Sebakeng sa tlhahiso ea indasteri, lisebelisoa tsa ceramic li ngola tšōmo e ncha. Ho fapana le likepe tsa letsopa bophelong ba letsatsi le letsatsi, lirafshoa tsa liindasteri li bonts'itse ts'ebetso ea tsona e ikhethang mafapheng a bohlokoa joalo ka metallurgy, boenjiniere ba lik'hemik'hale le matla a macha. Aluminium oxide, silicon nitride, zirconium oxide le lisebelisoa tse ling li na le litšobotsi tsa tsona, empa ha ho tluoa tabeng ea matla a matla ka ho fetisisa a "sebapali se pota-potileng",li-ceramics tsa silicon carbideha ho pelaelo hore tse molemo ka ho fetisisa.
Li-ceramics tsa aluminium li tšoana le litsebi tsa mesebetsi ea matsoho, tse tsejoang ka ho thatafala ha tsona le ho khoneha, empa li atisa ho sithabetsoa ke mocheso o phahameng. Li-ceramics tsa silicon nitride, joalo ka lisebelisoa tse nepahetseng, li na le khanyetso e ntle ea mocheso, empa li ka bonts'a "likhopo tse bonolo" libakeng tse itseng tse senyang. Li-ceramics tsa Zirconia li tšoana le masole a khethehileng, a tsejoang ka ho ba thata haholo, empa a ka "tloha" mathoasong a mocheso o phahameng le lintoa tse telele.
Ka lehlakoreng le leng, lirafshoa tsa silicon carbide li bonts'itse matla a felletseng a makatsang. Sesebelisoa sena sa kristale, se hahelletsoeng ka thata ka liathomo tsa silicon carbon, ka tlhaho se na le melemo e meraro ea mantlha: mocheso oa eona o matla haholo o o boloka o "khutlile" maemong a mocheso o phahameng, ho hanyetsa ha ona ho etsa hore e be "sebete" maemong a thata a ts'ebetso, 'me botsitso ba eona ba lik'hemik'hale bo tšoana le thebe ea tlhaho e sirelletsang, e hanela ho hlaseloa ha mecha ea litaba e fapaneng.
Lefapheng la tsamaiso ea mocheso, mocheso oa mocheso oa li-ceramics tsa silicon carbide ke makhetlo a mararo a tšepe e tloaelehileng. Talenta ena ea tlhaho ea "talenta ea ho senya mocheso" e etsa hore e be khetho e nepahetseng bakeng sa libotlolo tsa mocheso o phahameng le li-semiconductor substrates. Ha e tobane le phephetso ea ho taboha le ho taboha, ho thatafala ha eona holim'a metsi ho latela daemane, ho bonts'a bophelo bo bolelele ba ts'ebeletso maemong a joalo ka mechini ea merafo le lipeipi tsa lipalangoang. Ntho e sa tloaelehang le ho feta ke hore thepa ena e ka boloka 'mala oa eona oa tlhaho esita le libakeng tse senyang tse kang li-acids tse matla, li ikamahanya hantle le litlhoko tse khethehileng tsa thepa ea lik'hemik'hale.
Ka nts'etsopele e matla ea indasteri e ncha ea matla, lirafshoa tsa silicon carbide li bula libaka tse ncha tsa ts'ebeliso. Lefapheng la ho hlahisa matla a photovoltaic, e fetoha thepa e babatsehang ea tšehetso e hanyetsanang le boemo ba leholimo; Moleng oa tlhahiso ea betri ea lithium, e fetotsoe lipoleiti tse sintered tse phahameng haholo. Bokhoni bona ba "ho tšela moeli" bo bakoa ke motsoako oa eona o ikhethang oa ts'ebetso - e khona ho mamella mocheso o tsitsitseng oa 1350 ℃ le ho sebetsa ka botsitso libakeng tse batang haholo tsa -60 ℃.
Joalo ka litsebi tsa tekheniki tse amehang haholo lefapheng la li-ceramics tsa silicon carbide, re tsoela pele ho ntlafatsa libopeho tsa thepa le lits'ebetso tsa sintering, ha re ntse re boloka melemo ea rona ea setso, re lula re ntlafatsa matla a mochini le ho nepahala ha thepa. Ka litekanyetso tse nepahetseng tsa thepa e tala le theknoloji e ncha ea sintering, lihlahisoa tsa rona li ntlafalitse haholo ho ts'epahala tlas'a maemo a thata a ho sebetsa, ho fana ka tiiso e tiileng ea thepa bakeng sa lisebelisoa tsa morao-rao tsa indasteri.
Ho khetha lisebelisoa tsa ceramic tsa indasteri ha e le hantle ho batla ho leka-lekana pakeng tsa ts'ebetso le litšenyehelo. Li-ceramics tsa Silicon carbide, tse nang le melemo ea tsona e ikhethang ea ts'ebetso ea litšenyehelo, li hlalosa bocha litekanyetso tsa tlhahiso ea indasteri - ho fokotsa makhetlo a ho fetola ka nako e telele, ho fokotsa litšenyehelo tsa tlhokomelo ka ts'ebetso e tsitsitseng haholoanyane, le ho nolofatsa khetho ea lisebelisoa ka mefuta e mengata ea likopo. Lena e kanna ea ba lebaka le ka sehloohong le etsang hore baenjiniere ba ntseng ba eketseha ba e thathamise e le thepa e ratoang.
Ha re bua ka tsoelo-pele ea indasteri, tlhahiso ea lintho tse bonahalang hangata ke ntlha ea bohlokoa ka ho fetisisa le ea bohlokoa. Phetoho e tsoelang pele ea li-ceramics tsa silicon carbide ha e bontše feela katleho ea theknoloji ea ceramic, empa e boetse e phatlalatsa katleho e 'ngoe ea katleho ea tlhahiso ea indasteri. Nakong ena ea ho phehella ts'ebetso ea ho qetela, thepa ena ea "monahano" ea ceramic e bula sebaka se secha sa ho nahana bakeng sa tlhahiso ea sejoale-joale.
