Kushandiswa kwe scandium oxide Sc2O3 poda

Kushandiswa kwe scandium oxide

Iyo kemikari formula yescandium oxideiri Sc2O3. Properties: White yakasimba. Iine cubic chimiro che isingawanzo pasi sesquioxide. Density 3.864. Melting point 2403 ℃ 20 ℃. Insoluble mumvura, soluble mune inopisa asidhi. Inogadzirwa nekupisa kwekuora kwe scandium munyu. Inogona kushandiswa se evaporation zvinhu zve semiconductor coating. Gadzira yakasimba laser ine inosiyana wavelength, yakakwira tsananguro yeTV erekitironi pfuti, simbi halide rambi, nezvimwe.

Scandium oxide (Sc2O3) ndechimwe chezvinhu zvakakosha zve scandium zvigadzirwa. Hunhu hwayo hwepanyama uye hwemakemikari hwakafanana neaya asingawanzo pasi oxides (seLa2O3,Y2O3 uye Lu2O3, nezvimwewo), saka nzira dzekugadzira dzinoshandiswa mukugadzira dzakafanana. Sc2O3 inogona kugadzira simbi Scandium (sc), munyu akasiyana (ScCl3,ScF3,ScI3,Sc2(C2O4)3, nezvimwewo) uye akasiyana scandium alloys (Al-Sc,Al-Zr-Sc akatevedzana). Izvi zvigadzirwa zve scandium zvine hutekinoroji kukosha uye yakanaka yehupfumi mhedzisiro.Sc2O3 yakashandiswa zvakanyanya mukatialuminium alloy, magetsi emwenje sosi, laser, catalyst, activator, ceramics, aerospace uye zvichingodaro nekuda kwehunhu hwayo. Parizvino, chimiro chekushandisa cheSc2O3 muminda yealloy, magetsi emwenje sosi, catalyst, activator uye ceramics muChina nenyika inotsanangurwa gare gare.

(1) kushandiswa kwechisanganiswa

Parizvino, iyo Al-Sc alloy yakagadzirwa neSc neAl ine zvakanakira yepasi density (SC = 3.0g/cm3, Al = 2.7g/cm3, kusimba kwepamusoro, kuomarara kwepamusoro, kunaka kwepurasitiki, kusimba kwakasimba kwecorrosion uye kugadzikana kwekupisa, etc. Naizvozvo, yakashandiswa zvakanaka muzvikamu zvekuumbwa zvezvombo zvinokandwa, aerospace, avhiyesheni, motokari uye zvikepe, uye zvishoma nezvishoma zvakatendeukira kune vanhuwo zvavo. shandisa, senge mabatiro emidziyo yemitambo (hockey nebaseball)Iyo ine hunhu hwekusimba kwepamusoro, kusimba kwepamusoro uye huremu huremu, uye yakakosha hukuru hunoshanda.

Scandium inonyanya kuita basa rekugadzirisa uye kukwenenzvera zviyo mualloy, izvo zvinotungamira mukuumbwa kwechikamu chitsva cheAl3Sc mhando ine zvivakwa zvakanaka. Al-Sc alloy yakagadzira nhevedzano yealloy series, semuenzaniso, Russia yasvika gumi nenomwe marudzi eAl-Sc akatevedzana, uye China zvakare ine akati wandei alloys (akadai seAl-Mg-Sc-Zr neAl-Zn-Mg-Sc. alloy). Hunhu hwemhando iyi yealloy hahugone kutsiviwa nezvimwe zvinhu, saka kubva padanho rekusimudzira, Kuvandudzwa kwayo kwekushandisa uye kugona kwakakura, uye inotarisirwa kuve chishandiso chikuru mune ramangwana. Semuyenzaniso, Russia ine kugadzirwa kwemaindasitiri uye yakagadziridzwa nekukasira kune zvikamu zvechiedza, uye China iri kumhanyisa tsvakiridzo nekushandiswa kwayo, kunyanya mundege nendege.

(2) kushandiswa kwezvinhu zvitsva zvemagetsi magetsi

PureSc2O3yakashandurwa kuita SCI3, ichibva yaitwa chizvarwa chitsva chechitatu chemagetsi mwenje sosi zvinhu neNaI, iyo yakagadziridzwa kuita scandium-sodium halogen rambi rekuvhenekesa (inenge 0.1mg~ 10mg yeSc2O3≥99% zvinhu zvakashandiswa pamwenje wega wega. kuita kwemagetsi akakwira, scandium spectral line iblue uye sodium spectral line ndeyeyero, uye mavara maviri aya anobatirana kuburitsa chiedza. pedyo nechiedza chezuva.Chiedza chine zvakanakira kupenya kwepamusoro, ruvara rwechiedza chakanaka, kuchengetedza simba, hupenyu hurefu uye simba rakasimba rekupwanya mhute.

(3) Kushandiswa kwelaser materials

Gadolinium gallium scandium garnet (GGSG) inogona kugadzirwa nekuwedzera yakachena Sc2O3≥ 99.9% kuGGG, uye kuumbwa kwayo ndeyeGd3Sc2Ga3O12 mhando. Simba rekuburitsa rechitatu chizvarwa laser rakagadzirwa naro rakakwira zvakapetwa katatu pane iro relaser ine vhoriyamu imwechete, iyo yasvika kune yakakwirira-simba uye miniaturized laser mudziyo, yakawedzera simba rekubuda relaser oscillation uye yakavandudza mashandiro elaser. . Paunenge uchigadzira kristaro imwe chete, mutero wega wega 3kg ~ 5kg, uye inenge 1.0kg yezvigadzirwa zvine Sc2O3≥99.9% inowedzerwa. Parizvino, iyi mhando yelaser inoshandiswa zvakanyanya muhunyanzvi hwemauto, uye zvakare inosundirwa zvishoma nezvishoma kuindasitiri yevagari. Kubva pakuona kwebudiriro, ine mukana mukuru mukushandiswa kwechiuto uye kwevanhuwo zvavo mune ramangwana.

(4) kushandiswa kwezvinhu zvemagetsi

Yakachena Sc2O3 inogona kushandiswa seoxidation cathode activator ye cathode electron pfuti yeruvara TV yepikicha chubhu ine hunhu hwakanaka. Pfaya chidimbu cheBa, Sr uye Ca oxide nehupamhi hwemirimita imwe pane cathode yechubhu yeruvara, wobva waparadzira dhiri reSc2O3nehupamhi hwe 0.1 millimeter pairi. Mune cathode ye oxide layer, Mg uye Sr vanoita neBa, iyo inokurudzira kuderedzwa kweBa, uye maerekitironi akasunungurwa anowedzera kushanda, achipa maerekitironi makuru emazuva ano, izvo zvinoita kuti phosphor ibudise chiedza. Inofananidzwa ne cathode pasina Sc2O3 coating. , inogona kuwedzera huwandu hwazvino ne4 nguva, kuita kuti mufananidzo weTV ujeke uye urebe hupenyu hwekathode ne3 nguva. Nhamba yeSc2O3 inoshandiswa kune yega yega 21-inch inovandudza cathode ndeye 0.1mg Parizvino, iyi cathode yakashandiswa mune dzimwe nyika pasi rose, dzakadai seJapan, iyo inogona kuvandudza kukwikwidzana kwemusika uye kukurudzira kutengesa kweTV seti.
