Scandium oxyde, hamwe na formulaire ya chimiqueSc2O3, ni igiti cyera gishobora gushonga mumazi na aside ishyushye. Bitewe ningorane zo gukuramo ibicuruzwa bya scandium muri scandium irimo amabuye y'agaciro, okiside ya scandium kuri ubu iragarurwa kandi ikurwa mu bicuruzwa biva muri scandium irimo amabuye y'agaciro nk'ibisigazwa by'imyanda, amazi mabi, umwotsi, n'ibyondo bitukura.
Ibicuruzwa byingenzi
Scandiumni igicuruzwa cyingenzi. Mbere, Minisiteri y’ubutegetsi bw’Amerika yasohoye urutonde rw’amabuye y'agaciro 35 (amabuye y'agaciro akomeye) afatwa nk'ingirakamaro mu bukungu bwa Amerika n'umutekano w'igihugu (Urutonde rwa nyuma rw'amabuye y'agaciro 2018). Amabuye y'agaciro hafi ya yose arimo ubukungu arimo, nka aluminiyumu ikoreshwa mu nganda, ibyuma bya platine matsinda akoreshwa mu gukora catalizator, ibintu bidasanzwe by'ubutaka bikoreshwa mu bikoresho bya elegitoroniki, amabati na titanium bikoreshwa mu gukora amavuta, n'ibindi.
Gukoresha Scandium Oxide
Scandium imwe ikoreshwa muri alloys, kandi okiside ya scandium nayo igira uruhare runini mubikoresho byubutaka. Kurugero, tetragonal zirconia ceramic ibikoresho bishobora gukoreshwa nkibikoresho bya electrode ya selile ikomeye ya oxyde ifite ibintu byihariye. Ubworoherane bwiyi electrolyte bwiyongera hamwe no kwiyongera kwubushyuhe hamwe nubushakashatsi bwa ogisijeni mubidukikije. Nyamara, imiterere ya kristu yibi bikoresho byubutaka ubwayo ntishobora kubaho neza kandi nta gaciro k’inganda; igomba gukopororwa hamwe nibintu bimwe na bimwe bishobora gutunganya iyi miterere kugirango ibungabunge ibintu byumwimerere. Ongeramo 6-10% ya scandium oxyde ni nkimiterere ifatika, ituma okiside ya scandium ihagarara kumurongo wa kare.
Okiside ya Scandium irashobora kandi gukoreshwa nka densifier na stabilisateur kugirango imbaraga nyinshi, zihanganira ubushyuhe bwo hejuru bwubukorikori bwa ceramic material silicon nitride. Irashobora kubyara icyiciro cya Sc2Si2O7 kuruhande rwibice byiza, bityo bikagabanya ihindagurika ryubushyuhe bwo hejuru bwubukorikori. Ugereranije no kongeramo izindi oxyde, irashobora kurushaho kunoza ubushyuhe bwo hejuru bwa mashini yanitride. Ongeraho umubare muto wa Sc2O3 kuri UO2 mumavuta ya kirimbuzi yubushyuhe bwo hejuru burashobora kwirinda guhinduranya lattice, kwiyongera kwijwi no guturika biterwa no guhindura UO2 kuri U3O8.
Scandium oxyde irashobora gukoreshwa nkibikoresho byo guhumeka kuri semiconductor. Okiside ya Scandium irashobora kandi gukoreshwa mugukora impinduka-yumurambararo ukomeye-ya lazeri, imbunda ndende ya tereviziyo ya elegitoronike, amatara ya halide, nibindi.
Isesengura ry'inganda
Mu myaka yashize, okiside ya scandium yakwegereye abantu benshi mu bijyanye n’ingirabuzimafatizo zikomeye zo mu rugo (SOFC) hamwe n’amatara ya sodium halogen. SOFC ifite ibyiza byo kubyara ingufu nyinshi, gukora neza cyane, kubungabunga umutungo wamazi, kurengera ibidukikije bibisi, guteranya modular byoroshye, hamwe no guhitamo peteroli. Ifite agaciro gakomeye mubikorwa mubice byo gukwirakwiza amashanyarazi, bateri yimodoka, bateri zibika ingufu, nibindi.
