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 kubantu abavamile. ukusetshenziswa, njengezibambo zemishini yezemidlalo (ihokhi kanye ne-baseball)Inezici zamandla aphezulu, ukuqina okuphezulu nesisindo esilula, futhi inenani elikhulu elisebenzayo.

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 wesizukulwane sesithathu nge-NaI, eyacutshungulwa yaba ilambu le-halogen le-scandium-sodium 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 anamandla okunqanda inkungu.

(3) Ukusetshenziswa kwezinto 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.
