Thepa ea recrystallized silicon carbide
Recrystallized silicon carbide (R-SiC) ke sesebelisoa se sebetsang hantle se nang le boima ba bobeli ho daemane, se entsoeng ka mocheso o phahameng ka holimo ho 2000 ℃. E na le lisebelisoa tse ngata tse ntle tsa SiC, joalo ka matla a mocheso o phahameng, khanyetso e matla ea kutu, khanyetso e ntle ea oxidation, ho hanyetsa mocheso o motle joalo-joalo.
● Mekhoa e metle ea ho sebetsa. Recrystallized silicon carbide e na le matla a phahameng le ho satalla ho feta carbon fiber, khanyetso e matla, e ka bapala ts'ebetso e ntle maemong a mocheso o feteletseng, e ka bapala ts'ebetso e ntle ea ho hanyetsa maemong a fapaneng. Ho phaella moo, e boetse e na le ho feto-fetoha ha maemo hantle 'me ha e senyehe habonolo ka ho otlolla le ho koba, e leng ho ntlafatsang haholo ts'ebetso ea eona.
● Ho hanyetsa ho bola ho hoholo. Recrystallized silicon carbide e na le khanyetso e phahameng ea kutu ho mefuta e fapaneng ea mecha ea litaba, e ka thibela khoholeho ea mefuta e mengata ea mecha ea phatlalatso e senyang, e ka boloka thepa ea eona ea mechine ka nako e telele, e na le ho khomarela ka matla, e le hore e be le bophelo bo bolelele ba tšebeletso. Ho phaella moo, e boetse e na le botsitso bo botle ba mocheso, e ka ikamahanya le mefuta e itseng ea liphetoho tsa mocheso, e ntlafatsa phello ea eona ea kopo.
● Sintering ha e fokotsehe. Hobane ts'ebetso ea sintering ha e fokotsehe, ha ho khatello e setseng e tla baka deformation kapa ho phunyeha ha sehlahisoa, 'me likarolo tse nang le libopeho tse rarahaneng le ho nepahala ho phahameng li ka lokisoa.

VET Energy ke moetsi oa 'nete oa lihlahisoa tse ikhethileng tsa graphite le silicon carbide tse nang le CVD coating, e ka fanang ka likarolo tse fapaneng tse ikhethileng bakeng sa indasteri ea semiconductor le photovoltaic. Sehlopha sa rona sa tekheniki se tsoa litsing tse phahameng tsa lipatlisiso tsa lapeng, se ka u fa litharollo tsa lisebelisoa tse eketsehileng bakeng sa hau.
Re ntse re tsoela pele ho nts'etsapele lits'ebetso tse tsoetseng pele ho fana ka lisebelisoa tse tsoetseng pele, 'me re entse theknoloji e ikhethileng e nang le tokelo ea molao, e ka etsang hore maqhama lipakeng tsa pente le substrate e tiee le hore e se ke ea oela habonolo.
Re u amohela ka mofuthu hore u etele feme ea rona, ha re buisaneng ka ho eketsehileng!
