Pyrolytic Boron Nitride Crucibles

Pyrolytic Boron Nitride Crucibles

Hordhac

Pyrolytic BN ama PBN waa u gaaban boron nitride pyrolytic. Waa nooc ka mid ah boron nitride laba geesood ah oo uu abuuray habka kaydinta uumiga kiimikada (CVD), sidoo kale waa boron nitride aad u saafi ah oo gaari kara in ka badan 99.99%, oo daboolaya ku dhawaad ​​aan lahayn porosity.


Qaab dhismeedka

Sida kor lagu sharaxay, pyrolytic boron nitride (PBN) waa xubin ka mid ah nidaamka laba geesoodka. Kala dheeraynta atomiga-lakabka gudaha waa 1.45 iyo kala dheeraynta lakabka atomiga waa 3.33, taas oo ah farqi weyn. Habka isku dhufashada ee PBN waa ababab, qaabdhismeedkuna waxa uu ka kooban yahay beddelka atomyada B iyo N ee lakabka iyo dhidibka C, siday u kala horreeyaan.


Faa'iidada

Walxaha PBN aad bay ugu adkaysanayaan shoogga kulaylka waxayna leeyihiin gaadiid kuleyl aad u sarreeya (jiho ku tiirsan). Intaa waxaa dheer, PBN waxay samaysaa dahaye koronto oo heersare ah. Walaxdu waxay ku xasiloon tahay jawiga aan shaqaynayn, yaraynta, iyo oksaydhka hawada ilaa 2800°C iyo 850°C, siday u kala horreeyaan.

 

Marka la eego wax soo saarka, PBN waxaa laga yaabaa in loo sameeyo 2D ama 3D walxaha sida crucibles, doomaha, taarikada, maraqa, tuubooyinka, iyo dhalooyinka, ama waxa loo isticmaali karaa sida dahaar si graphite. Inta badan biraha dhalaalay (Al, Ag, Cu, Ga, Ge, Sn, iwm.), aashitada, iyo ammonia kulul ayaa ka mid ah xaaladaha PBN ay muujiso xasilloonida heerkulka aan caadiga ahayn marka lagu dahaadho garaafka ilaa 1700 ° C, waxay u adkaysataa shoogga kulaylka, waxayna u adkaysataa daxalka gaaska.

 

Alaabta

PBN Crucible: Crucible-ka PBN waa weelka ugu habboon ee samaynta isku-darka isku-dhafan ee isku-dhafka ah, lamana beddeli karo;

Habka MBE, waa weelka ugu habboon ee uumi-baxa walxaha iyo iskudhisyada;

Sidoo kale, pyrolytic boron nitride crucible-ka waxaa loo isticmaalaa weel unug ka bixitaan ah oo ku jira khadadka wax soo saarka OLED.

 

  • Kuleyliyaha PG/PBN: Kuleyliyeyaasha PBN ee suurtagalka ah waxaa ka mid ah kuleyliyaha MOCVD, Kuleylinta birta, kuleylinta uumiga, kuleyliyaha substrate-ka sare, kululaynta muunada falanqaynta, kuleylinta muunada mikroskoob ee elektarooniga, kululaynta substrate-ka, iyo wixii la mid ah.

     

  • Sheet/Ring PBN: PBN waxay leedahay sifooyin gaar ah oo heerkul sare ah, sida nadiifnimadeeda sare iyo awood u adkeysiga kulaylka ilaa 2300 °C ee faakuum aad u sarreeya oo aan qudhuneynin. Ka sokow, ma sii daayo sunta gaaska. Noocyada noocaan ah waxay sidoo kale u oggolaanayaan PBN in lagu farsameeyo joomatariyada kala duwan.


  • Garaafyada Dahaarka leh ee PBN: PBN waxa ay awood u leedahay in ay noqoto walxo cusbo leh oo fluoride ah oo wax ku ool ah oo, marka lagu dabaqo garaafka, laga yaabo in ay joojiso isdhexgalka ka dhexeeya alaabta. Sidaa darteed, waxaa badanaa loo isticmaalaa in lagu ilaaliyo qaybaha garaafka ee mashiinnada.


Qalabka PBN ee habka TFPV

Ka faa'iidaysiga walxaha PBN ee habka TFPV(filimka khafiifka ah ee sawirkavoltaic) wuxuu caawiyaa dhimista qiimaha dhigista waxayna kordhisaa waxtarka unugyada PV ee ka soo baxa, taasoo ka dhigaysa korantada qorraxda mid raqiis ah in loo abuuro habab kaarboon ku salaysan.


Gabagabo

Warshado badan ayaa si weyn u isticmaala boron nitride pyrolytic. Isticmaalkeeda baahsan waxaa loo aaneyn karaa qaar ka mid ah sifooyinkeeda cajiibka ah, oo ay ku jiraan nadiifnimo heer sare ah iyo iska caabbinta daxalka. Codsiyada suurtagalka ah ee boron nitride pyrolytic ee dhinacyo kala duwan ayaa wali la daraaseeyaa.
