Likarolo tsa ceramic bakeng sa bohloeki bo phahameng ba silicon nitride semiconductors

Tlhaloso e Khutšoanyane:

Silicon nitride e na le khanyetso e ntle ea mocheso ho feta lirafshoa tse ling. E kopantsoe le matla a phahameng, katoloso e tlase ea mocheso, ho hanyetsa kutu e ntle le ho tiea ha fracture, silicon nitride e atisa ho sebelisoa indastering ea lifofane kapa ea likoloi. Lisebelisoa tse ling tse kang li-nozzles tsa mollo, ts'ebetso ea tšepe e entsoeng ka tšepe e qhibilihisitsoeng, joalo-joalo. Insulation ea motlakase, ho hanyetsa kutu e ntle, mocheso o sebetsang o mahareng (13000C), lirafshoa tsa moralo, thepa e ntle ea mochini, katoloso e tlase ea mocheso, conductivity e phahameng ea mocheso, botsitso bo botle ba mocheso, botsitso bo tlase ba mocheso. matla a khoheli.

Silicon nitride ke ceramic e bohlooho e nang le bothata bo phahameng ba ho robeha, ho hanyetsa mocheso o matla haholo, le thepa e batlang e sa kenellehe ho litšepe tse qhibilihisitsoeng.

U sebelisa litšoaneleho tsena, e sebelisoa ho likarolo tsa enjene e tukang ka hare joalo ka likarolo tsa enjene ea koloi, li-nozzles tsa mochini oa welding blowpipe, joalo-joalo, haholo likarolo tse hlokang ho sebelisoa libakeng tse thata joalo ka ho futhumatsa.

Ka khanyetso ea eona e phahameng ea ho roala le matla a phahameng a mochini, lits'ebetso tsa eona ho roala likarolo, li-bearings tse potolohang tsa shaft le lisebelisoa tsa tlhahiso ea semiconductor li ntse li eketseha.

Thepa ea silicon nitride ceramics

1, e na le matla a phahameng sebakeng se seholo sa mocheso;

2, phahameng fracture toughness;

3, matla a ho koba a matle;

4, ho hanyetsa mokhathala oa mochine le ho fofa;

5, khanya - tlaase segokanyipalo;

6, boima bo phahameng le ho apara ho hanyetsa;

7, ho hanyetsa mocheso o babatsehang oa mocheso;

8, katoloso e tlase ea mocheso;

9, insulator ea motlakase;

10, khanyetso e ntle ea oxidation;

11, khanyetso e ntle ea kutu ea lik'hemik'hale.

Li-ceramics tsa silicon nitride li na le coefficient e tlase ea katoloso ea mocheso le conductivity e phahameng ea mocheso, kahoo li na le khanyetso e ntle ea mocheso. Silicon nitride e hatelitsoeng ka mocheso o chesang e ke ke ea robeha ka mor'a ho futhumatsoa ho 1000 ℃ ebe e kenngoa ka metsing a batang. Ha mocheso o sa phahame haholo, silicon nitride e na le matla a phahameng le ho hanyetsa tšusumetso, empa ka holimo ho 1200 ℃ e tla senyeha ka kholo ea nako ea tšebeliso, e le hore matla a eona a fokotsehe, a kotsing ea ho senyeha ha mokhathala ka holimo ho 1450 ℃, kahoo tšebeliso ea eona e fokotsehile. mocheso oa Si3N4 ka kakaretso ha o fete 1300 ℃.
