Pyrolytic Boron Nitride Crucibles
Hoʻolauna
He pōkole Pyrolytic BN a i ʻole PBN no pyrolytic boron nitride. He ʻano ia o ka boron nitride hexagonal i hana ʻia e ka chemical vapor deposition (CVD).
Kapili
E like me ka mea i wehewehe ʻia ma luna nei, ʻo ka pyrolytic boron nitride (PBN) kekahi lālā o ka ʻōnaehana hexagonal. He 1.45 ka mokowa atomika intra-layer a he 3.33 ka mokowa atomic inter-layer, he ʻokoʻa nui. ʻO ka ʻōnaehana hoʻopaʻa ʻana no ka PBN he ababab, a ua hana ʻia ke ʻano me nā ʻāpana B a me N i hoʻololi ʻia i ka papa a me ke koʻi C, kēlā me kēia.
Pōmaikaʻi
Paʻa loa ka mea PBN i ka haʻalulu wela a loaʻa iā ia kahi halihali wela anisotropic (pili kuhikuhi). Eia kekahi, hana ʻo PBN i kahi insulator uila maikaʻi loa. Paʻa ka mea i loko o ka inert, hōʻemi, a me ka oxidizing ea a hiki i 2800 ° C a me 850 ° C, kēlā me kēia.
Ma ke ʻano o ka huahana, hiki ke hana ʻia ka PBN i mau mea 2D a i ʻole 3D e like me nā crucibles, nā waʻa, nā pā, nā wafers, nā paipu, a me nā ʻōmole, a i ʻole hiki ke hoʻohana ʻia ma ke ʻano he uhi i ka graphite. ʻO ka hapa nui o nā metala i hoʻoheheʻe ʻia (Al, Ag, Cu, Ga, Ge, Sn, a me nā mea ʻē aʻe), ka waikawa, a me ka amonia wela i waena o nā kūlana kahi e hōʻike ai ka PBN i ke kūpaʻa ʻokoʻa o ka mahana ke uhi ʻia ma ka graphite a hiki i 1700°C, pale i ka haʻalulu wela. , a pale aku i ke kinoea.
Huahana
PBN Crucible: ʻO ka PBN crucible ka ipu kūpono loa no ka hoʻokumu ʻana i nā kristal hoʻokahi semiconductor hui, a ʻaʻole hiki ke pani ʻia;
Ma ke kaʻina hana MBE, ʻo ia ka ipu kūpono no ka hoʻoheheʻe ʻana i nā mea a me nā pūhui;
Eia kekahi, hoʻohana ʻia ka pyrolytic boron nitride crucible ma ke ʻano he pahu evaporation element ma nā laina hana OLED.
PG/PBN Heater: PBN nā mea hoʻohana hiki ke hoʻohana ʻia me ka hoʻomehana MOCVD, ka wela metala, ka wela hoʻoheheʻe ʻana, ka hoʻomehana substrate superconductor, ka hoʻoheheʻe ʻana i ka laʻana, ka hoʻoheheʻe ʻana o ka microscope electron, ka wela semiconductor substrate, a pēlā aku.
PBN Pepa/Ring: He mau waiwai kūʻokoʻa ko PBN i nā wela kiʻekiʻe, e like me kona maʻemaʻe kiʻekiʻe a me ka hiki ke kū i ka wela a hiki i 2300 °C i loko o kahi ʻūhā kiʻekiʻe loa me ka ʻole o ka palaho. Ma waho aʻe, ʻaʻole ia e hoʻokuʻu i nā mea haumia kinoea. ʻAe kēia mau ʻano waiwai i ka PBN e hana ʻia i loko o nā ʻano geometries.
PBN Coated Graphite: Hiki i ka PBN ke lilo i mea hoʻomaʻemaʻe i ka paʻakai fluoride maikaʻi, ke hoʻohana ʻia i ka graphite, hiki ke hoʻopau i ka pilina ma waena o nā mea. No laila, hoʻohana pinepine ʻia e pale i nā ʻāpana graphite i nā mīkini.
PBN Material ma ke kaʻina hana TFPV
ʻO ka hoʻohana ʻana i ka mea PBN ma ke kaʻina hana TFPV(thin film photovoltaic) e kōkua i ka hōʻemi ʻana i ke kumukūʻai o ka waiho ʻana a me ka hoʻonui ʻana i ka pono o nā pūnaewele PV hopena, e hoʻolilo i ka uila o ka lā ma ke ʻano he kumu kalapona.
Ka hopena
Nui nā ʻoihana e ʻike i ka hoʻohana nui ʻana no ka pyrolytic boron nitride. Hiki ke hoʻohana ʻia kona hoʻohana nui ʻana i kekahi o kāna mau hiʻohiʻona maikaʻi, me ka hoʻomaʻemaʻe maikaʻi loa a me ka pale ʻana i ka corrosion. Ke aʻo ʻia nei nā noi kūpono o ka pyrolytic boron nitride ma nā ʻano like ʻole.
