Ukusetyenziswa kwe-scandium oxide

Ifomula yekhemikhali ye-scandium oxide yi-Sc2O3. Iimpawu: Okuqinileyo okumhlophe. Ngesakhiwo se-cubic sesquioxide yomhlaba enqabileyo. Uxinaniso 3.864. Indawo yokunyibilika 2403℃ 20℃. Ayinyibiliki emanzini, inyibilika kwiasidi eshushu. Ilungiswa ngokubola kwe-thermal yetyuwa ye-scandium. Ingasetyenziswa njengezinto zokukhupha umoya kwi-semiconductor coating. Yenza i-laser eyomeleleyo enobude obuguquguqukayo, inkcazo ephezulu yompu we-electron weTV, isibane se-metal halide, njl.

I-Scandium oxide (Sc2O3) yenye yezona mveliso zibalulekileyo ze-scandium. Iimpawu zayo ezibonakalayo kunye neekhemikhali zifana nezo ze-oxides zomhlaba ezinqabileyo (ezifana ne-La2O3, Y2O3 kunye ne-Lu2O3, njl.), ngoko ke iindlela zokuvelisa ezisetyenziswa kwimveliso zifana kakhulu. I-Sc2O3 inokuvelisa iScandium yensimbi (sc), iityuwa ezahlukeneyo (ScCl3, ScF3,ScI3,Sc2(C2O4)3, njl.) kunye ne-alloys ezahlukeneyo ze-scandium (Al-Sc,Al-Zr-Sc series). Ezi mveliso ze-scandium zinexabiso lobugcisa obusebenzayo kunye nefuthe elihle loqoqosho.Sc2O3 isetyenziswe ngokubanzi kwi-aluminium alloy, umthombo wokukhanya kombane, i-laser, i-catalyst, i-activator, i-ceramics, i-aerospace kunye nokunye ngenxa yeempawu zayo. Okwangoku, imeko yesicelo se-Sc2O3 kwiinkalo ze-alloy, umthombo wokukhanya kombane, i-catalyst, i-activator kunye ne-ceramics e-China kunye nehlabathi lichazwe kamva.

(1) ukusetyenziswa kwe-alloy

Okwangoku, i-alloy ye-Al-Sc eyenziwe nge-Sc kunye ne-Al ineenzuzo zokuxinana okuphantsi (SC = 3.0g / cm3, Al = 2.7g / cm3, amandla aphezulu, ubunzima obuphezulu, iplastiki elungileyo, ukuxhathisa okuqinileyo kwe-corrosion kunye nokuzinza kwe-thermal, njl. Ngoko ke, isetyenziswe kakuhle kwiindawo zezakhiwo zemijukujelwa, i-aerospace, i-aviation, iimoto kunye neenqanawa, kwaye ngokuthe ngcembe yajika yaba ngabantu. sebenzisa, njengeziphatho zezixhobo zemidlalo (ihoki kunye nebaseball)Ineempawu zamandla aphezulu, ubungqongqo obuphezulu kunye nobunzima obulula, kwaye inexabiso elikhulu.

I-Scandium idlala indima enkulu yokuguqulwa kunye nokucocwa kweenkozo kwi-alloy, ekhokelela ekuqulunqweni kohlobo olutsha lwe-Al3Sc eneempawu ezintle. I-al-Sc ialloy yenze uluhlu lwe-alloy series, umzekelo, iRashiya ifikelele kwiindidi ezili-17 ze-Al-Sc series, kwaye i-China ine-alloys ezininzi (ezifana ne-Al-Mg-Sc-Zr kunye ne-Al-Zn-Mg-Sc. ingxubevange). Iimpawu zolu hlobo lwe-alloy azikwazi ukutshintshwa zezinye izinto, ngoko ke ngokombono wophuhliso, uphuhliso lwesicelo salo kunye namandla amakhulu, kwaye kulindeleke ukuba ibe sisicelo esikhulu kwixesha elizayo. Ngokomzekelo, iRashiya inemveliso yemizi-mveliso kwaye iphuhliswe ngokukhawuleza kwiindawo zesakhiwo sokukhanya, kwaye i-China ikhawuleza uphando kunye nokusetyenziswa kwayo, ngakumbi kwi-aerospace kunye ne-aviation.

(2) ukusetyenziswa kwezinto ezintsha zombane wokukhanya

I-Sc2O3 ecocekileyo yatshintshwa yaba yi-ScI3, yaza emva koko yenziwa kwisizukulwana esitsha sesithathu semathiriyeli yokukhanya yombane kunye ne-NaI, eyathi yacutshungulwa yaba sisibane se-halogen se-scandium-sodium sokukhanyisa (malunga ne-0.1mg~ 10mg ye-Sc2O3≥99% imathiriyeli yayisetyenziselwa isibane ngasinye. Ngaphantsi kwesenzo sombane ophezulu, umgca we-scandium spectral uhlaza okwesibhakabhaka kwaye umgca we-sodium spectral uphuzi, kunye nemibala emibini. sebenzisane omnye nomnye ukuvelisa ukukhanya kufutshane nokukhanya kwelanga.Ukukhanya kuneengenelo zokukhanya okuphezulu, umbala wokukhanya okulungileyo, ukonga amandla, ubomi obude kunye namandla okuqhekeza inkungu eyomeleleyo.

(3) Ukusetyenziswa kwezixhobo ze-laser

I-Gadolinium gallium scandium garnet (GGSG) inokulungiswa ngokongeza i-Sc2O3≥ ecocekileyo ye-99.9% kwi-GGG, kwaye ukubunjwa kwayo luhlobo lwe-Gd3Sc2Ga3O12. Amandla okukhutshwa kwe-laser yesizukulwana sesithathu enziwe ngayo amatyeli angama-3.0 aphezulu kunalawo e-laser enomthamo ofanayo, ofikelele kumandla aphezulu kunye nesixhobo se-laser esincinci, sandise amandla okuphuma kwe-laser oscillation kunye nokuphucula ukusebenza kwelaser. . Xa ulungiselela ikristale enye, intlawulo nganye yi-3kg ~ 5kg, kwaye malunga ne-1.0kg yezinto eziluhlaza kunye ne-Sc2O3≥99.9% zongezwa. Okwangoku, olu hlobo lwe-laser lusetyenziswa kakhulu kwitekhnoloji yasemkhosini, kwaye ngokuthe ngcembe lutyhalwa kushishino lwabahlali. Ngokwembono yophuhliso, inamandla amakhulu kusetyenziso lomkhosi kunye noluntu kwixesha elizayo.

(4) ukusetyenziswa kwezinto zombane

I-Sc2O3 ecocekileyo ingasetyenziswa njenge-activator ye-oxidation ye-cathode ye-cathode electron gun yombala wetyhubhu ye-TV enesiphumo esihle. Tshaza umaleko we-Ba, Sr kunye ne-Ca oxide enobunzima bemilimitha enye kwi-cathode yombhobho wombala, kwaye emva koko usasaze umaleko we-Sc2O3 kunye nobukhulu be-0.1 millimeter kuyo. Kwi-cathode yomaleko we-oxide, i-Mg kunye ne-Sr isabela kunye ne-Ba, ekhuthaza ukucuthwa kwe-Ba, kunye nee-electron ezikhutshweyo zisebenza ngakumbi, zikhupha ii-electron ezinkulu zangoku, okwenza i-phosphor ikhuphe ukukhanya.Xa kuthelekiswa ne-cathode ngaphandle kwe-Sc2O3 yokwambathisa , inokunyusa ubuninzi bangoku ngamaxesha angama-4, yenza umfanekiso weTV ucace ngakumbi kwaye wandise ubomi be-cathode ngamaxesha e-3. Isixa se-Sc2O3 esisetyenziselwa i-cathode nganye yokuphuhlisa i-intshi ye-21 yi-0.1mg Okwangoku, le cathode isetyenziswe kumazwe athile ehlabathini, njengeJapan, enokuphucula ukukhuphisana kweemarike kunye nokukhuthaza ukuthengiswa kweesethi zeTV.
