Qhov txawv ntawm Molybdenum Boat Thiab Boron Nitride Evaporation Boat
Oct 06, 2023
Molybdenum tej nkoj nquam thiab Boron Nitride (BN) tej nkoj nquam yog ob qho tib si siv nyob rau hauv high-temperature daim ntaub ntawv, tshwj xeeb tshaj yog nyob rau hauv lub tshav pob ntawm thermal evaporation. Thaum ob hom nkoj sib koom ntau qhov sib xws, muaj qee qhov sib txawv tseem ceeb uas txawv ntawm ib leeg.
Ua ntej, molybdenum tej nkoj nquam yog tsim los ntawm cov hlau molybdenum, uas muaj ib tug melting point ntawm 2,620 degree. Cov nkoj feem ntau coated nrog alumina los yog yttria los txhim kho lawv cov oxidation thiab corrosion. Molybdenum nkoj feem ntau nyiam rau lawv cov thermal conductivity thiab siab mechanical zog. Tsis tas li ntawd, lawv tau yooj yim tsim thiab siv tau rau hauv ntau qhov kub thiab txias.
Nyob rau hauv sib piv, BN nkoj yog tsim los ntawm boron nitride, uas yog ib tug hluavtaws compound nrog high thermal conductivity thiab hluav taws xob rwb thaiv tsev. BN nkoj muaj qhov kub siab tshaj plaws ua haujlwm ntawm ib puag ncig 2, 000 degree, uas yog qis dua li cov nkoj molybdenum. Txawm li cas los xij, lawv cov thermal stability thiab tsis kam rau thermal shock yog qhov tshwj xeeb. BN nkoj yog qhov nyiam rau lawv cov tshuaj tsis muaj zog, tsis tshua muaj coefficient ntawm thermal expansion, tsis tshua muaj zog nto, thiab hluav taws xob rwb thaiv tsev siab.
Zuag qhia tag nrho, ob qho tib si molybdenum thiab BN nkoj muaj lawv tus kheej qhov zoo. Molybdenum tej nkoj nquam yog qhov zoo tshaj plaws rau cov ntawv thov kub uas yuav tsum muaj lub zog txhua yam thiab thermal conductivity. BN nkoj, ntawm qhov tod tes, yog qhov zoo tshaj plaws rau cov ntawv thov uas muaj kev ruaj ntseg thermal, tshuaj inertness, thiab qis zog saum npoo yuav tsum tau. Yog li ntawd, nws yog ib qho tseem ceeb uas yuav tau xaiv lub nkoj zoo uas haum rau koj cov kev xav tau ntawm koj daim ntawv thov tshwj xeeb.
Shengyang New Material Co., Ltd. tau cog lus rau kev tsim cov boron nitride thiab boron nitride ua cov khoom, thiab tuaj yeem kho ntau yam boron nitride insulating ceramic qhov chaw raws li cov neeg siv khoom xav tau. Tiv tauj peb yog tias tsim nyog.
