Pyrolytic Boron Nitride Crucibles
Okwu mmalite
Pyrolytic BN ma ọ bụ PBN dị mkpụmkpụ maka pyrolytic boron nitride. Ọ bụ ụdị boron nitride hexagonal nke usoro kemịkalụ vapor deposition (CVD) mepụtara, bụkwa boron nitride dị oke ọcha nke nwere ike iru karịa 99.99%, na-ekpuchi ihe fọrọ nke nta ka ọ bụrụ enweghị porosity.
Nhazi
Dịka akọwara n'elu, pyrolytic boron nitride (PBN) bụ otu n'ime sistemu hexagonal. Oghere intra-layer atomic spacing bụ 1.45 yana oghere atomic interlayer bụ 3.33, nke bụ nnukwu ọdịiche. Usoro nchịkọta maka PBN bụ ababab, na nhazi ya bụ nke ọzọ B na N atom na oyi akwa na n'akụkụ C axis, n'otu n'otu.
Uru
Ihe PBN na-eguzogide oke ujo ma nwee nnukwu anisotropic (na-adabere na ya) njem okpomọkụ. Ọzọkwa, PBN na-eme ihe mkpuchi ọkụ eletrik dị elu. Ihe ahụ kwụsiri ike na inert, na-ebelata, na oxidizing ikuku ruo 2800°C na 850°C, n'otu n'otu.
N'ihe gbasara ngwaahịa, enwere ike ịmepụta PBN ka ọ bụrụ ihe 2D ma ọ bụ 3D dị ka crucibles, ụgbọ mmiri, efere, wafers, tubes, na karama, ma ọ bụ tinye ya dị ka mkpuchi na graphite. Ihe ka ọtụtụ n'ime ọla a wụrụ awụ (Al, Ag, Cu, Ga, Ge, Sn, wdg), acid na amonia na-ekpo ọkụ so na ọnọdụ ebe PBN na-egosipụta nkwụsi ike nke okpomọkụ ma ọ bụrụ na a na-ekpuchi ya na graphite ruo 1700 ° C, na-eguzogide ujo okpomọkụ, ma na-eguzogide ikuku gas.
Ngwaahịa
PBN Crucible: PBN crucible bụ akpa kacha kwesị ekwesị maka imepụta otu kristal semiconductor, na enweghị ike dochie ya;
Na usoro MBE, ọ bụ akpa dị mma maka ikpochapụ ihe na ogige;
Ọzọkwa, a na-eji pyrolytic boron nitride crucible mee ihe dị ka akpa ikuku evaporation na ahịrị mmepụta OLED.
Igwe ọkụ PG/PBN: PBN nwere ike itinye ọkụ gụnyere kpo oku MOCVD, kpo oku igwe, kpo oku evaporation, kpo oku superconductor, kpo oku nyocha nlele, igwe eletrọn microscope sample kpo oku, semiconductor substrate kpo oku, na ihe ndị ọzọ.
Mpempe akwụkwọ/Mgbanaka PBN: PBN nwere ihe pụrụ iche na okpomọkụ dị elu, dị ka ịdị ọcha ya dị elu yana ikike iguzogide ikpo ọkụ ruo 2300 Celsius na oghere dị elu na-enweghị ire ere. E wezụga nke ahụ, ọ anaghị ebufe ihe na-emetọ gas. Ụdị ihe ndị a na-enyekwa ohere ka ịhazi PBN n'ime ụdị geometric dị iche iche.
PBN Coated Graphite: PBN nwere ike ịbụ ihe nnu fluoride dị irè nke, mgbe etinyere ya na graphite, nwere ike ịkwụsị mmekọrịta dị n'etiti ihe ndị ahụ. Ya mere, a na-ejikarị echekwa ihe ndị dị na graphite na igwe.
Ihe PBN n'ime usoro TFPV
Iji ihe PBN n'ime usoro TFPV(ihe nkiri fotovoltaic dị mkpa) na-enyere aka belata ọnụ ahịa nkwụnye ego ma na-abawanye arụmọrụ nke mkpụrụ ndụ PV na-esi na ya pụta, na-eme ka ọkụ eletrik dị ọnụ ala iji mepụta dị ka ụzọ dabere carbon.
Mmechi
Ọtụtụ ụlọ ọrụ na-ahụta ojiji dị ukwuu maka pyrolytic boron nitride. Enwere ike ịsị na ojiji a na-ejikarị ya eme ihe bụ ụfọdụ n'ime àgwà ya dị egwu, gụnyere ezigbo ịdị ọcha na nguzogide corrosion. A ka na-amụ gbasara ngwa pyrolytic boron nitride n'ụdị dị iche iche.
