I-Pyrolytic Boron Nitride Crucibles

Intshayelelo

I-Pyrolytic BN okanye i-PBN imfutshane kwi-pyrolytic boron nitride. Ludidi lwe-boron nitride enehexagonal eyenziwe yindlela yokubeka umphunga wekhemikhali (CVD), ikwayiboron nitride esulungekileyo kakhulu enokufikelela ngaphezulu kwama-99.99%, egquma phantse kungabikho porosity.

Ulwakhiwo

Njengoko kuchaziwe ngasentla, i-pyrolytic boron nitride (PBN) lilungu le-hexagonal system. Isithuba se-athom yangaphakathi yi-1.45 kunye ne-inter-layer isithuba se-athom yi-3.33, umahluko omkhulu. Indlela yokupakisha ye-PBN yi ababab, kwaye ulwakhiwo lwenziwe ngokutshintshana kweeathom ze-B kunye ne-N kumaleko kunye ne-axis ye-C, ngokulandelelanayo.

Inzuzo

Isixhobo se-PBN sixhathisa ngokugqithisileyo kumothuko we-thermal kwaye sine-anisotropic ephezulu (ixhomekeke ngqo) ukuthuthwa kwe-thermal. Ukongeza, i-PBN yenza i-insulator yombane ephezulu. I-substance izinzile kwi-inert, ukunciphisa, kunye ne-oxidizing atmosphere ukuya kuma-2800°C kunye nama-850°C, ngokulandelelanayo.

Ngokubhekiselele kwimveliso, i-PBN inokuqulunqwa kwizinto ze-2D okanye ze-3D ezifana ne-crucibles, izikebhe, iiplate, ii-wafers, iibhubhu, kunye neebhotile, okanye zingasetyenziswa njengengubo kwi-graphite. Uninzi lwezinyithi ezityhidiweyo (i-Al, i-Ag, i-Cu, i-Ge, i-Sn, njl.), i-asidi, kunye ne-ammonia eshushu ziphakathi kweemeko apho i-PBN ibonisa ukuzinza okukhethekileyo kobushushu xa ifakwe kwi-graphite ukuya kwi-1700 ° C, ixhathisa ukutshatyalaliswa kwe-thermal, kwaye ixhathisa ukubola kwegesi.

Imveliso

I-PBN Crucible: I-PBN crucible sesona sikhongozeli sifanelekileyo sokwenziwa kwe-compound semiconductor single crystals, kwaye ayinakutshintshwa;

Kwinkqubo ye-MBE, sisikhongozeli esifanelekileyo sezinto eziphuphumayo kunye neekhompawundi;

Kwakhona, i-pyrolytic boron nitride crucible isetyenziswa njengesikhongozeli sento ephuphumayo kwimigca yemveliso ye-OLED.

• PG/PBN Heater: Izifudumezi ze-PBN ezinokubakho ziquka ukufudumeza kwe-MOCVD, ukufudumeza kweMetal, ukufudumeza okuba ngumphunga, ukufudumeza kwe-superconductor substrate, uhlalutyo lwesampulu yokufudumeza, iisampulu ye-electron microscope ukufudumeza, ukufudumeza kwe-semiconductor substrate, njalo njalo.

   

• Iphepha le-PBN/Iringi: I-PBN ineempawu ezikhethekileyo kumaqondo obushushu aphezulu, njengokusulungeka kwayo okuphezulu kunye nokwazi ukumelana nokufudumeza ukuya kuma-2300 °C kwisifunxa esingaphezulu-phezulu ngaphandle kokubola. Ngaphandle koko, ayikhuphi izingcolisi zegesi. Ezi ntlobo zeepropati zikwavumela i-PBN ukuba iqhutywe kwiintlobo ezahlukeneyo zejometri.

  
  

• I-PBN Coated Graphite: I-PBN inamandla okuba yinto esebenzayo ye-fluoride yetyuwa emanziswe izinto ezinokuthi, xa zifakwe kwigraphite, zinokunqanda intsebenziswano phakathi kwemathiriyeli. Ngaloo ndlela, isetyenziswa rhoqo ukukhusela amacandelo egraphite koomatshini.

PBN Material kwinkqubo ye-TFPV

Ukusetyenziswa kwemathiriyeli ye-PBN kwinkqubo ye-TFPV(thin film photovoltaic) inceda ukunciphisa iindleko zokubeka kunye nokwandisa ukusebenza kakuhle kweeseli ze-PV ezinesiphumo, ukwenza umbane welanga ube nexabiso eliphantsi ukwenza njengeendlela ezisekelwe kwikhabhoni.

Ukuqukumbela

Amashishini amaninzi afumana ukusetyenziswa okumandla kwi-pyrolytic boron nitride. Ukusetyenziswa kwayo ngokubanzi kunokubalelwa kwezinye zeempawu zayo ezintle, kubandakanya ukucoceka okugqwesileyo kunye nokumelana nomhlwa. Ukusetyenziswa okunokubakho kwe-pyrolytic boron nitride kwiinkalo ezahlukeneyo zisaphononongwa.
