(1) Indasteri e holimo
Silicon carbide powder le tšepe ea silicon phofo ke lisebelisoa tse tala tse hlokoang ke indasteri. Tlhahiso ea silicon carbide ea Chaena e qalile lilemong tsa bo-1970. Ka mor'a lilemo tse fetang 40 tsa tsoelo-pele, indasteri e fihlile hōle haholo. Theknoloji ea ho qhibilihisa, lisebelisoa tsa tlhahiso le lipontšo tsa tšebeliso ea matla li fihlile boemong bo botle. Hoo e ka bang 90% ea silicon carbide lefatšeng e hlahisoa Chaena. Lilemong tsa morao tjena, theko ea silicon carbide phofo ha ea fetoha haholo; Metal silicon phofo e hlahisoa haholo Yunnan, Guizhou, Sichuan le libakeng tse ling tse ka boroa-bophirima. Ha metsi le motlakase li le ngata hlabula, theko ea phofo ea silicon ea tšepe e batla e le theko e tlaase, ha mariha, theko e phahame hanyenyane ebile e fetoha, empa ka kakaretso e tsitsitse. Liphetoho tsa litheko tsa thepa e tala indastering e kaholimo ho naha li na le tšusumetso e itseng melaong ea litheko tsa lihlahisoa le maemo a litšenyehelo a likhoebo indastering.
(2) indasteri e tlaase
Karolo e ka tlase ea indasteri ke indasteri ea kopo ea sehlahisoa sa silicon carbide ceramic. Lihlahisoa tsa silicon carbide ceramic ha li fapane feela, empa hape le ts'ebetso e ntle haholo. E sebelisoa haholo kahong, li-ceramics tsa bohloeki, lirafshoa tsa letsatsi le letsatsi, lisebelisoa tsa makenete, likhalase-ceramics, libopi tsa indasteri, likoloi, lipompo, liboilers, liteishene tsa motlakase, ts'ireletso ea tikoloho, ho etsa pampiri, peterole, metallurgy, indasteri ea lik'hemik'hale, mechini, sefofane le likarolo tse ling. Ka ts'ebetso e phahameng ea lihlahisoa tsa silicon carbide ceramic e 'nile ea hlokomeloa ke liindasteri tse ngata, mefuta e mengata ea tšebeliso ea lihlahisoa tsa silicon carbide ceramic e tla ba bophara le ho feta. Tsoelopele e phetseng hantle, e tsitsitseng le e potlakileng ea indasteri e tlase e tla fana ka sebaka se pharaletseng sa mmaraka bakeng sa indasteri le ho khothaletsa nts'etsopele e hlophisehileng ea indasteri eohle.
Ka ts'ebeliso e pharalletseng ea lihlahisoa tsa sepakapaka tsa sintered silicon carbide ceramic, tlhokahalo ea mmaraka le eona e ntse e eketseha, e hohela karolo e kholo ea motse-moholo tšimong ea tlhahiso ea silicon carbide ceramic. Ka lehlakoreng le leng, tekanyo ea indasteri ea silicon carbide e ntse e eketseha, 'me tlhahiso ea pele ea libaka e hasanngoa likarolong tsohle tsa naha. Ka nako e khuts'oane ea lilemo tse leshome, indasteri ea silicon carbide e tsoetse pele ka potlako. Ka lehlakoreng le leng, ha tekanyo ea indasteri e ntse e tsoela pele ho hola, e boetse e tobane le ketsahalo ea tlhōlisano e sehlōhō. Ka lebaka la moeli o tlase oa ho kena indastering, palo ea likhoebo tsa tlhahiso e kholo, boholo ba likhoebo bo fapane, 'me boleng ba sehlahisoa ha bo lekane.
Likhoebo tse ling tse kholo li shebana le ntlafatso ea theknoloji le lipatlisiso le nts'etsopele ea lihlahisoa tse ncha; Sekala se ntse se tsoela pele ho hola, 'me ponahalo le tšusumetso ea k'hamphani li ntse li eketseha letsatsi le letsatsi. Ka nako e ts'oanang, bahlahisi ba banyenyane ba ntseng ba eketseha ba ka itšetleha feela ka leano la theko e tlaase ho nka litaelo, e leng se lebisang tlhōlisanong e mpe indastering. Tlhōlisano ea indasteri e bohale, 'me indasteri e tla boela e bontše mokhoa oa polarization.
