Pyrolytic Boron Nitride PBN Lihlahisoa
Pyrolytic Boron Nitride (PBN) e entsoe ka mokhoa o tsebahalang oa Chemical Vapor Deposition (CVD) moo khase ea ammonia (NH3) le gaseous boron halide joalo ka boron trichloride(BCI3) li arabelang ka seboping sa mocheso o phahameng oa CVD ho beha. PBN ho substrate e loketseng joalo ka Pyrolytic Graphite.
PBN e tsejoa e le khetho e ntle haholo bakeng sa sebōpi sa mocheso o phahameng le likarolo tsa motlakase, semiconductor, le likristale tsa motsoako oa microwave tse kang germanium(Ge), gallium arsenide(GaAs), le indium phosphate(InP) ka lebaka la bohloeki ba eona ba kahare, thepa e phahameng ea mochine. , le botsitso ba physicochemical. PBN e ka mamella 1800 ° C ka vacuum le 2000 ° C ka nitrogen, e hlahisa e le khetho e ntle bakeng sa likarolo tsa sebōpi le likepe tse qhibilihisang.
Mohaho o nang le lesela la kristale la hexagonal
Thepa e khethehileng ea perpendicular ho sefofane sa basal sa kristale
Botsitso bo phahameng ba sebopeho le physicochemical
Sebopeho sa Anisotropic
Botsitso bo phahameng ba mocheso
E sa kolobiseng
E seng chefo
Li-crucibles bakeng sa kholo ea likristale tsa semiconductor
Wave tubes bakeng sa RF le microwave
Windows e itšetlehileng ka mahlaseli a microwave
Insulator ea motlakase
PBN e nang le thepa e ikhethang le botsitso bo phahameng ba sebopeho le physicochemical e ka ba khetho e ntle ka ho fetisisa joalo ka:
Li-crucibles tsa PBN bakeng sa ts'ebetso ea Vertical Gradient Freezing (VGF).
Li-crucibles tsa PBN bakeng sa ts'ebetso ea Liquid Encapsulation Czochralski (LEC).
Lijana tsa PBN bakeng sa ts'ebetso ea Molecular Beam Epitaxy (MBE).
Likepe tsa PBN bakeng sa li-semiconductors tse kopaneng le ts'ebetso ea alloy
PBN Metal-Organic CVD (MOCVD) mapolanka a ho kenya letsoho le mehele ea MBE
Li-bushings tsa PBN tsa motlakase bakeng sa lisebelisoa tsa vacuum tse phahameng tsa mocheso
PBN travelling wave tube (TWT) e nang le sebopeho sa spiral
