Boron nitride waa crystal ka kooban atamka nitrogen iyo atamka boron. Qaab dhismeedka crystal wuxuu u qaybsan yahay: boron nitride hexagonal (HBN), boron nitride laba geesood leh (WBN) iyo boron nitride cubic, kuwaas oo ay ka mid yihiin boron nitride crystals. , saliidaysan, fududahay in la nuugo qoyaanka, iyo iftiinka miisaanka, sidaas darteed waxaa sidoo kale loo yaqaan "graphite white".

Cufnaanta aragtida waa 2.27g/cm3, cuf-jiidka gaarka ah waa 2.43, iyo adkaanta Mohs waa 2.

boron nitride hexagonal waxay leedahay dahaar koronto oo wanaagsan, kulaylka kuleylka, xasiloonida kiimikada, ma jirto meel dhalaalaysa oo cad, iska caabbinta kulaylka 3000 ℃ ee 0.1MPA nitrogen, iska caabbinta kulaylka ilaa 2000 ℃ jawiga yaraynta dhexdhexaadka ah, nitrogen iyo heerkulka hawlgalka ee argon wuxuu gaari karaa 2800 ℃, iyo xasiloonida jawiga ogsijiinta waa liidata, iyo heerkulka hawlgalka ayaa ka hooseeya 1000 ℃.

Isku xidhka balaadhinta boron nitride laba geesoodka ah waxay u dhigantaa ta quartz, laakiin kulaylka kuleylku waa toban jeer ka quartz. Waxa kale oo ay leedahay saliid wanaagsan heerkulka sare. Waa saliid adag oo heerkul sare leh oo aad u fiican oo leh awood nuugista neutron-ka oo xoogan, sifooyin kiimiko oo deggan, iyo firfircooni la'aan kiimikaad ilaa ku dhawaad ​​dhammaan biraha dhalaalay.

boron nitride hexagonal waa mid aan lagu milmi karin biyo qabow. Marka biyaha la karkariyo, si tartiib tartiib ah ayey u nadiifiyaan waxayna soo saaraan qadar yar oo boric acid ah iyo ammonia. Kuma falcelinayso asiidh daciif ah iyo saldhigyo xooggan heerkulka qolka. Wax yar ayay ku milmaysaa asiidhyada kulul. Isticmaal sodium hydroxide la dhalaaliyay, farsamaynta potassium hydroxide si aad u burburto. Waxay leedahay awood badan oo ka hortagga daxalka si ay u kala duwan yihiin acids inorganic, alkalis, xalalka milixda iyo dareerayaasha organic.

Parameters Boron Nitride

wps7

1. U adkaysiga kulaylka sare: sublimation at 3000 ℃, xooggeedu waa 2 jeer in heerkulka qolka at 1800 ℃, oo ma jabin doono marka la qaboojiyo heerkulka qolka daraasiin jeer 1500 ℃, oo ma jilcin doono 2800 ℃ in gaaska aan shaqayn.

2. Dhaqdhaqaaqa kulaylka sare: Alaabta kuleylku waa 33W / MK Sida birta saafiga ah, waa walxo kuleyl ah oo ku jira qalabka dhoobada ee ka sarreeya 530 ° C.

3. Kordhinta balaadhinta kulaylka hooseeya: Isku-dhafka fidinta ee 2 × 10-6 waa kan labaad ee quraarad quartz ah, taas oo ah tan ugu yar ee dhoobada. Intaa waxaa dheer, waxay leedahay kororka kuleylka sare, sidaas darteed waxay leedahay caabbinta shoogga kulaylka wanaagsan.

4. Guryaha korantada ee ugu fiican: dahaarka heerkul sare oo wanaagsan, 1014Ω-cm at 25 ° C, iyo 103Ω-cm at 2000 ° C. Waa walxo dahaaran heerkul sare oo ka wanaagsan dhoobada, oo leh danab burbursan oo ah 3KV/MV iyo luminta dielectric hoose ee 108HZ. Marka ay tahay 2.5×10-4, joogtaynta dielectric waa 4, waxayna gudbin kartaa mikrowave iyo falaadhaha infrared.

5. Iska caabin daxalka wanaagsan: oo leh biraha guud (birta, naxaasta, aluminium, lead, iwm.), Biraha dhulka dhifka ah, biraha qaaliga ah, qalabka semiconductor (germanium, silicon, potassium arsenide), galaas, dhalaalid cusbada (dhagaxa crystal, fluoride , slag), acids inorganic, alkalis ma falcelin.

6. Isku-dhafka hoose ee is-jiidhka: U waa 0.16, kaas oo aan ku kordhin heerkulka sare. Waxay aad uga adkeysi badan tahay heerkulka sare marka loo eego molybdenum disulfide iyo graphite. Jawiga oksaydhka ah waxa loo isticmaali karaa ilaa 900 °C, faakuumkana waxa la isticmaali karaa ilaa 2000 °C.

7. Nadaafadda sare: waxa ku jira wasakhdiisu waxa ay ka yar tahay 10PPM, waxa ku jira B waxa ay ka badan tahay 43.6%.

8. Machinability: Adayggeeda waa Mohs 2, sidaa darteed waxaa lagu farsamayn karaa qaybo leh saxnaanta sare iyadoo la adeegsanayo hababka guud ee farsamaynta.
