Kushandiswa kwe scandium oxide
Iyo kemikari formula ye scandium oxide ndeye 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 nemakemikari hwakafanana neasingawanzo pasi oxides (seLa2O3,Y2O3 neLu2O3, 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 hunokosha uye yakanaka yehupfumi effect.Sc2O3 yakashandiswa zvakanyanya mualuminium alloy, electric light source, 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, ndege, ndege, motokari uye ngarava, uye zvishoma nezvishoma yakashandura kushandiswa kwevanhu, semabatiro emidziyo yemitambo (hockey nebaseball)Iine hunhu hwesimba guru. , kuomarara kwepamusoro uye uremu hureru, uye hunokosha 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
Pure Sc2O3 yakashandurwa kuita ScI3, ndokuzoitwa 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. .Pasi pekuita kwehigh voltage, scandium spectral line iblue uye sodium spectral line ndeyeyero, uye mavara maviri aya anobatirana kuti abudise chiedza pedyo nechiedza chezuva.Chiedza chine zvakanakira kupenya kwepamusoro, kupenya kwakanaka kwemavara, 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, uye woparadzira chidimbu cheSc2O3 nehukobvu hwe0.1 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.
