ʻO nā ʻano unuhi o scandium

Nā ʻano unuhi oscandium

No ka manawa lōʻihi ma hope o ka loaʻa ʻana, ʻaʻole i hōʻike ʻia ka hoʻohana ʻana i ka scandium ma muli o kona paʻakikī i ka hana ʻana.Me ka hoʻonui nui ʻana o nā ʻano hana hoʻokaʻawale ʻana o ka honua, aia i kēia manawa ke kahe kaʻina hana no ka hoʻomaʻemaʻe ʻana i nā pūhui scandium.No ka mea ʻoi aku ka nāwaliwali o ka scandium i hoʻohālikelike ʻia me nā mea yttrium a me ka lanthanide, ua loaʻa i ka hydroxides nā minerala hui pū ʻia me ka scandium.Ma hope o ka mālama ʻana, e kahe mua ka scandium hydroxide i ka wā e hoʻoneʻe ʻia i ka hopena a mālama ʻia me ka amonia.No laila, hiki i ka hoʻohana ʻana i ke ʻano o ka ua ua hiki ke hoʻokaʻawale maʻalahi iā ia mai nā mea ʻano honua.ʻO kekahi ala ʻē aʻe ʻo ia ka hoʻohana ʻana i ka decomposition hierarchical o ka nitrate no ka hoʻokaʻawale ʻana, ʻoiai ʻo ka waikawa nitric ka maʻalahi o ka decompose a hiki ke hoʻokō i ke kumu o ka hoʻokaʻawale ʻana i ka scandium.Eia kekahi, ʻo ka hoʻihoʻi piha ʻana o ka scandium i ka uranium, tungsten, tin a me nā waihona mineral ʻē aʻe kekahi kumu nui o ka scandium.

Ma hope o ka loaʻa ʻana o kahi pūhui scandium maʻemaʻe, ua hoʻololi ʻia i ScCl3 a hoʻoheheʻe ʻia me KCI a me LiCI.Hoʻohana ʻia ka zinc i hoʻoheheʻe ʻia ma ke ʻano he cathode no ka electrolysis, e hoʻoneʻe ana i ka scandium i ka electrode zinc.A laila, hoʻopau ʻia ka zinc no ka loaʻa ʻana o ka scandium metala.He metala keʻokeʻo keʻokeʻo māmā kēia, a ʻoi aku ka ikaika o kāna mau mea kemika.Hiki iā ia ke hana me ka wai wela e hana i ka hydrogen.

ScandiumLoaʻa nā waiwai o ka haʻahaʻa pili haʻahaʻa (kokoke like me ka alumini) a me ka helu heheʻe kiʻekiʻe.ʻO ka Nitriding (SCN) kahi helu heheʻe o 2900 ℃ a me ka conductivity kiʻekiʻe, e hoʻohana nui ʻia i nā ʻoihana uila a me nā lekiō.ʻO Scandium kekahi o nā mea no ka thermonuclear reactors.Hiki i ka Scandium ke hoʻoulu i ka phosphorescence o ka ethane a hoʻonui i ke kukui polū o ka magnesium oxide.Ke hoʻohālikelike ʻia me nā kukui mercury kiʻekiʻe, ʻoi aku ka maikaʻi o nā kukui sodium ʻoi e like me ke kukui kiʻekiʻe a me ke kala kukui maikaʻi, e kūpono ai no ke kiʻi ʻana i nā kiʻiʻoniʻoni a me nā kukui plaza.

Hiki ke hoʻohana ʻia ʻo Scandium ma ke ʻano he mea hoʻohui no nā nickel chromium alloys i ka ʻoihana metallurgical e hana i nā ʻāpana wela wela.He mea koʻikoʻi ka Scandium no nā papa ʻike submarine.ʻO ka wela wela o ka scandium a hiki i 5000 ℃, hiki ke hoʻohana ʻia i ka ʻenehana ākea.Hiki ke hoʻohana ʻia ʻo Sc no ka ʻimi radioactive no nā kumu like ʻole.Hoʻohana ʻia ʻo Scandium i ka lāʻau lapaʻau.
