Batho ba bang ba ka ’na ba ipotsa hore na hantle-ntle silicon carbide ke eng? Ha e le hantle, ke thepa e khethehileng ea letsopa e entsoeng ka silicon le carbon, ka tlhaho e jereng gene ea “e tiileng le e tšoarellang”. Bothata ba eona bo phahame haholo, bo latela daemane feela. Ha ho tsamaisoa phofo ea diminerale le thepa ea slurry bophelong ba letsatsi le letsatsi, esita le khohlano e matla ka ho fetisisa ho thata ho e siea matheba holim’a eona. Ho fapana le liphaephe tse tloaelehileng tsa tšepe, li tla tloha li siloa li le tšesaane ’me li phunyeletse. ’Me litšobotsi tsa eona tsa lik’hemik’hale li tsitsitse haholo, ebang ke acid e matla le alkali chemical media kapa slurry e senyang, li ke ke tsa e senya habonolo, li qoba kotsi ea ho bola ha liphaephe le ho lutla ho tsoa motsong.
Ho hanyetsa mocheso o phahameng le hona ke molemo o moholo oa lesela la liphaephe tsa silicon carbide. Tlhahisong ea indasteri, thepa e mengata e hloka ho tsamaisoa libakeng tse nang le mocheso o phahameng. Liphaephe tse tloaelehileng li sekametse ho fetoha le ho tsofala tlas'a ho baka nako e telele mochesong o phahameng, e leng se amang polokeho ea lipalangoang. 'Me lesela la silicon carbide le ka mamella mocheso o phahameng ka mokhoa o tsitsitseng, ebang ke khase ea flue ea mocheso o phahameng kapa thepa e chesang, e ka tsamaisoa hantle ka botsitso bo felletseng.
Ha ho bapisoa le mekhoa ea setso ea tšireletso ea liphaephe, lesela la silicon carbide le lona le na le likarolo tse ling tse se nang matšoenyeho. Sebopeho sa lona se teteaneng, bokaholimo bo boreleli ebile bo bataletse, 'me ha ho bonolo ho leketlisa kapa ho le lekanya ha ho tsamaisoa thepa. E ka fokotsa masalla a thepa le ho thibana, 'me ea boloka bokhoni ba ho tsamaisa bo tsitsitse. Ka nako e ts'oanang, boima ba eona bo tlase haholo ho feta ba tšepe, 'me lesela la phaephe le ke ke la eketsa boima ka kakaretso haholo. Ebang ke ho kenngoa kapa tlhokomelo ea morao-rao, ho bonolo haholoanyane 'me ho ka boela ha fokotsa mojaro oa ho kenngoa ha liphaephe, ho ikamahanya le maemo a rarahaneng a indasteri.
Ho bohlokoa ho bolela hore ho se sebetse hantle ha lik'hemik'hale tsa silicon carbide ka boeona ho e thibela ho arabela le thepa e tsamaisoang. Esita le bakeng sa thepa e nang le litlhoko tse phahameng tsa bohloeki, ha ho hlokahale hore u tšoenyehe ka tšilafalo e bakoang ke ho kopanya thepa ea lesela. Ebang ke thepa e tala e ntle indastering ea lik'hemik'hale kapa phofo e hloekileng haholo indastering e ncha ea matla, li ka tsamaisoa ka kholiseho. Lena hape ke lebaka la bohlokoa leo ka lona masimo a mangata a indasteri a maemo a holimo a ikemiselitseng ho e khetha.
Matsatsing ana, lesela la liphaephe tsa silicon carbide le fetohile "setsebi se sireletsang" lefapheng la lipalangoang tsa indasteri, ho tloha ho lipalangoang tsa thepa e mahoashe merafong le matla a mocheso ho isa ho lipalangoang tse mahareng tse ntle lik'hemik'hale le libeteri tsa lithium, boteng ba eona bo ka bonoa. E sebelisa ts'ebetso ea eona e ntle ho thusa likhoebo ho fokotsa makhetlo a tlhokomelo ea liphaephe, ho eketsa bophelo ba ts'ebeletso ea lisebelisoa, le ho etsa hore lipalangoang tsa indasteri li sebetse hantle le ho bolokeha haholoanyane.
Jwalo ka litsebi tse ikgethileng lefapheng la diseramiki tsa diindasteri tsa silicon carbide, re ntse re ntlafatsa boleng ba diphaephe tsa silicon carbide, re sebedisa dihlahiswa tse fihlelang ditlhoko tsa diindasteri hamolemo ho netefatsa tlhahiso e tsitsitseng diindastering tse fapaneng. E re lera lena la "diaparo tse thata tse sireletsang" le sireletse "mohala wa pholoso" wa dipalangwang tsa diindasteri tse ngata.
