Yuav Ua Li Cas Boron Nitride Yug Thiab Tsim

Boron nitride, tseem hu ua BN, yog cov khoom siv ntau yam thiab muaj txiaj ntsig nrog ntau yam kev siv hauv kev lag luam, hluav taws xob, thiab kev tshawb fawb. Yuav ua li cas boron nitride tuaj mus nrhiav tau thiab tsim rau hauv cov khoom siab heev uas nws niaj hnub no?

Zaj dab neeg ntawm boron nitride pib nyob rau hauv thaum ntxov 19th caug xyoo, thaum Fabkis chemist Joseph-Louis Gay-Lussac thawj synthesized lub compound los ntawm reacting boric acid nrog ammonia gas. Txawm li cas los xij, nws tsis yog txog thaum nruab nrab -20 xyoo pua uas cov kws tshawb fawb tau pib tshawb nrhiav lub peev xwm ntawm boron nitride ua cov khoom siv ua haujlwm siab.

Thaum xyoo 1950 thiab 1960, cov kws tshawb fawb pom tias boron nitride muaj ntau yam khoom muaj txiaj ntsig, suav nrog cov thermal conductivity, hluav taws xob zoo heev, thiab muaj zog tiv thaiv corrosion thiab oxidation. Cov yam ntxwv no tau coj mus rau cov khoom siv hauv ntau hom kev lag luam thiab kev tshawb fawb, xws li cov cuab yeej txiav, tshuab semiconductor, thiab cov khoom siv hauv aerospace.

Tau ntau xyoo tom ntej no, cov kws tshawb fawb txuas ntxiv mus kawm boron nitride thiab tsim cov kev hloov pauv tshiab ntawm cov khoom siv nrog cov khoom sib txawv thiab kev siv. Piv txwv li, hexagonal boron nitride (h-BN) tau pom tias muaj cov khoom siv lubricating tshwj xeeb, ua rau nws muaj txiaj ntsig zoo hauv cov ntawv thov xws li cov roj cav ntxiv thiab cov txheej txheem txheej txheem. Lub caij no, cubic boron nitride (c-BN) tau tsim los ua cov khoom siv zoo tshaj plaws rau kev txiav thiab sib tsoo cov cuab yeej.

Niaj hnub no, boron nitride txuas ntxiv hloov zuj zus thiab nrhiav cov ntawv thov tshiab. Cov kws tshawb fawb tab tom tshawb nrhiav nws lub peev xwm hauv thaj chaw xws li biomedical engineering, photonics, thiab lub zog cia. Ua tsaug rau kev tshawb fawb thiab kev loj hlob tsis tu ncua, boron nitride tseem yog cov khoom tseem ceeb thiab muaj txiaj ntsig nrog lub neej yav tom ntej.

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.
