Ka hoʻohana ʻana i ka pauka scandium oxide Sc2O3

Ka hoʻohana ʻana i ka scandium oxide

ʻO Sc2O3 ke kumu kemika o ka scandium oxide. Nā waiwai: Paʻa keʻokeʻo. Me ke ʻano cubic o ka honua sesquioxide. ʻO ka mānoanoa 3.864. Ka helu hehee 2403 ℃ 20 ℃. ʻAʻole hiki ke hoʻoheheʻe ʻia i ka wai, hiki ke hoʻoheheʻe ʻia i ka wai wela. Hoʻomākaukau ʻia e ka decomposition thermal o ka paʻakai scandium. Hiki ke hoʻohana ʻia e like me ka mea evaporation no ka uhi semiconductor. E hana i ka laser paʻa me ka lōʻihi o ka nalu ʻokoʻa, ka pū uila TV wehewehe kiʻekiʻe, ke kukui halide metala, etc.

ʻO Scandium oxide (Sc2O3) kekahi o nā huahana scandium koʻikoʻi. Ua like kona mau waiwai kino a me na mea o ka honua oxides (e like me La2O3, Y2O3 a me Lu2O3, etc.), no laila, ua like loa ke ano hana i hoohana ia i ka hana. Hiki iā Sc2O3 ke hana i ka metala Scandium (sc), nā paʻakai like ʻole (ScCl3,ScF3,ScI3,Sc2(C2O4)3, a pēlā aku) a me nā ʻāpana scandium like ʻole (Al-Sc,Al-Zr-Sc series). Loaʻa i kēia mau huahana scandium ka waiwai ʻenehana kūpono a me ka hopena waiwai maikaʻi. Ua hoʻohana nui ʻia ʻo Sc2O3 i ka alumini alumini, ke kukui uila, laser, catalyst, activator, ceramics, aerospace a pēlā aku ma muli o kona mau hiʻohiʻona. I kēia manawa, hōʻike ʻia ke kūlana noi o Sc2O3 ma ke kahua o ka alloy, ke kukui uila, catalyst, activator a me nā ceramics ma Kina a me ka honua.

(1) ka hoʻohana ʻana i ka mea hao

I kēia manawa, ʻo ka Al-Sc alloy i hana ʻia o Sc a me Al he mau mea maikaʻi o ka haʻahaʻa haʻahaʻa (SC = 3.0g/cm3, Al = 2.7g/cm3, ikaika kiʻekiʻe, kiʻekiʻe paʻakikī, plasticity maikaʻi, kūpaʻa ikaika a me ka paʻa wela, etc. No laila, ua hoʻohana maikaʻi ʻia i nā ʻāpana hoʻolālā o nā missiles, aerospace, aviation, nā kaʻa a me nā moku, a huli mālie i ka hoʻohana kīwila, e like me nā lima o nā hāmeʻa haʻuki (hockey a me ka baseball) Loaʻa iā ia nā ʻano o ka ikaika kiʻekiʻe. , ʻoʻoleʻa kiʻekiʻe a me ke kaumaha māmā, a he waiwai kūpono.

Hoʻokani nui ʻo Scandium i ka hana o ka hoʻololi ʻana a me ka hoʻomaʻemaʻe ʻana i ka palaoa i loko o ka alloy, e alakaʻi ana i ka hoʻokumu ʻana o ke ʻano ʻano Al3Sc hou me nā waiwai maikaʻi loa. Ua hoʻokumu ʻo Al-Sc alloy i kahi moʻo o ka alloy series, no ka laʻana, ua hōʻea ʻo Rūsia i 17 mau ʻano o Al-Sc series, a ua loaʻa iā Kina kekahi mau alloys (e like me Al-Mg-Sc-Zr a me Al-Zn-Mg-Sc huila). ʻAʻole hiki ke hoʻololi ʻia nā hiʻohiʻona o kēia ʻano mea e nā mea ʻē aʻe, no laila mai ka manaʻo o ka hoʻomohala ʻana, He mea nui ka hoʻomohala ʻana o kāna noi a me ka hiki, a ua manaʻo ʻia e lilo i noi nui i ka wā e hiki mai ana. No ka laʻana, ua hoʻomohala ʻo Rūsia i ka hana ʻenehana a hoʻomohala wikiwiki no nā ʻāpana hana māmā, a ke wikiwiki nei ʻo Kina i kāna noiʻi a me ka noi ʻana, ʻoi aku hoʻi i ka aerospace a me ka mokulele.

(2) ka hoʻohana ʻana i nā kumu kukui uila hou

Hoʻololi ʻia ʻo Sc2O3 maʻemaʻe i ScI3, a laila hana ʻia i ke kolu o ka hanauna hou o ke kukui uila me NaI, i hana ʻia i ke kukui halogen scandium-sodium no ke kukui (ma kahi o 0.1mg~ 10mg o Sc2O3≥99% mea i hoʻohana ʻia no kēlā me kēia kukui. Ma lalo o ka hana o ka uila kiʻekiʻe, ʻo ka laina scandium spectral he uliuli a he melemele ka laina spectral sodium, a hui pū nā kala ʻelua me kekahi e hana i ka mālamalama kokoke i ka lā. mālama i ka ikehu, ola lōʻihi a me ka mana wāwahi o ka noe.

(3) Hoʻohana i nā mea laser

Hiki ke hoʻomākaukau ʻia ʻo Gadolinium gallium scandium garnet (GGSG) ma ka hoʻohui ʻana i ka Sc2O3≥ 99.9% maʻemaʻe i ka GGG, a ʻo kona haku ʻana he ʻano Gd3Sc2Ga3O12. ʻO ka mana hoʻokuʻu o ke kolu o ka hanauna laser i hana ʻia he 3.0 mau manawa kiʻekiʻe ma mua o ka laser me ka leo like, i hiki i kahi mana kiʻekiʻe a me ka miniaturized laser device, hoʻonui i ka mana o ka laser oscillation a hoʻomaikaʻi i ka hana o ka laser. . Ke hoʻomākaukau nei i hoʻokahi aniani, ʻo kēlā me kēia uku he 3kg ~ 5kg, a ma kahi o 1.0kg o nā mea maka me Sc2O3≥99.9% e hoʻohui ʻia. I kēia manawa, hoʻohana nui ʻia kēia ʻano laser i ka ʻenehana koa, a ua hoʻoneʻe ʻia hoʻi i ka ʻoihana kīwila. Mai ka hiʻohiʻona o ka hoʻomohala ʻana, loaʻa iā ia ka mana nui i ka hoʻohana kaua a me ka hoʻohana kīwila i ka wā e hiki mai ana.

(4) ka hoʻohana ʻana i nā mea uila

Hiki ke hoʻohana ʻia ʻo Sc2O3 maʻemaʻe e like me ka oxidation cathode activator no ka cathode electron gun o ka pahu kiʻi TV kala me ka hopena maikaʻi. E kāpī i kahi papa o Ba, Sr a me Ca oxide me ka mānoanoa o hoʻokahi milimita ma ka cathode o ka paipu kala, a laila e hoʻopuehu i kahi papa o Sc2O3 me ka mānoanoa o 0.1 millimeter ma luna. I loko o ka cathode o ka papa oxide, Mg a me Sr pane me Ba, e paipai i ka emi o Ba, a me na electrons i hoʻokuʻu 'ia ua oi ikaika, e haawi ana i ka nui o keia manawa electrons, i ka phosphor emit malamalama. Hoʻohālikelike me ka cathode me ka Sc2O3 uhi. , hiki iā ia ke hoʻonui i ka nui o kēia manawa e 4 mau manawa, e hoʻomaʻamaʻa i ke kiʻi TV a hoʻolōʻihi i ke ola cathode e 3 mau manawa. ʻO ka nui o Sc2O3 i hoʻohana ʻia no kēlā me kēia 21-inch hoʻomohala cathode ʻo 0.1mg I kēia manawa, ua hoʻohana ʻia kēia cathode ma kekahi mau ʻāina o ka honua, e like me Iapana, hiki ke hoʻomaikaʻi i ka mākeke hoʻokūkū a hoʻolaha i ke kūʻai ʻana o nā pahu TV.
