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 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 mea maʻalahi loa e 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.
