Thepa le mekhoa ea sintering eali-tubes tsa silicon carbide sebōpilia hlahisoa. Silicon carbide furnace tube ha e na feela litšobotsi tsa matla a mocheso o phahameng le khanyetso ea creep. Ho hanyetsa ho roala, matla a mocheso oa kamore, coefficient e tlase ea likhohlano, ho hanyetsa kutu. E ka sebetsa ka mocheso oa 1600 mme e tsejoa hore e na le khanyetso ea oxidation ka thepa. Silicon carbide furnace tube e na le bofokoli ba bofokoli bo phahameng le boima bo tlase ba fracture. Ka tlhahiso ea morao-rao, ho tiea le matla ho ka ntlafatsoa ka ho eketsa fiber, whisker le particle.
Silicon carbide ke ntho e ntle haholo e thibelang kutu, re ka e sebelisa ho etsa li-tubes tsa sebōpi le lihlahisoa tse ling. Ha silicon carbide e sebelisoa ho etsa li-tubes tsa sebōpi, ho na le mekhoa e sa tšoaneng ea ho chesa e kang ho chesa ho fokolang, mocheso o phahameng, tlhahiso e koetsoeng, e ka khethoang ho ea ka tikoloho ea sebele ea ho sebetsa ho ntlafatsa katleho. Ho hatella ho chesang le mocheso o phahameng oa isostatic ho ka hlahisa letsoalo le phahamengtube ea silicon carbide sebōpi, mocheso oa sintering o pakeng tsa 150 ~ 2100℃. Silicon carbide e thata ho etsa libopeho tse rarahaneng le lihlahisoa tse theko e phahameng. Silicon carbide reaction sintering ke silicon le phofo ea graphite ka karolo e itseng ea botala bo futhumetseng ho hlahisa -SiC. Mokhoa ona o hlahisa silicon carbide e nang le mocheso o tlase oa mollo.

Mabapi le motsamao oa sebōpi sa silicon carbide sebōpi, ka mor'a hore ho hlahisoe tube ea silicon carbide sebōpi, haeba e fetisetsoa ka ntle ho slot ea ts'ebetso, ha se letho ho feta bothata bo kotsi haholo. Botšepehi ba eona bo ka tiisetsoa joang ho tsoa tikolohong e joalo.
