    Boron nitride CAS 10043-11-5 yog dab tsi?

    Boron nitride yog siv lead ua los ntawm nitrogen atoms thiab boron atoms. Cov qauv siv lead ua tau muab faib ua hexagonal boron nitride (HBN), kaw-packed hexagonal boron nitride (WBN) thiab cubic boron nitride. Cov qauv siv lead ua ntawm hexagonal boron nitride muaj cov qauv graphite zoo sib xws, nthuav tawm xoob, lubricated, noo noo-absorbing, lub teeb dawb hmoov, yog li nws tseem hu ua "dawb graphite". Lub expansion coefficient ntawm hexagonal boron nitride yog sib npaug rau quartz, tab sis thermal conductivity yog kaum npaug ntawm quartz. Nws kuj muaj lubricity zoo ntawm qhov kub thiab txias thiab yog ib qho zoo heev kub-kub khoom lubricant nrog muaj zog neutron absorption muaj peev xwm, ruaj khov tshuaj, thiab tshuaj inertness yuav luag tag nrho cov hlau molten. Hexagonal boron nitride yog insoluble hauv dej txias. Thaum dej boils, nws hydrolyzes qeeb heev thiab tsim ib tug me me ntawm boric acid thiab ammonia. Nws tsis hnov ​​​​mob nrog tsis muaj zog acids thiab muaj zog hauv paus ntawm chav tsev kub. Nws yog me ntsis soluble nyob rau hauv kub acid thiab tsuas yog decomposed los ntawm kev kho nrog molten sodium hydroxide thiab poov tshuaj hydroxide. Nws muaj ntau yam corrosion kuj rau ntau yam inorganic acids, alkalis, ntsev tov thiab organic solvents.

    Daim ntawv thov

    1. Boron nitride yog siv los ua cov ntaub ntawv refractory, cov khoom siv hluav taws xob hluav taws xob, thiab tseem siv rau hauv electronics, machinery, aviation thiab lwm yam lag luam.

    2. Boron nitride muaj ntau yam zoo heev thiab yog dav siv nyob rau hauv insulators rau high-voltage thiab high-frequency hluav taws xob thiab plasma arcs, coatings rau tsis siv neeg vuam high-temperature resistant thav ntawv, cov ntaub ntawv rau high-frequency induction furnaces, khoom theem admixtures rau semiconductors , cov khoom siv rau cov atomic reactors, ntim cov ntaub ntawv los tiv thaiv neutron hluav taws xob, radar hloov qhov rais, radar kav hlau txais xov xov xwm thiab foob pob ua ntxaij engine Cheebtsam. Vim nws zoo heev lubricating zog, nws yog siv los ua ib tug high-temperature lubricant thiab demoulding tus neeg sawv cev rau ntau yam qauv. Moulded boron nitride tuaj yeem siv los ua cov khoom kub-resistant crucibles thiab lwm yam khoom. Nws tuaj yeem siv los ua cov khoom siv superhard, haum rau kev tshawb nrhiav geological, roj drilling laum cov khoom thiab cov cuab yeej siv ceev ceev. Nws kuj tseem tuaj yeem siv los ua cov khoom siv hlau sib tsoo, nrog rau cov yam ntxwv ntawm qhov ua haujlwm qis ntawm qhov kub thiab qhov tsis zoo ntawm cov khoom. Boron nitride kuj tseem siv tau los ua ib qho ntxiv rau ntau yam ntaub ntawv. Boron nitride fiber ua los ntawm boron nitride yog nruab nrab-modulus high-functional fiber. Nws yog cov khoom siv hluavtaws hluavtaws uas tuaj yeem siv dav hauv kev lag luam tshuaj, kev lag luam textile, aerospace technology thiab lwm yam kev lag luam kev lag luam.

    3.Tshwj xeeb tus neeg sawv cev rau hlau sib sau thiab roj nplua nyeem rau hlau hlau kos duab; tshwj xeeb electrolytic thiab kuj cov ntaub ntawv nyob rau hauv high kub; khoom lubricant; Thaum tshav kub kub foob desiccant rau transistors thiab additive rau polymers xws li yas resins; boron nitride cov khoom uas nias rau hauv ntau yam duab yuav siv tau raws li qhov kub thiab txias, siab siab, rwb thaiv tsev thiab tshav kub dissipation Cheebtsam; thermal shielding cov ntaub ntawv hauv kev lag luam aerospace; nrog kev koom tes ntawm cov catalysts, nws tuaj yeem hloov mus rau hauv cubic boron nitride nyuaj li pob zeb diamond tom qab kub kub thiab kev kho mob siab.
