Yuav ua li cas tshem tawm impurities hauv Boron Nitride

Nitride boron, tseem hu ua boron nitride, yog ib qho tseem ceeb ntawm cov khoom siv dav hauv kev lag luam vim nws cov khoom siv zoo heev thiab thermal. Txawm li cas los xij, impurities yuav muaj nyob rau hauv nitride boron thaum lub sij hawm fabrication thiab ntau lawm txheej txheem. Txhawm rau kom ntseeg tau qhov zoo ntawm nitride boron, nws yog ib qho tsim nyog los tshem tawm cov impurities. Nov yog qee txoj hauv kev ua li ntawd.

Ua ntej, lim dej yog ib txoj hauv kev siv los tshem tawm impurities. Cov nitride boron tuaj yeem dhau los ntawm lub lim nrog qee qhov pore loj los lim tawm cov impurities loj dua. Txoj kev no yog qhov yooj yim, ua tau zoo, thiab tuaj yeem tshem tawm impurities zoo.

Qhov thib ob, kev ntxuav yog lwm txoj hauv kev los tshem tawm impurities. Cov nitride boron tuaj yeem ntxuav nrog tshuaj lom neeg kom yaj thiab tshem tawm impurities. Kev xaiv cov tshuaj tov yog nyob ntawm hom impurities. Piv txwv li, hydrofluoric acid tuaj yeem siv los ua kom cov txhuas tsis huv hauv nitride boron. Txoj kev no zoo rau kev tshem tawm cov impurities, tab sis nws yuav tsum muaj cov cuab yeej tshwj xeeb thiab kev txawj ntse kom tsis txhob ua rau cov nitride boron puas.

Thaum kawg, annealing yog ib txoj kev uas tsim nyog rau tshem tawm impurities uas muaj siab vapor siab. Cov nitride boron tuaj yeem muab tso rau ntawm qhov kub siab hauv qhov chaw nqus tsev kom vaporize cov impurities. Txoj kev no muaj txiaj ntsig zoo rau kev tshem tawm cov impurities tsis haum, tab sis nws kuj tseem tuaj yeem ua rau muaj kev puas tsuaj rau nitride boron yog tias qhov ntsuas kub tsis tswj tau zoo.

Hauv kev xaus, kev tshem tawm cov impurities hauv nitride boron yog qhov tseem ceeb los xyuas kom meej tias nws zoo nyob rau hauv cov ntawv thov kev lag luam. Cov txheej txheem hais saum toj no, xws li lim, ntxuav, thiab annealing, yog siv tau zoo thiab dav siv. Nrog rau cov cuab yeej tsim nyog thiab kev txawj ntse, impurities tuaj yeem raug tshem tawm tau zoo, thiab cov khoom zoo nitride boron tuaj yeem tau txais.

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.
