika, metallurgy a me ka moana.I ka lāʻau lapaʻau, aia kekahi poʻe ma waho e aʻo e hoʻohana ana i ka 46Sc e mālama i ka maʻi kanesa.
