Ukusetshenziswa kwe-scandium oxide Sc2O3 powder

Ukusetshenziswa kwe-scandium oxide

Ifomula yamakhemikhali yei-scandium oxidengi Sc2O3.Izakhiwo: Okuqinile okumhlophe.Ngesakhiwo se-cubic se-sesquioxide yomhlaba engavamile.Ukuminyana 3.864.Iphoyinti lokuncibilika 2403 ℃ 20 ℃.Ayincibiliki emanzini, incibilika ku-asidi eshisayo.Ilungiselelwe ukubola okushisayo kwe-scandium kasawoti.Ingasetshenziswa njengempahla yokuhwamuka kwe-semiconductor coating.Yenza i-laser eqinile enobude obuguquguqukayo, isibhamu se-electron ye-TV esichaza kakhulu, isibani sensimbi se-halide, njll.

I-Scandium oxide (Sc2O3) ingenye yemikhiqizo ebaluleke kakhulu ye-scandium.Izakhiwo zayo ezingokomzimba namakhemikhali zifana nalezo zama-oxides omhlaba angavamile (njenge-La2O3,Y2O3 kanye ne-Lu2O3, njll.), ngakho-ke izindlela zokukhiqiza ezisetshenziswa ekukhiqizeni zifana kakhulu.I-Sc2O3 ingakhiqiza i-Scandium yensimbi (sc), usawoti ohlukile (ScCl3,ScF3,ScI3,Sc2(C2O4)3, njll.) kanye nama-alloys ahlukahlukene e-scandium (Al-Sc,Al-Zr-Sc series).Le mikhiqizo ye-scandium inenani lobuchwepheshe elisebenzayo kanye nomphumela omuhle wezomnotho.Sc2O3 isetshenziswe kabanzi kuingxube ye-aluminium, umthombo wokukhanya kagesi, i-laser, i-catalyst, i-activator, i-ceramics, i-aerospace nokunye ngenxa yezici zayo.Njengamanje, isimo sokusetshenziswa kwe-Sc2O3 emikhakheni ye-alloy, umthombo wokukhanya kagesi, i-catalyst, i-activator kanye ne-ceramics e-China nasemhlabeni kuchazwe kamuva.

(1) ukusetshenziswa kwengxubevange

Njengamanje, ingxubevange ye-Al-Sc eyenziwe nge-Sc ne-Al inezinzuzo zokuminyana okuphansi (SC = 3.0g/cm3, Al = 2.7g/cm3, amandla aphezulu, ubulukhuni obuphezulu, ipulasitiki enhle, ukumelana nokugqwala okuqinile nokuzinza kokushisa, njll. Ngakho-ke, isetshenziswe kahle ezingxenyeni zesakhiwo semicibisholo, i-aerospace, izindiza, izimoto nemikhumbi, futhi kancane kancane yaphendukela ekusetshenzisweni kwabantu, njengezibambo zemishini yezemidlalo (i-hockey ne-baseball)Inezici zamandla aphezulu. , iqinile futhi inesisindo esincane, futhi inenani elikhulu elingokoqobo.

I-Scandium idlala kakhulu indima yokuguqulwa kanye nokucoliswa okusanhlamvu ku-alloy, okuholela ekwakhekeni kohlobo olusha lwe-Al3Sc lwesigaba esinezakhiwo ezinhle kakhulu.Ingxubevange ye-Al-Sc yenze uchungechunge lwe-alloy series, isibonelo, iRussia isifinyelele izinhlobo eziyi-17 zochungechunge lwe-Al-Sc, kanti i-China nayo inama-alloys amaningana (njenge-Al-Mg-Sc-Zr kanye ne-Al-Zn-Mg-Sc. ingxubevange).Izici zalolu hlobo lwe-alloy azikwazi ukushintshwa ezinye izinto, ngakho-ke ngokombono wokuthuthuka, ukuthuthukiswa kokusetshenziswa kwayo namandla amakhulu, futhi kulindeleke ukuthi ibe uhlelo lokusebenza olukhulu ngokuzayo.Isibonelo, i-Russia inokukhiqiza okuthuthukisiwe futhi yathuthukiswa ngokushesha ezingxenyeni zesakhiwo esikhanyayo, futhi i-China isheshisa ucwaningo lwayo nokusebenzisa, ikakhulukazi emkhathini wezindiza kanye nezindiza.

(2) ukusetshenziswa kwezinto ezintsha zomthombo wokukhanya kagesi

OkumsulwaI-Sc2O3yaguqulwa yaba yi-ScI3, yase yenziwa into entsha yomthombo wokukhanya kagesi yesizukulwane sesithathu nge-NaI, eyacutshungulwa yaba ilambu le-scandium-sodium halogen ukuze likhanyise (cishe u-0.1mg~ 10mg we-Sc2O3≥99% impahla yasetshenziswa isibani ngasinye. Ngaphansi isenzo samandla kagesi aphezulu, umugqa we-scandium spectral uluhlaza okwesibhakabhaka futhi umugqa we-sodium spectral uphuzi, futhi imibala emibili iyasebenzisana ukuze ikhiqize ukukhanya eduze nokukhanya kwelanga.Ukukhanya kunezinzuzo zokukhanya okuphezulu, umbala omuhle wokukhanya, ukonga amandla. , impilo ende namandla anqamula inkungu.

(3) Ukusetshenziswa kwezisetshenziswa ze-laser

I-Gadolinium gallium scandium garnet (GGSG) ingalungiswa ngokwengeza i-Sc2O3≥ 99.9% emsulwa ku-GGG, futhi ukwakheka kwayo kuwuhlobo lwe-Gd3Sc2Ga3O12.Amandla okukhishwa kwelaser yesizukulwane sesithathu enziwe ngayo aphakeme ngokuphindwe izikhathi ezingu-3.0 kunalawo e-laser enevolumu efanayo, efinyelele kudivayisi ye-laser enamandla amakhulu kanye ne-miniaturized, andise amandla okukhipha i-laser oscillation futhi yathuthukisa ukusebenza kwe-laser. .Lapho ulungiselela ikristalu eyodwa, inkokhelo ngayinye ingu-3kg~ 5kg, futhi cishe u-1.0kg wezinto zokusetshenziswa ezine-Sc2O3≥99.9% ziyengezwa.Njengamanje, lolu hlobo lwe-laser lusetshenziswa kabanzi kwezobuchwepheshe bezempi, futhi kancane kancane luphushelwa embonini yabantu.Ngokombono wentuthuko, inamandla amakhulu ekusetshenzisweni kwezempi kanye nezakhamuzi esikhathini esizayo.

(4) ukusetshenziswa kwezinto zikagesi

I-Sc2O3 ehlanzekile ingasetshenziswa njengesiqalisi se-cathode ye-oxidation yesibhamu se-cathode electron yeshubhu yesithombe ye-TV enombala enomphumela omuhle.Fafaza ungqimba lwe-Ba, Sr kanye ne-Ca oxide enogqinsi lwemilimitha eyodwa ku-cathode yeshubhu lombala, bese uhlakaza ungqimba lwe-I-Sc2O3enogqinsi oluyimilimitha elingu-0.1 kuyo.Ku-cathode yongqimba lwe-oxide, i-Mg ne-Sr isabela nge-Ba, ekhuthaza ukuncishiswa kwe-Ba, futhi ama-electron akhululiwe asebenza kakhulu, anikeze ama-electron amakhulu amanje, okwenza i-phosphor ikhiphe ukukhanya.Uma kuqhathaniswa ne-cathode ngaphandle kwe-Sc2O3 coating. , ingakhuphula ukuminyana kwamanje izikhathi ezi-4, yenza isithombe se-TV sicace futhi andise impilo ye-cathode izikhathi ezi-3.Inani le-Sc2O3 elisetshenziselwa i-cathode ngayinye ekhulayo engama-intshi angu-21 ngu-0.1mg Njengamanje, le cathode isetshenziswe kwamanye amazwe emhlabeni, njenge-Japan, engathuthukisa ukuncintisana kwemakethe futhi ikhuthaze ukuthengiswa kwamasethi we-TV.
