Boron Nitride Crucible BN Crucible
Tilmaamaha Alaabta
Boron Nitride, oo sidoo kale loo yaqaan BN, Hexagonal Boron Nitride (H-BN), iyo Boron Nitride-kulul, waa dhoobo is-saliim ah oo aad u fiican oo u adkeysan karta heerkulka sare oo ilaalin kara awooddeeda saliidda jawi sare oo faaruq ah.AEM's Boron Nitride crucibles waxaa laga sameeyay boron nitride-kuleyl oo la cadaadiyo maran.Hexagonal Boron Nitride (H-BN) waxay u dhaqmaan si la mid ah graphite si farsamaysan laakiin waxay bixisaa iska caabin koronto oo heer sare ah.
Tilmaamaha ugu muhiimsan
Boron nitride waxay leedahay dahaar koronto oo wanaagsan, kuleyl kuleyl, xasillooni kiimikaad, mana jirto meel dhalaalaysa oo cad.Heerkulka ugu badan ee isticmaalka nitrogen ee 0.1MPA wuxuu gaari karaa 3000 ° C, jawi dhexdhexaad ah oo yareynaya, wuxuu u adkeysan karaa kulaylka ilaa 2000 ° C, heerkulka isticmaalka nitrogen iyo argon wuxuu gaari karaa 2800 ° C, xasilloonida jawiga oksijiinta waa liidata, iyo heerkulka isticmaalka ayaa ka hooseeya 1000 °C.Isku xidhka balaadhinta boron nitride laba geesoodka ah waxay u dhigantaa ta quartz, laakiin kulaylka kuleylku waa toban jeer ka quartz.
Intaa waxaa dheer, boron nitride hexagonal kuma milmo biyo qabow, marka biyaha la kariyo, hydrolysis-ku aad ayuu u gaabiyaa oo soo saaraa qadar yar oo boric acid ah iyo ammonia.Kuma falcelinayso aashito daciif ah iyo saldhig xoog leh heerkulka qolka, wax yar bay ku milmi kartaa aashitada kulul, waxayna u baahan tahay in lagu daaweeyo sodium hydroxide dhalaalaysa iyo potassium hydroxide si ay u qudhunto.

Codsiga Alaabta
Boron nitride waa nooc ka mid ah caabbinta heerkulka sare, iska caabin daxalka, conductivity kaamerada sare, dahaarka sare iyo waxqabadka sifaynta aad u fiican ee walxaha, xaaladda hadda si loo fududeeyo geeddi-socodka, la yareeyo kharashka wax soo saarka, hagaajinta nolosha adeegga qaybaha waa hadda ka firfircoon. jihada cilmi baarista agabka noocaas ah.
(1) Isticmaalka xasiloonida kiimikada ee aadka u wanaagsan ee boron nitride hexagonal, waxaa loo isticmaali karaa sida crucibles, doonyaha, tuubooyinka gudbinta biraha dareere ah, tuubooyinka gantaalaha, saldhigyada qalabka awoodda sare leh, dhuumaha birta dhalaalaysa, qaybaha bamka, caaryada tuurista birta, iwm. dhalaalay biraha uumi baxay.
(2) Isticmaalka kulaylka iyo iska caabinta daxalka boron nitride hexagonal, qaybaha heerkulka sare, dahaarka qolka gubanaya gantaalaha, gaashaan kulaylka hawada hawada sare, magnetocurrent, iwm waa la soo saari karaa.
(3) Isticmaalka dahaarka boron nitride hexagonal, waxaa si ballaaran loo isticmaalaa in koronto-sare-sare-soo noqnoqda sare iyo insulators plasma arc iyo insulators ee kuleyliyaha kala duwan, kulaylinta bushings tuubada iyo heerkulka sare,-soo noqnoqda sare, korantada sare-voltage iyo qaybaha kulaylka, iyo codsiga soo noqnoqda sare ee alaabta foornada korontada.
