Mu iterambere rirambye ry’inganda n’ikoranabuhanga rigezweho, imikorere y’ibikoresho igira uruhare runini. Cyane cyane iyo habayeho imbogamizi z’ubushyuhe bwinshi, imikorere y’ibikoresho igira ingaruka zitaziguye ku mikorere n’igihe bimara ibikoresho n’ibicuruzwa bifitanye isano.Ibicuruzwa bya karubide ya silikoni, hamwe n’ubushyuhe bwazo bwiza cyane, buhoro buhoro zigenda ziba amahitamo meza ku bintu byinshi bikoreshwa mu bushyuhe bwinshi.
Karubide ya silikoni, mu buryo bw'imiterere ya shimi, ni ikintu kigizwe n'ibintu bibiri: silikoni (Si) na karuboni (C). Uru ruvange rudasanzwe rwa atome rutuma karubide ya silikoni iba ifite imiterere yihariye y'umubiri n'iya shimi. Imiterere yayo ya kristu irahamye cyane, kandi atome zifitanye isano rya hafi binyuze mu migozi ya covalent, bigatuma karubide ya silikoni iba ifite imbaraga zikomeye zo kuyihuza imbere, ari na yo shingiro ry'ubushyuhe bwayo bukabije.
Iyo twibanze ku bikorwa bifatika, inyungu yo kurwanya ubushyuhe bwinshi bw'ibicuruzwa bya silicon carbide igaragara neza. Mu rwego rw'amatanura yo mu nganda ashyushye cyane, ibikoresho gakondo byometseho bishobora koroha, guhinduka, ndetse no kwangirika iyo bihuye n'ubushyuhe bwinshi igihe kirekire, ibyo bikaba bigira ingaruka ku mikorere isanzwe y'itanura ahubwo bigasaba gusimburwa kenshi, bikongera ikiguzi n'ingorane zo kubungabunga. Ibikoresho byometseho silicon carbide ni nko gushyira "ikoti ririnda" rikomeye ku itanura. Ku bushyuhe buri hejuru ya 1350 ℃, bishobora gukomeza kugira imiterere ihamye n'imiti kandi ntibizoroha cyangwa ngo byoroshye kubora. Ibi ntibyongera gusa igihe cyo gukora kw'amatanura no kugabanya inshuro zo kuyatunganya, ahubwo binatuma amatanura yo mu nganda akora neza kandi mu buryo buhamye mu bidukikije bishyushye cyane, bitanga garanti yizewe yo gukora.
Urugero, mu kirere, iyo indege ziguruka ku muvuduko wo hejuru, zitanga ubushyuhe bwinshi binyuze mu gukururana gukomeye n'ikirere, bigatera kwiyongera gukomeye k'ubushyuhe bwo hejuru. Ibi bisaba ko ibikoresho bikoreshwa mu ndege bigomba kuba bifite ubushobozi bwo guhangana n'ubushyuhe bwinshi, bitabaye ibyo bizahura n'ibibazo bikomeye by'umutekano. Ibikoresho bigizwe na silicon carbide byabaye ibikoresho by'ingenzi mu gukora ibice by'ingenzi nk'ibice bya moteri y'indege na sisitemu zo kurinda ubushyuhe bw'indege bitewe n'ubudahangarwa bwabyo bwiza mu bushyuhe bwinshi. Bishobora kugumana imikorere myiza ya mekanike mu gihe cy'ubushyuhe bwinshi, kwemeza ko imiterere y'ibice ikora neza, gufasha indege gutsinda umuvuduko n'ubushyuhe, no kugera ku iguruka ryiza kandi ritekanye.
Ukurikije imiterere ya mikorosikopi, ibanga ryo kudakomera ku bushyuhe bwinshi bwa silicon carbide riri mu miterere yayo ya kristu n'imiterere yayo ya shimi. Nkuko byavuzwe mbere, ingufu z'imibanire hagati ya atome za silicon carbide ni nyinshi cyane, bigatuma atome zidahita ziva mu myanya yazo mu bushyuhe bwinshi, bityo bigatuma imiterere y'ibikoresho igumana ubushyuhe. Byongeye kandi, ingano y'ubushyuhe ya silicon carbide iba nke, kandi ingano yayo iba nto iyo ubushyuhe buhindutse cyane, bigatuma birinda ikibazo cyo kuvunika kw'ibikoresho guterwa n'ubwinshi bw'imihangayiko bitewe no kwaguka no guhindagurika k'ubushyuhe.
Bitewe n’iterambere rikomeje ry’ikoranabuhanga, imikorere y’ibicuruzwa bya silicon carbide nayo ikomeje gutera imbere. Abashakashatsi banonosoye uburyo bwo gutegura, batunganya ibikoresho, n’ubundi buryo bwo kuzamura ubushobozi bwo kurwanya ubushyuhe bwinshi bw’ibicuruzwa bya silicon carbide, ndetse banagura ubushobozi bwo kubikoresha mu nzego nyinshi. Mu gihe kizaza, twizera ko ibicuruzwa bya silicon carbide bizatanga ubushyuhe mu nganda nyinshi nko mu ngufu nshya, ibikoresho by’ikoranabuhanga, n’ibyuma hamwe n’ubushyuhe bwabyo bwiza, bigatanga umusanzu mu iterambere ry’inganda zitandukanye.
