Pyrolytic Boron Nitride Crucibles
Intangiriro
Pyrolytike BN cyangwa PBN ni ngufi kuri nitride ya pyrolytike. Nubwoko bwa nitride ya borone ya hexagonal yakozwe nuburyo bwo kubika imyuka ya chimique (CVD), nubundi nitride nziza cyane ya boron ishobora kugera kuri 99,99%, bitwikiriye hafi.
Imiterere
Nkuko byasobanuwe haruguru, nitride ya pyrolytike (PBN) ni umunyamuryango wa sisitemu ya mpandeshatu. Umwanya uri hagati ya atome ni 1.45 naho intera hagati ya atome ni 3.33, ni itandukaniro rikomeye. Uburyo bwo gutondekanya kuri PBN ni ababab, kandi imiterere igizwe no guhinduranya atom B na N murwego no kuruhande rwa C axis.
Ibyiza
Ibikoresho bya PBN birwanya cyane ubushyuhe bwumuriro kandi bifite ubwikorezi bwa anisotropique (bushingiye ku cyerekezo). Byongeye kandi, PBN ikora insuliranteri isumba iyindi. Ibintu bihamye muri inert, kugabanya, no guhumeka ikirere kugera kuri 2800 ° C na 850 ° C.
Kubijyanye nibicuruzwa, PBN irashobora kubumbwa mubintu 2D cyangwa 3D nkibibambwa, ubwato, amasahani, wafer, imiyoboro, n'amacupa, cyangwa birashobora gukoreshwa nkigifuniko cya grafite. Ibyinshi mu byuma bishongeshejwe (Al, Ag, Cu, Ga, Ge, Sn, nibindi), aside, na ammonia ishyushye biri mubihe PBN yerekana ubushyuhe budasanzwe iyo ikozwe kuri grafite kugeza kuri 1700 ° C, irwanya ihungabana ryumuriro , kandi irwanya ruswa.
Ibicuruzwa
PBN Crucible: PBN ingirakamaro nikintu gikwiye cyane kugirango habeho ibice bya semiconductor compound, kandi ntibishobora gusimburwa;
Mubikorwa bya MBE, nigikoresho cyiza cyo guhumeka ibintu nibintu;
Nanone, nitride ya pyrolytike boron ikoreshwa nkibikoresho byo guhumeka mumirongo ya OLED.
Ubushyuhe bwa PG / PBN: Ubushyuhe bwa PBN bushobora gukoreshwa harimo gushyushya MOCVD, gushyushya ibyuma, gushyushya ibyuka, gushyushya insimburangingo, gushyushya icyitegererezo, gushyushya icyitegererezo cya elegitoronike, gushyushya semiconductor substrate, nibindi.
Urupapuro rwa PBN / Impeta: PBN ifite ibintu bidasanzwe mubushyuhe bwinshi, nkubuziranenge bwayo nubushobozi bwo kwihanganira ubushyuhe bugera kuri 2300 ° C mu cyuho cyinshi cyane kitangirika. Uretse ibyo, ntabwo isohora ibyuka bihumanya. Ubu bwoko bwimitungo butuma PBN itunganyirizwa muri geometrie zitandukanye.
PBN Yashushanyijeho Graphite: PBN ifite ubushobozi bwo kuba umunyu wa fluor nziza wumunyu wuzuye, iyo ushyizwe kuri grafite, ushobora guhagarika imikoranire hagati yibikoresho. Rero, ikoreshwa kenshi mukurinda ibice bya grafite mumashini.
PBN Ibikoresho mubikorwa bya TFPV
Gukoresha ibikoresho bya PBN muburyo bwa TFPV (thin film Photovoltaic) bifasha kugabanya ikiguzi cyo kubitsa no kongera imikorere yingirabuzimafatizo za PV bivamo, bigatuma amashanyarazi yizuba ahendutse kurema nkuburyo bushingiye kuri karubone.
Umwanzuro
Inganda nyinshi zisanga gukoresha cyane nitride ya pyrolytike. Ikoreshwa ryayo rishobora guterwa na zimwe mu mico itangaje, harimo isuku nziza no kurwanya ruswa. Ibishobora gukoreshwa na pyrolytike boron nitride mubice bitandukanye biracyigwa.
