Scandiumhe mea laha ole a waiwai i loaa ka noonoo nui i na makahiki i hala iho nei no kona mau waiwai pono like ole.Ua ʻike ʻia no kāna mau waiwai māmā a me ka ikaika kiʻekiʻe, e lilo ia i mea i ʻimi ʻia i nā ʻoihana e like me ka aerospace, electronics a me ka ikehu hou.Eia naʻe, ma muli oscandium'O ka li'ili'i a me ke kumu kū'ai ki'eki'e, he mea pa'akikī kona 'ohi 'ana a me ka ho'oma'ema'e 'ana.ʻO kekahi ala i ʻimi ʻia ʻo ia ka hoʻohuliscandium oxidei lokometala scandium.Akā hikiscandium oxidee hoʻomaʻemaʻe maikaʻi ʻia i lokometala scandium?
Scandium oxideʻo ia ke ʻano maʻamau oscandiumloaa ma ke ano.He pauka keʻokeʻo i hana pinepine ʻia ma ke ʻano he huahana i ka hana ʻana i nā ores e like me ka uranium, tin a me ka tungsten.ʻOiaiscandium oxideLoaʻa iā ia kekahi mau noi i ka ʻoihana seramika, aia kona hiki ke hoʻololi ʻia i lokometala scandium.
Hoʻomaka ka hana hoʻomaʻemaʻe me ka hana ʻana oscandium oxidea komo pū kekahi mau ʻanuʻu.ʻO ka mea mua, lawe ʻia ka ʻaila scandium mai ka lepo a loaʻa i nā kaʻina hana pono e hoʻokaʻawale i nā mea waiwai mai nā haumia.Hoʻomaʻamaʻa hou ʻia ka concentrate e hana i ka maʻemaʻe kiʻekiʻescandium oxidepauda.
Once kascandium oxideloaʻa, ʻo ka hana aʻe e hoʻohuli iā ia i lokometala scandium.Loaʻa kēia hoʻololi ma o ke kaʻina hana i kapa ʻia ka hoʻēmi ʻana.Ua noiʻi ʻia nā ʻano hana hoʻohaʻahaʻa like ʻole, akā ʻo ke ala maʻamau e pili ana i ka hoʻohana ʻana i ka metala calcium ma ke ʻano he mea hoʻemi.Scandium oxideua hui pū ʻia me ka calcium a laila hoʻomehana ʻia i nā wela kiʻekiʻe i loko o kahi ʻūhā a i ʻole i loko o kahi lewa inert.Hoʻopili kēia i ka calcium me ka oxygen i lokoscandium oxide, ka hopena o ka hoʻokumu ʻana o ka calcium oxide a memetala scandium.
Eia naʻe, hoʻomaʻemaʻescandium oxidei loko o ka metala scandium ʻaʻole ia he hana maʻalahi.No ka hōʻoiaʻiʻo ʻana i ka hoʻololi kūleʻa, aia kekahi mau pilikia e pono e lanakila.ʻO kekahi o nā pilikia nui aia i ka reactivity kiʻekiʻe o scandium.ScandiumHiki ke hana maʻalahi me ka oxygen, nitrogen a me ka makū i ka lewa, hiki ke maʻalahi i ka oxidation a me ka haumia.No laila, pono e mālama pono ʻia ke kaʻina hana hōʻemi e pale i nā hopena i makemake ʻole ʻia a mālama i ka maʻemaʻe o ka metala scandium i loaʻa.
ʻO kekahi pilikia ʻo ke kumukūʻai kiʻekiʻe o ka hana ʻana i kametala scandium.No ka meascandiumʻAʻole liʻiliʻi ma ke ʻano, ʻo kāna ʻili ʻana a me ka hoʻomaʻemaʻe ʻana e koi i ka ʻenehana kiʻekiʻe a me nā mea hana kūikawā, e hopena i nā kumukūʻai kiʻekiʻe.Kahi mea hou aʻe,scandiumke hoʻomau nei ka lohi ʻana o ka noi, ke koi hou aku nei i lunascandiumkumukūʻai.
ʻOiai kēia mau pilikia, ke hoʻomau nei mākou i ka hana noiʻi a me ka hana hoʻomohala e hoʻomaikaʻi i ka pono a me ka maikaʻi o ke kumukūʻaimetala scandiumhana ʻana.Ke manaʻo nei kēia mau hana e hoʻomaʻamaʻa i ke kaʻina hana hoʻomaʻemaʻe a hoʻomohala i nā ʻano hana hoʻomau a ʻoi aku ka maikaʻi o ka hoʻokele waiwai no ka unuhi ʻana a me ka hoʻomaʻemaʻe scandium.
I ka hōʻuluʻulu manaʻo,scandium oxidehiki ke hoʻomaʻemaʻe i lokometala scandiumma o ka hoemi ana.Eia naʻe, ʻaʻohe pilikia o kēia hoʻololi ʻana ma muli oscandium'o ka hana hou 'ana a me nā koina hana ki'eki'e e pili ana i ka unuhi a me ka ho'oma'ema'e 'ana.Ke holomua nei ka ʻenehana a me ke koiscandiumpiʻi, hiki i nā kaʻina hana hoʻomaʻemaʻe e hiki mai ana ke lilo i ʻoi aku ka maikaʻi a me ke kumu kūʻai, hanametala scandiumhe mea maʻalahi a hoʻohana nui ʻia ma waena o nā ʻoihana.
