Mu nganda, imiyoboro imeze nk' “imitsi y’amaraso” itwara ibintu bikomeye cyane nk’amabuye y’agaciro, ifu y’amakara, n’ibyondo. Uko igihe kigenda gihita, inkuta z’imbere z’imiyoboro isanzwe zoroshye kwangirika no gutobora, bigasaba gusimburwa kenshi kandi bishobora kugira ingaruka ku musaruro bitewe n’amazi ava. Kuri iyi ngingo, ibikoresho byitwa"Umuyoboro urinda kwangirika kwa karubide ya silikoni"Byari bimeze nko gushyira "ikanzu idakingirwa n'amasasu" ku muyoboro, ukaba "umuhanga" mu guhangana n'ibyangiritse by'ibikoresho.
Hari umuntu ushobora kwibaza ati, “silicon carbide” ni iki? Mu by’ukuri, ni ibikoresho bidakora neza byakozwe mu buryo bw’ubukorano bifite imiterere ikomeye cyane. Urugero, urukuta rw’imbere rw’umuyoboro usanzwe rumeze nk’ubutaka butoshye bwa sima, kandi uko ibikoresho binyuramo, bihora “bishwanyaguza” ubutaka; Urukuta rw’imbere rw’imiyoboro ya silikoni carbide rumeze nk’amabuye akomeye asukuye, rufite ubushobozi buke bwo kudakora neza no kwangirika koroheje iyo ibikoresho binyuramo. Iyi miterere ituma ikomera cyane mu kudakora neza kurusha imiyoboro isanzwe y’icyuma n’imiyoboro ya ceramic, kandi iyo ikoreshejwe mu gutwara ibikoresho byangiritse cyane, igihe cyo kuyikoresha gishobora kongerwa inshuro nyinshi.
Ariko, karubide ya silikoni ubwayo irakomera cyane kandi ishobora kuvunika byoroshye iyo ikozwe mu miyoboro. Imiyoboro myinshi irinda kwangirika kwa karubide ya silikoni ihuza ibikoresho bya karubide ya silikoni n'imiyoboro y'icyuma - haba mu gushyira urwego rwa tile ya karubide ya silikoni ku rukuta rw'imbere rw'umuyoboro w'icyuma, cyangwa hakoreshejwe uburyo bwihariye bwo kuvanga ifu ya karubide ya silikoni n'ubudodo, igasiga urukuta rw'imbere rw'umuyoboro kugira ngo habeho urwego rukomeye rudakwangirika. Muri ubu buryo, umuyoboro ufite ubukomere nk'ubw'icyuma, kidapfa kwangirika cyangwa ngo gicike byoroshye, ndetse no kudakwangirika kwa karubide ya silikoni, bihuza imikorere n'uburambe.
Uretse kuba imiyoboro idashira, imiyoboro idashira ya silikoni ifite ibyiza byo kudashira ubushyuhe bwinshi n'ubukonje no kudashira. Ibikoresho bimwe na bimwe byo mu nganda ntibikunze gusa gukurura cyane, ahubwo bishobora no kugira imiterere ya aside cyangwa alkali. Imiyoboro isanzwe yoroshye kwangirika iyo ikozeho igihe kirekire, mu gihe silikoni ifite ubudashira bukomeye kuri aside na alkali; Nubwo ubushyuhe bw'ibikoresho bitwarwa bwahinduka, imikorere yabyo ntabwo izahinduka cyane, kandi uburyo ikoreshwa ni bwinshi cyane, kuva ku bucukuzi bw'amabuye y'agaciro n'ingufu kugeza ku nganda zikora imiti n'ibyuma, aho bigaragara ko ihari.
Ku bigo, gukoresha imiyoboro idashira ya silikoni ntibisimbura gusa ibikoresho bimwe, ahubwo binagabanya inshuro zo gusimbuza imiyoboro, bigabanya ikiguzi cyo kubungabunga igihe kidakora, kandi bigabanya ingaruka mbi z’umutekano ziterwa no gutakaza ibikoresho. Nubwo ishoramari ryayo rya mbere riri hejuru y’iry’imiyoboro isanzwe, mu gihe kirekire, mu by’ukuri ihendutse cyane.
Muri iki gihe, bitewe n’uko ibikoresho biramba kandi birangwa n’umutekano mu nganda, ikoreshwa ry’imiyoboro irinda kwangirika kwa silicon carbide riri kugenda rirushaho kugaragara. Uku kuvugurura imiyoboro bisa nkaho bitagize icyo bitwaye mu by’ukuri bihisha ubuhanga bw’udushya mu nganda, bigatuma inzira yo kuyikora irushaho kuba nziza kandi ihamye - uyu ni umuyoboro urinda kwangirika kwa silicon carbide, "inzobere mu kurinda kwangirika" irinda bucece "imitsi y’amaraso" y’inganda.
