Ukusetyenziswa kwe-scandium oxide Sc2O3 powder

Ukusetyenziswa kwe-scandium oxide

Ifomula yemichiza yeiscandium oxideyi 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 kwiingxubevange aluminiyam, 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, izithuthi kunye neenqanawa, kwaye ngokuthe ngcembe iguqukele ekusebenziseni uluntu, njengezibambo zezixhobo zemidlalo (ihoki kunye ne-baseball)Inempawu zamandla aphezulu. , ubungqongqo obuphezulu kunye nobunzima obulula, kwaye buxabiseke kakhulu.

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

UnyuluSc2O3yaguqulwa yaba yi-ScI3, yaza ke yenziwa yasisizukulwana esitsha sesithathu semathiriyeli yomthombo wokukhanya wombane nge-NaI, eyathi yalungiselelwa kwisibane se-halogen se-scandium-sodium sokukhanyisa (malunga ne-0.1mg~ 10mg ye-Sc2O3≥99% imathiriyeli yasetyenziswa kwisibane ngasinye. isenzo samandla ombane aphezulu, umgca we-scandium spectral unombala oluhlaza okwesibhakabhaka kunye nomgca we-sodium spectral utyheli, kwaye imibala emibini iyasebenzisana ukuvelisa ukukhanya kufutshane nokukhanya kwelanga.Ukukhanya kunenzuzo yokukhanya okuphezulu, umbala wokukhanya okulungileyo, ukonga amandla. , ubomi obude kunye namandla okuqhekeza inkungu.

(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.Tshiza umaleko we-Ba, Sr kunye ne-Ca oxide enobunzima bemilimitha enye kwi-cathode yombhobho wombala, kwaye emva koko usasaze umaleko weSc2O3kunye nobunzima 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.
