Qhov txawv ntawm Boron Nitride Evaporation Nkoj Thiab Tungsten Nkoj

Boron nitride (BN) nkoj thiab tungsten nkoj yog ob qho tib si siv hauv lub tshuab nqus tsev vacuum. Txawm li cas los xij, muaj qee qhov sib txawv tseem ceeb ntawm ob.

Ua ntej, BN nkoj muaj qhov kub siab tshaj plaws ua haujlwm siab txog li 2000 degree, thaum lub nkoj tungsten feem ntau muaj qhov kub siab tshaj plaws ntawm kev khiav hauj lwm ntawm 1600 degree. Qhov no ua rau BN nkoj zoo dua rau kev siv cov evaporation kub.

Lwm qhov sib txawv yog nyob rau hauv lawv cov khoom siv tshuaj. BN nkoj muaj kev tiv thaiv corrosion, oxidation, thiab tshuaj lom neeg feem ntau, ua rau lawv zoo tagnrho rau kev siv cov hlau reactive thiab cov tebchaw. Tungsten nkoj, ntawm qhov tod tes, tuaj yeem ua rau qee yam tshuaj thiab tuaj yeem ua rau oxidation ntawm qhov kub thiab txias.

Tsis tas li ntawd, cov nkoj BN muaj cov thermal conductivity qis dua piv rau cov nkoj tungsten, txhais tau tias lawv cov cua sov tuaj yeem qeeb dua tab sis tswj tau ntau dua. Tungsten tej nkoj nquam, ntawm qhov tod tes, muab cov cua kub ceev thiab zoo dua rau cov ntawv thov uas yuav tsum tau hloov ceev ceev.

Zuag qhia tag nrho, ob lub nkoj BN thiab tungsten nkoj muaj lawv tus kheej qhov zoo thiab kev siv. Xaiv lub nkoj tsim nyog rau koj cov kev xav tau tshwj xeeb evaporation nyob ntawm cov khoom xws li cov khoom evaporated, qhov kub thiab txias, thiab qhov xav tau cua sov.

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.
