Boron Nitride Phaj

Cov khoom tshwj xeeb ntawm hexagonal boron nitride phaj yog cov thermal conductivity, qis thermal nthuav, siab kub poob siab, siab resistivity, tsis tshua muaj dielectric tsis tu ncua thiab dielectric poob, microwave kis, non-toxic, yooj yim machining, lubrication, tshuaj tsis muaj zog, thiab indistinguishability ntawm feem ntau molten hlau. Cov ntawv hexagonal boron nitride tiv thaiv cov kua qaub thiab hlau ua rau cov hlau tsis haum thiab tuaj yeem ua haujlwm nyob hauv huab cua ntawm 1,000 degrees C (txog 2,000 degrees C hauv qhov chaw ntawm argon lossis nitrogen). Hexagonal boron ceramic nitride nplooj ntawv yog qhov yooj yim rau txheej txheem, kub-resistant mus poob siab, hluav taws xob zoo hluav taws xob thiab zoo heev thermal conductivity. Ntawm kev txaus siab tshwj xeeb yog kub nias boron nitride zoo heev dielectric thaj chaw (dielectric tas mus li 4, uas yog ib nrab ntawm Al2O3), siab dielectric lub zog, thiab zoo lubricity dhau qhov kub ntau. Qhov coefficient tsawg ntawm kev sib txhuam ntawm boron nitride tuaj yeem tswj tau txog 900 degrees C, thaum lub sij hawm uas nyiam cov graphite thiab molybdenum silicone tau raug hlawv. Vim nws qhov kub thiab txias hloov pauv thiab tsis muaj zog rau cov pa roj carbon thiab carbon monoxide txog 1,800 degrees C, nws yog qhov zoo tshaj qhov kub siab xaiv cov khoom siv piv rau cov ntawm silicon nitride, aluminium nitride thiab MgO, CaO, ZrO2. Zoo dua li nws cov khoom tsis-ntub, boron nitride ceramic phaj tiv thaiv cov iav melts, molten silicon, boron, tsis-oxidizing slag, kua ntsev (borax, dej khov muaju) thiab cov hlau ua haujlwm (xws li Al, Fe, Cu, Zn) melts. Vim nws txoj kev ua txhaum tsis zoo, ntom ntom hexagonal boron nitride (HBN) phaj tsuas yog tsim los ntawm kev siv tshuab kub nias.

Cov yam ntxwv kev

Nco tseg: Txawm hais tias peb tsis muaj laj thawj tsis ntseeg tias qhov tseeb ntawm cov ntaub ntawv hais tawm, cov ntaub ntawv no tsuas yog muab rau kev sib piv nkaus xwb. Cov yam ntxwv tseeb yuav sib txawv raws cov qauv tsim khoom thiab cov qauv ua haujlwm, thiab qee zaum yuav raug txiav raws li qhov tshwj xeeb.
