Sintering txheej txheem tswv yim rau Boron Nitride Evaporation Boats

Boron Nitride (BN) Evaporation Boat Sintering Technique thiab kev siv

Boron Nitride (BN), tseem hu ua dawb graphite, yog cov khoom siv zoo heev vim nws cov yam ntxwv tshwj xeeb xws li thermal stability, zoo heev hluav taws xob rwb thaiv tsev, thiab siab thermal conductivity. BN muaj ntau yam kev siv, suav nrog cov khoom siv thermal tswj rau cov khoom siv hluav taws xob, cov roj ntsha kub kub, cov pwm tso tawm tus neeg sawv cev, thiab crucibles rau cov hlau yaj.

Cov txheej txheem ntawm sintering BN nyob rau hauv ib lub nkoj evaporation tso cai rau zus tau tej cov BN nyob rau hauv ntau hom, nrog rau cov nplooj ntawv, hmoov, thiab rods. Txhawm rau kom ua tiav qhov kev ua tau zoo, ntau cov txheej txheem yuav tsum tau ua haujlwm thaum lub sijhawm sintering. Ib qho tseem ceeb tshaj plaws yog kev tswj qhov kub thiab txias. BN sintering yuav tsum muaj qhov kub thiab txias ntawm 1700 txog 2200 degree. Qhov kub thiab txias yuav tsum tau tswj xyuas kom meej los tiv thaiv BN los ntawm kev tawg dhau los yog poob nws cov khoom tshwj xeeb.

Lwm qhov tseem ceeb tshaj plaws yog kev tswj hwm huab cua. Cov txheej txheem sintering yuav tsum muaj nyob rau hauv ib qho chaw inert los yog lub tshuab nqus tsev kom tsis txhob muaj kab mob BN. Txhua yam khoom txawv teb chaws tuaj yeem hloov kho cov khoom ntawm BN thiab cuam tshuam nws qhov kev ua tau zoo.

Lub nkoj evaporation nws tus kheej kuj ua lub luag haujlwm tseem ceeb hauv cov txheej txheem sintering. Lub nkoj yuav tsum tau ua los ntawm cov ntaub ntawv uas muaj chemically inert thiab thermally ruaj khov, xws li graphite lossis ceramic. Qhov no ua kom ntseeg tau tias BN tsis muaj kab mob thaum lub sijhawm sintering.

Cov ntawv thov ntawm BN yog qhov loj, thiab cov txheej txheem sintering yog qhov tseem ceeb hauv kev tsim cov khoom siv rau ntau yam kev siv. Piv txwv li, hauv kev lag luam hluav taws xob, BN yog siv los ua lub dab dej kub kom dissipate cua sov uas tsim los ntawm cov khoom siv hluav taws xob siab. Hauv kev lag luam automotive, BN yog siv los ua cov khoom siv hauv cov hlua khi vim nws cov thermal conductivity thiab muaj peev xwm los txo kev sib txhuam. Hauv kev lag luam aerospace, BN yog siv los ua cov khoom siv thermal rwb thaiv tsev los tiv thaiv lub dav hlau rov nkag tsheb los ntawm qhov kub thiab txias.

Hauv kev xaus, cov txheej txheem sintering rau kev tsim BN nyob rau hauv ntau hom yog ib tug complex thiab intricate txheej txheem. Nws yuav tsum muaj kev tswj xyuas qhov kub thiab txias, huab cua, thiab cov khoom siv, nrog rau lub nkoj evaporation. Txawm li cas los xij, cov khoom siv tau muaj ntau yam kev siv hauv ntau qhov kev lag luam, ua kom muaj txiaj ntsig zoo thiab meej ntawm BN qhov tseem ceeb.
