I-Pyrolytic Boron Nitride Crucibles

Isingeniso

I-Pyrolytic BN noma i-PBN imfushane ku-pyrolytic boron nitride. Iwuhlobo lwe-boron nitride eyi-hexagonal edalwe indlela yokubeka umhwamuko wamakhemikhali (CVD), futhi iyi-boron nitride emsulwa kakhulu engafinyelela ngaphezu kuka-99.99%, emboza cishe ukungabi bikho kwe-porosity.

Isakhiwo

Njengoba kuchazwe ngenhla, i-pyrolytic boron nitride (PBN) iyilungu lesistimu ene-hexagonal. Isikhala se-athomu ye-intra-layer singu-1.45 kanti isikhala se-athomu ye-inter-layer singu-3.33, okuwumehluko obalulekile. Indlela yokunqwabelanisa ye-PBN ithi ababab, futhi isakhiwo sakhiwe ama-athomu angu-B no-N ashintshanayo ongqimbeni kanye ne-axis engu-C, ngokulandelana.

Inzuzo

Impahla ye-PBN imelana ngokwedlulele nokushaqeka okushisayo futhi inokuthutha okushisayo okune-anisotropic kakhulu (okuncike inkombandlela). Ukwengeza, i-PBN yenza isivikelo sikagesi esiphezulu. Lo muthi uzinzile ku-inert, ukwehlisa, kanye ne-oxidizing umkhathi kuze kufike ku-2800°C no-850°C, ngokulandelana.

Ngokuphathelene nomkhiqizo, i-PBN ingase yakhelwe ibe yizinto ze-2D noma ze-3D njengezikebhe, izikebhe, amapuleti, ama-wafers, amashubhu, namabhodlela, noma ingasetshenziswa njengesimbozo ku-graphite. Iningi lezinsimbi ezincibilikisiwe (i-Al, Ag, Cu, Ga, Ge, Sn, njll.), i-asidi, ne-ammonia eshisayo ziphakathi kwezimo lapho i-PBN ibonisa ukuzinza okukhethekile kwezinga lokushisa uma imbozwe ku-graphite efika ku-1700°C, imelana nokushaqeka okushisayo, futhi imelana nokugqwala kwegesi.

Umkhiqizo

I-PBN Crucible: I-PBN crucible iyisitsha esifaneleka kakhulu sokwakhiwa kwekristalu eyodwa ye-semiconductor eyodwa, futhi ayikwazi ukushintshwa;

Enqubweni ye-MBE, iyisitsha esifanelekile sezakhi ezihwamukayo nezinhlanganisela;

Futhi, i-pyrolytic boron nitride crucible isetshenziswa njengesiqukathi sesici sokuhwamuka emigqeni yokukhiqiza ye-OLED.

• I-PG/PBN Heater: Izifudumezi ze-PBN ezingaba izinhlelo zokusebenza zifaka ukushisisa kwe-MOCVD, ukushisisa kwe-Metal, ukushisisa okuhwamukayo, ukushisisa kwe-superconductor substrate, ukushisisa kokuhlaziywa kwesampula, ukushisisa kwesampula yesibonakhulu se-electron, ukushisisa kwe-semiconductor substrate, nokunye.

   

• Ishidi/Indandatho ye-PBN: I-PBN inezici ezihlukile emazingeni okushisa aphezulu, njengokuhlanzeka kwayo okuphezulu kanye namandla okumelana nokushisisa kufika ku-2300 °C ku-vacuum ephezulu kakhulu ngaphandle kokubola. Ngaphandle kwalokho, ayikhiphi izinto ezingcolisa igesi. Lezi zinhlobo zezakhiwo futhi zivumela i-PBN ukuthi icutshungulwe ibe yizinhlobonhlobo zamajometri.

  
  

• I-PBN Coated Graphite: I-PBN inamandla okuba into esebenzayo yokumanzisa usawoti we-fluoride, okuthi uma isetshenziswa ku-graphite, imise ukusebenzisana phakathi kwezinto. Ngakho-ke, ngokuvamile isetshenziselwa ukuvikela izingxenye ze-graphite emishinini.

I-PBN Material kunqubo ye-TFPV

Ukusetshenziswa kokubalulekile kwe-PBN kunqubo ye-TFPV(thin film photovoltaic) kusiza ukwehlisa izindleko zokubeka futhi kukhuphule ukusebenza kahle kwamaseli e-PV angumphumela, okwenza ugesi welanga ushibhile ukuze udale njengezindlela ezisekelwe kukhabhoni.

Isiphetho

Izimboni eziningi zithola ukusetshenziswa okukhulu kwe-pyrolytic boron nitride. Ukusetshenziswa kwayo okusabalele kungabangelwa ezinye zezimfanelo zayo ezinhle, okuhlanganisa ukuhlanzeka okuhle kakhulu nokumelana nokugqwala. Ukusetshenziswa okungenzeka kwe-pyrolytic boron nitride emikhakheni ehlukahlukene kusacwaningwa.
