Thepa le ts'ebeliso ea mantlha ea reaction-sintered silicon carbide

Thepa ea silicon carbide ea Reaction-sintered le ts'ebeliso ea mantlha? Silicon carbide e ka boela ea bitsoa carborundum kapa lehlabathe le sa keneleng mollo, ke motsoako o sa tloaelehang, o arotsoe ka silicon carbide e tala le silicon carbide e ntšo tse peli. Na u tseba thepa le ts'ebeliso ea mantlha ea silicon carbide? Kajeno, re tla hlahisa thepa le ts'ebeliso ea mantlha ea silicon carbide.

Reactive sintering silicon carbide ke ts'ebeliso ea lehlabathe la quartz, calcined petroleum coke (kapa coking ea mashala), slag ea patsi (tlhahiso ea silicon carbide e tala e hloka ho eketsa letsoai la lijo) le lisebelisoa tse ling tse tala, ka sebopi sa mocheso oa motlakase se tsoelang pele ho qhibilihisa mocheso o phahameng.

Thepa ea karabelo-sintered silicon carbide:

1. Thermal conductivity le mocheso katoloso coefficient ea silicon carbide. Joalo ka mofuta oa thepa ea refractory, setene sa carbonized se na le khanyetso e ntle ea ho ts'oha. Sena se bonahala haholo-holo ka conductivity ea eona e matla ea mocheso (coefficient ea ho fetisa mocheso) le coefficient e batlang e le tlaase ea ho atolosa mocheso.

2, conductivity ea silicon carbide. Silicon carbide ke thepa ea semiconductor, conductivity ea eona e fapana le mofuta le bongata ba litšila tse kenngoa ka har'a crystallization, 'me khanyetso e bohareng ba 10-2-1012Ω · cm. Har'a tsona, aluminium, naetrojene le boron li na le tšusumetso e kholo ho conductivity ea silicon carbide, 'me conductivity ea silicon carbide e nang le aluminium e eketsehileng e eketseha haholo.

3. Ho hanyetsa ha silicon carbide. Ho hanyetsa ha silicon carbide ho fetoha ha mocheso o fetoha, empa ka har'a mocheso o itseng oa mocheso le litšobotsi tsa mocheso oa mochine oa tšepe li khutlisetsoa morao. Kamano pakeng tsa ho hanyetsa le mocheso oa silicon carbide e rarahane haholoanyane. The conductivity ea reaction-sintered silicon carbide e eketseha ka mocheso o nyolohelang boleng bo itseng, 'me conductivity e fokotseha ha mocheso o phahama hape.

Tšebeliso ea silicon carbide:

1, lisebelisoa tse manganga - haholo-holo tse sebelisetsoang ho etsa lebili la lehlabathe, sandpaper e silang, whetstone, lebili la ho sila, lebili la ho sila le lihlahisoa tsa photovoltaic liseleng tsa photovoltaic, lisele tsa photovoltaic le likarolo tse holimo ho sila, ho sila le ho bentša.

2, lisebelisoa tse phahameng tsa refractory - li ka sebelisoa e le deoxidizer ea indasteri ea metallurgic le lisebelisoa tse hanyetsanang le kutu, ho etsa lisebelisoa tse entsoeng ka sebōpi sa mocheso o phahameng, likarolo tse tsitsitseng, joalo-joalo.

3, li-ceramics tse sebetsang - ha se feela ho fokotsa boholo ba sebōpi, empa hape le ho ntlafatsa boleng ba lihlahisoa tsa sebōpi sa indasteri, ho fokotsa nako ea potoloho, ke lisebelisoa tse sa tobang tse sa tobang bakeng sa sintering ea ceramic, mocheso o tsoelang pele oa li-ceramics tse se nang oxide, tse bonahatsang porcelain e sintered.

4, litšepe tse sa tloaelehang - likhoebo tsa tšepe le tšepe, lebala la concentrator ea indasteri ea metallurgic, li na le ts'ebeliso e itseng.

5, tse ling - tse sebelisetsoang ho etsa sekoaelo sa mahlaseli a mahlaseli a kotsi kapa se omisang mahlaseli a kotsi a silicon carbide hole-infrared radiation.

Silicon carbide ka lebaka la thepa e boreleli ea lik'hemik'hale, mocheso o phahameng oa phetisetso, coefficient e nyane ea ho atolosoa, ho hanyetsa ho roala hantle, ntle le ho roala lisebelisoa tse hanyetsanang, ho na le lisebelisoa tse ling tsa mantlha, joalo ka: ka ts'ebetso e ncha ea silicon carbide powder glue ho centrifugal impeller kapa cylinder body cavity, e ka ntlafatsa ho hanyetsa ho apara le ho eketsa bophelo ba tšebeletso ea 1 ho linako tse 2; E sebelisetsoa ho etsa lisebelisoa tse phahameng tsa refractory, ho hanyetsa mocheso o phahameng oa mocheso, boholo bo fokolang, boima bo bobebe le matla a phahameng, tšireletso ea tikoloho le phello ea ho boloka matla e hlakile. Silicon carbide ea boemo bo tlase (e nang le hoo e ka bang 85% SiC) ke sesebelisoa se setle sa deoxidizing, se ka sebelisoang ho potlakisa sekhahla sa ho etsa tšepe, 'me se thusa ho laola sebopeho le ho ntlafatsa boleng ba tšepe. Ntle le moo, silicon carbide e boetse e sebelisoa ho etsa lisebelisoa tse ngata tsa ho futhumatsa tsa motlakase silicon molybdenum rod.
