Scandium oxide, nemakemikariSc2O3, is a white solid inonyungudika mumvura uye inopisa acid. Nekuda kwekuomerwa kwekuburitsa zvakananga scandium zvigadzirwa kubva ku scandium ine zvicherwa, scandium oxide parizvino inonyanya kudzoserwa uye kutorwa kubva kune-zvigadzirwa zve scandium ine zvicherwa zvakaita semarara emarara, tsvina, utsi, uye madhaka matsvuku.
Strategic products
Scandiumchinhu chakakosha hurongwa chigadzirwa. Pakutanga, Dhipatimendi reMukati reUS rakaburitsa runyorwa rwemakumi matatu neshanu ezvicherwa (akakosha zvicherwa) anoonekwa akakosha kuhupfumi hweUS uye kuchengetedzeka kwenyika (Final Rondedzero yeCritical Minerals 2018). Zvinenge zvese zvicherwa zvehupfumi zvinosanganisirwa, senge aruminiyamu inoshandiswa muindasitiri, platinamu boka simbi dzinoshandiswa mukugadzira zvinokonzeresa, zvisingawanzo pasi zvinhu zvinoshandiswa muzvigadzirwa zvemagetsi, tini uye titanium inoshandiswa mukugadzira alloy, nezvimwe.
Kushandiswa kweScandium oxide
Single scandium inowanzo shandiswa muma alloys, uye scandium oxide inoitawo basa rakakosha muceramic zvinhu. Semuyenzaniso, tetragonal zirconia ceramic zvinhu zvinogona kushandiswa se electrode zvinhu kune yakasimba oxide mafuta masero ane chinhu chakakosha. Iko conductivity yeiyi electrolyte inowedzera nekuwedzera kwekushisa uye oksijeni kutenderera munzvimbo. Nekudaro, chimiro chekristaro chechinhu ichi checeramic pachacho hachigone kuvepo chakasimba uye hachina kukosha kwemaindasitiri; inofanira kuvharwa nezvimwe zvinhu zvinogona kugadzirisa chimiro ichi kuitira kuchengetedza zvinhu zvepakutanga. Kuwedzera 6-10% ye scandium oxide yakafanana nekongiri chimiro, inobvumira scandium oxide kuti igadzikane pane sikweya lattice.
Scandium oxide inogona zvakare kushandiswa se densifier uye stabilizer kune yakakwirira-simba, yakakwirira-tembiricha-inodzivirira engineering ceramic zvinhu silicon nitride. Inogona kuburitsa refractory phase Sc2Si2O7 pamucheto wezvimedu zvakanaka, nekudaro ichidzikisa kuderedzwa kwepamusoro-tembiricha yeinjiniya ceramics. Kuenzaniswa nekuwedzera mamwe maokisi, inogona kuvandudza yakakwira-tembiricha michina yesilicon nitride. Kuwedzera huwandu hushoma hweSc2O3 kuUO2 mune yakakwirira-tembiricha reactor nyukliya mafuta anogona kudzivirira kushanduka kwelatisi, kuwedzera kwevhoriyamu uye kutsemuka kunokonzerwa nekushandurwa kweUO2 kuenda kuU3O8.
Scandium oxide inogona kushandiswa sechinhu chinoputika chesemiconductor coatings. Scandium oxide inogona zvakare kushandiswa kugadzira inoshanduka-wavelength solid-state lasers, yakakwirira-tsananguro yeterevhizheni erekitironi pfuti, simbi halide marambi, nezvimwe.
Industry Analysis
Mumakore achangopfuura, scandium oxide yakakwezva kutarisisa kwakawanda mumunda weakasimba oxide mafuta maseru (SOFC) uye scandium sodium halogen marambi. SOFC ine mabhenefiti epamusoro pesimba rekugadzira simba, kukwirira kusanganiswa, kuchengetedza zviwanikwa zvemvura, girinhi kuchengetedza kwezvakatipoteredza, nyore modular kuungana, uye kuwanda kwesarudzo yemafuta. Iyo ine yakakura kukosha kwekushandisa muminda yekugovaniswa kwemagetsi ekugadzira, emagetsi mabhatiri emagetsi, ekuchengetedza simba mabhatiri, nezvimwe.
