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 99.99%

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.

scandium alloy

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.
