Boron Nitride Crucible BN Crucible
Product Instruction
Boron Nitride, inozivikanwawo seBN, Hexagonal Boron Nitride (H-BN), uye inopisa-yakadzvanywa Boron Nitride, yakanakisa self-lubricate ceramic iyo inogona kumira kutonhora kwakanyanya uye kuchengetedza kugona kwayo kwekuzora munzvimbo yakakwira vacuum.AEM's Boron Nitride crucibles inogadzirwa kubva kune inopisa-yakadzvanywa boron nitride isina chinhu.Hexagonal Boron Nitride (H-BN) inoita zvakafanana negraphite mechanika asi inopa yakanakisa yemagetsi kuramba., uye zvakare inogona kugadzirwa seBN yekupedzisira zvigadzirwa zvakanangana necrucible, chikepe, coating, nezvimwe.
Main Features
Boron nitride ine magetsi ekudzivirira zvakanaka, kupisa kwemhepo, kugadzikana kwemakemikari, uye hapana nzvimbo inonyungudika iri pachena.Iyo yakanyanya tembiricha yekushandisa mu 0.1MPA nitrogen inogona kusvika 3000 ° C, munzvimbo isina kwayakarerekera yekudzikisa, inogona kumira kupisa kusvika 2000 ° C, uye tembiricha yekushandisa munitrogen neargon inogona kusvika 2800 ° C, uye kugadzikana mumhepo yeokisijeni hurombo, uye tembiricha yekushandisa iri pasi pe1000 °C.Iyo yekuwedzera coefficient yehexagonal boron nitride yakaenzana neiyo yequartz, asi iyo inopisa inopeta kagumi iyo yequartz.
Mukuwedzera, hexagonal boron nitride haina kunyungudika mumvura inotonhora, uye kana mvura yakabikwa, iyo hydrolysis inononoka uye inobudisa zvishoma boric acid uye ammonia.Iyo haiite neasidhi isina simba uye hwaro hwakasimba pakudziya kwekamuri, kunyungudika zvishoma muasidhi inopisa, uye inoda kurapwa neyakanyungudutswa sodium hydroxide uye potassium hydroxide kuti iparare.

Product Application
Boron nitride imhando yekudzivirira kwekushisa kwepamusoro, corrosion resistance, high thermal conductivity, high insulation uye yakanakisa lubrication performance yezvinhu, mamiriro azvino kuita kurerutsa maitiro, kuderedza mari yekugadzira, kuvandudza hupenyu hwesevhisi yezvikamu ndiyo yazvino inoshanda zvakanyanya. tsvakiridzo yekutungamira kwezvinhu zvakadaro.
(1) Uchishandisa yakanakisa kugadzikana kwekemikari yehexagonal boron nitride, inogona kushandiswa semacrucibles, mabhoti, mvura yesimbi yekuburitsa pombi, rocket nozzles, yakakwirira-simba mudziyo mabhesi, akanyungudutswa esimbi mapaipi, pombi zvikamu, simbi yekukanda molds, nezvimwe. kunyunguduka simbi dzakaputika.
(2) Kushandisa kupisa uye kupisa kwekudzivirira kwehexagonal boron nitride, yakakwirira-tembiricha zvikamu, rocket combustion chamber linings, spacecraft heat nhovo, magnetocurrent jenareta, nezvimwe zvinogona kugadzirwa.
(3) Kushandisa kuvharwa kwehexagonal boron nitride, inoshandiswa zvakanyanya mu-high-voltage high-frequency magetsi uye plasma arc insulators uye insulators yemhando dzakasiyana-siyana dzinopisa, kupisa tube bushings uye yakakwirira-kupisa, high-frequency, high-voltage insulation uye. kupisa kupisa zvikamu, uye yakakwirira-frequency kushandiswa kwezvinhu zvemagetsi echoto.
