Gushira no kwangirika ni ikibazo kidasubirwaho mu musaruro w’inganda no mu buzima bwa buri munsi. Kuva ku kwangirika kw’ibice mu gihe cy’ikoreshwa ry’imashini kugeza ku kuzura no gusukura ku nyubako, gusaza no kwangirika ntibigabanya gusa igihe cyo gukora ibikoresho, ahubwo bishobora no kongera ikiguzi cyo kubungabunga no kugira ingaruka ku musaruro. Mu bikoresho byinshi birwanya kwangirika no kwangirika, silicon carbide yabaye "igikoresho gikomeye" gikunzwe cyane kubera ko kidashira neza, kirinda bucece imikorere ihamye y’ibice bitandukanye.
Impamvukarubide ya silikoniishobora kuba "umwami udashira" ishingiye ku miterere yayo yihariye ya kristu. Ni ikintu kigizwe n'ibintu bibiri, silicon na karuboni, bifatanye neza n'imigozi ya covalent. Imbaraga zikomeye z'iyi migozi y'ubu bufatanye bw'ibinyabutabire zituma kristu za kristu za karuboni zikomera cyane - zikaba iza kabiri nyuma ya diyama na nitride ya boroni ya cubic, iruta cyane ibyuma bisanzwe n'ibikoresho byinshi bya ceramic. Imiterere ya kristu ikomeye imeze nk'"uruzitiro karemano", rugoye kwangiza imiterere y'imbere ya kristu za karuboni iyo ibintu byo hanze bigerageje gukurura cyangwa gukurura ubuso, bikarinda kwangirika no kwangirika.
Uretse kuba ifite ubukana, uburyo silicon carbide ihagaze neza mu buryo bw’imiti yongera ubushobozi bwayo bwo kudashira. Ntabwo ikunze kugira ingaruka mbi ku binyabutabire mu bidukikije nk’ubushyuhe bwinshi n’ubushyuhe bwinshi, kandi ntabwo izangiza imiterere y’ubuso bitewe n’ubushyuhe cyangwa ingese, bityo igakomeza kudashira neza. Byaba ari ibikoresho birwanya ubushyuhe mu matanura ashyushye cyane cyangwa amasafuriya adashobora gusaza mu mashini zicukura amabuye y’agaciro, silicon carbide ishobora kuguma mu mwanya wayo mu bidukikije bigoye kandi ikagabanya igihombo giterwa no gusaza no kwangirika.
Abantu benshi bashobora kuba batazi silicon carbide, ariko yamaze kwinjira mu buzima bwacu bwose. Mu rwego rw'ubwubatsi, hasi idashira hamwe na silicon carbide yongewemo ishobora kwihanganira gukandagirwa kenshi n'imodoka no kugenda n'abakozi, bigatuma ubutaka buhora bumeze neza kandi bugororotse igihe kirekire; Mu nganda zikora imashini, ibikoresho byo gukata n'amapine yo gusya akozwe muri silicon carbide bishobora gukata no gusya byoroshye ibikoresho bikomeye by'icyuma bidashira cyane; Ndetse no mu rwego rw'ingufu nshya, ibyuma bya silicon carbide ceramic bearings, bifite imiterere idashira, bifasha ibikoresho kugera ku musaruro mwiza no kuramba.
Kubera ko ari ibikoresho byiza cyane bidashira, silicon carbide ntigaragaza gusa ubwiza bw'ubumenyi bw'ibikoresho, ahubwo inagira uruhare runini mu guteza imbere iterambere ry'inganda no kugabanya ikoreshwa ry'ingufu. Bitewe n'iterambere rihoraho ry'ikoranabuhanga, uburyo bwo gukoresha silicon carbide buracyari kwiyongera. Mu gihe kizaza, uyu "mwami udashira" azazana garanti zirambye kandi zizewe ku nzego nyinshi, agaragaza imbaraga z'ibikoresho zo "kwihangana" hamwe n'imbaraga.
