Mekhoa ea indasteri ea mocheso o phahameng e hloka thepa e ka mamellang mocheso o feteletseng, mafome le ho tšoha ha mocheso ntle le ho beha tšebetso kotsing.Lipoleiti tse hanyetsang tsa silicon carbide (SiC)e hlahella e le tharollo ea boleng bo holimo, e fanang ka ho tšoarella ho sa bapisoeng le ho tenyetseha ho pholletsa le makala a bohlokoa. Ho tloha ho tšepe ho ea ho lisebelisoa tsa elektroniki le tsa letsopa, lipoleiti tsena li bohlokoa ho ntlafatseng bokhoni ba ts'ebetso, ho fokotsa nako ea ho sebetsa, le ho phahamisa boleng ba sehlahisoa—e leng se etsang hore e be tsa bohlokoa bakeng sa tlhahiso ea sejoale-joale ea mocheso o phahameng.
Tšepe ke e 'ngoe ea libaka tsa mantlha tsa ts'ebeliso bakeng sa lipoleiti tse hanyetsang silicon carbide. Ho qhibilihisa aluminium, zinki le koporo, lipoleiti li sebetsa e le li-liners, li-trough, le likarolo tse tšehetsang ka har'a lionto le liphahlo. Ho hanyetsa ha tsona ka mokhoa o ikhethang khoholehong ea tšepe e qhibilihisitsoeng le mocheso o phahameng (ho fihlela ho 1800°C) ho netefatsa bophelo bo bolelele ba ts'ebeletso, ho fokotsa tlhoko ea ho nkeloa sebaka khafetsa. Ho fapana le lisebelisoa tsa setso tse hanyetsang, lipoleiti tsa SiC le tsona li na le conductivity e ntle ea mocheso, li khothaletsa kabo e ts'oanang ea mocheso e ntlafatsang ts'ebetso ea ho qhibiliha ha tšepe le ho fokotsa tšebeliso ea matla ka ho fihlela ho 25%.
Indasteri ea lisebelisoa tsa elektroniki le tsa semiconductor e itšetlehile haholo ka lipoleiti tse hanyetsang tsa silicon carbide bakeng sa lits'ebetso tse nepahetseng tsa mocheso o phahameng. Tlhahisong ea li-semiconductor, li-LED le li-ceramic tsa elektroniki, taolo ea tšilafalo le botsitso ba litekanyo ha li buisanoe. Lipoleiti tse hanyetsang tsa SiC lia ipabola mona, kaha ha li na lik'hemik'hale 'me li boloka sebopeho sa tsona esita le tlas'a potoloho e pheta-phetoang ea ho futhumatsa le ho pholisa. Li sebelisoa haholo ho annealing ea wafer, chemical vapor deposition (CVD), le ho sintering ha likarolo tsa elektroniki, ho thusa bahlahisi ho fokotsa liphoso le ho eketsa sekhahla sa chai haholo.
Lefapheng la lisebelisoa tsa ceramic le tsa bohloeki, lipoleiti tse hanyetsang tsa silicon carbide li fetotse tlhahiso. Ebang ke porcelain e silang, e entsoeng ka majoe, kapa e entsoeng ka letsopa la indasteri, khanyetso e phahameng ea mocheso ea lipoleiti e thibela ho petsoha ho tloha liphetohong tse potlakileng tsa mocheso. Li boetse li hanela ho khomarela ha slag le glaze, li boloka libaka li hloekile ebile li fokotsa nako ea tlhokomelo. Lifeme tsa ceramic tse sebelisang lipoleiti tse hanyetsang tsa SiC li tlaleha bophelo ba ts'ebeletso bo bolelele ba makhetlo a 3-5 ha li bapisoa le lipoleiti tse tloaelehileng, hammoho le ntlafatso ea 10-15% ea sekhahla sa ho tšoaneleha ha sehlahisoa - melemo ea bohlokoa bakeng sa tlhahiso e kholo, e nang le litšenyehelo tse tlase.
Ka nqane ho mafapha ana a mantlha, lipoleiti tsa refractory tsa silicon carbide li fumana lits'ebetso ho matla a nchafatsoang le sefofaneng. Tlhahisong ea betri ea lithium-ion, li tšehetsa ho sintering ha thepa ea cathode mochesong o phahameng, ho netefatsa thepa e tsitsitseng ea thepa. Sefofaneng, li sebelisetsoa ho sinter likarolo tsa ceramic tse sebetsang hantle bakeng sa lienjene le li-avionics. Ka boholo le litlhophiso tse ka fetoloang ho lekana litlhoko tse fapaneng tsa lisebelisoa, lipoleiti tsa refractory tsa SiC li fana ka ts'ebetso e tšepahalang e etselitsoeng litlhoko tse itseng tsa indasteri.
Ho tsetela lipoleiting tse hanyetsang tsa silicon carbide ho bolela ho tsetela bokhabane ba ts'ebetso ea nako e telele. Motsoako oa tsona o ikhethang oa ho hanyetsa mocheso, ho hanyetsa mafome, le ho tsamaisa mocheso li etsa hore e be khetho e theko e tlaase bakeng sa liindasteri tse ikemiselitseng ho ntlafatsa botsitso le tlhahiso. Ntlafatsa lits'ebetso tsa hau tsa mocheso o phahameng kajeno ka lipoleiti tse hanyetsang tsa silicon carbide—moo ho tšoarella ho kopanang le bokhoni, 'me botšepehi bo etsa hore katleho e be teng.
