Pyrolytic Boron Nitride PBN Zogulitsa
Pyrolytic Boron Nitride (PBN) imapangidwa ndi njira yodziwika bwino ya Chemical Vapor Deposition (CVD) momwe mpweya wa ammonia (NH3) ndi gaseous boron halide monga boron trichloride(BCI3) zimachita mu ng'anjo yotentha kwambiri ya CVD kuti isungidwe. PBN pagawo loyenera monga Pyrolytic Graphite.
PBN imadziwika kuti ndi yabwino kusankha ng'anjo yotentha kwambiri ndi zida zamagetsi, semiconductor, ndi makristalo a microwave monga germanium(Ge), gallium arsenide(GaAs), ndi indium phosphate(InP) chifukwa cha chiyero chake, makina apamwamba kwambiri. , ndi kukhazikika kwa physicochemical. PBN imatha kupirira 1800 ° C mu vacuum ndi 2000 ° C mu nayitrogeni, ndikuyiyika ngati chisankho chabwino cha zida za ng'anjo ndi ziwiya zosungunuka.
Kapangidwe kamene kali ndi hexagonal crystal lattice
Katundu wapadera perpendicular ndege yoyambira ya kristalo
Kukhazikika kwapamwamba kwapangidwe ndi physicochemical
Anisotropic kapangidwe
Kukhazikika kwamafuta apamwamba
Kusanyowetsa
Zopanda poizoni
Zopangira kukula kwa ma semiconductor makhiristo
Machubu ozungulira a RF ndi ma microwave
Mawindo akuyatsa ma radiation a microwave
Magetsi insulator
PBN yokhala ndi mawonekedwe apadera komanso kukhazikika kwamphamvu komanso kukhazikika kwa thupi kungakhale chisankho chabwino kwambiri monga:
PBN crucibles ya Vertical Gradient Freezing (VGF) ndondomeko
PBN crucibles ya Liquid Encapsulation Czochralski (LEC) ndondomeko
Zotengera za PBN za njira ya Molecular Beam Epitaxy (MBE).
Maboti a PBN opangira ma semiconductors ndi ma alloy processing
PBN Metal-Organic CVD (MOCVD) matabwa otchinjiriza ndi mphete za MBE
PBN magetsi kutchinjiriza bushings kwa mkulu kutentha vacuum zida
PBN travelling wave chubu (TWT) yokhala ndi mawonekedwe ozungulira
