Boron nitride CAS 10043-11-5
Boron nitride waa crystal ka kooban atamka nitrogen iyo atamka boron. Qaab dhismeedka crystal wuxuu u qaybsan yahay boron nitride laba geesood ah (HBN), boron nitride laba geesood ah oo ku dhow (WBN) iyo boron nitride cubic. Qaab dhismeedka boron nitride ee laba geesoodka ah wuxuu leeyahay qaab-dhismeedka garaafyada isku midka ah, oo soo bandhigaya dabacsan, dufan, qoyaan nuugaya, budo cad oo khafiif ah, sidaas darteed waxaa sidoo kale loo yaqaan "graphite white". Isku xidhka balaadhinta boron nitride laba geesoodka ah waxay u dhigantaa quartz, laakiin kuleylku waa toban jeer ka quartz. Waxa kale oo ay leedahay subag wanaagsan oo heerkul sare ah waana saliid heerkul sare leh oo aad u fiican oo leh awood nuugista neutronka oo xoogan, sifooyin kiimikaad deggan, iyo dabci kiimikaad ee 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 bay ku milmaysaa aashitada kulul waxaana lagu daaweeyaa oo kaliya sodium hydroxide iyo potassium hydroxide. Waxay leedahay caabbinta daxalka ee kala duwan ee acids inorganic, alkalis, xalalka milixda iyo dareerayaasha organic.

1. Boron nitride waxaa loo isticmaalaa in lagu sameeyo alaabta refractory, alaabta dahaaridda foornada, iyo sidoo kale loo isticmaalo in elektaroonik ah, mishiinada, duulista iyo warshadaha kale.
2. Boron nitride waxay leedahay sifooyin aad u fiican oo si weyn loogu isticmaalo insulators koronto-sare iyo koronto-sare iyo arcs balasmaha, dahaarka alxanka tooska ah ee alxanka heerkul sare, alaabada foornooyinka soo noqnoqda ee soo noqnoqda, isku-darka wejiga adag ee semiconductors Qalabka dhismaha ee reactors atomic, alaabta baakadaha si looga hortago shucaaca neutron, daaqadaha wareejinta radar, warbaahinta anteenada radar iyo qaybaha mishiinka gantaallada. Sababtoo ah sifooyinkeeda saliidda ah ee aadka u fiican, waxaa loo isticmaalaa sidii saliid heerkul sare leh iyo wakiil dumis ah noocyo kala duwan. boron nitride la qaabeeyey ayaa loo isticmaali karaa in lagu sameeyo weelal heerkul sare leh iyo alaabooyin kale. Waxaa loo isticmaali karaa sidii qalab aad u adag, oo ku habboon sahaminta juqraafiyeed, qodista qodista saliidda iyo qalabka goynta xawaaraha sare leh. Waxa kale oo loo isticmaali karaa sida wax lagu shiidi karo processing biraha ah, oo leh sifooyinka heerkulka sare processing hoose iyo cillado dusha dhowr qaybood. Boron nitride sidoo kale waxaa loo isticmaali karaa wax lagu daro walxo kala duwan. Fiber nitride boron oo laga sameeyay boron nitride waa fiber dhexdhexaad ah oo shaqeynaya. Waa shey injineernimada synthetic-ga ah oo si weyn loogu isticmaali karo warshadaha kiimikada, warshadaha dharka, tignoolajiyada hawada sare iyo qaybaha kale ee warshadaha.
3.Wakiilka sii daaya ee samaynta birta iyo saliidaynta sawirida fiilada birta; qalabka elektarooniga ah ee gaarka ah iyo walxaha iska caabinta heerkulka sare; saliid adag; Qalajiyaha kulaylka ee transistor-ka iyo wax lagu daro polymers sida xabagta caagga ah; Badeecadaha boron nitride ee lagu cadaadiyo qaabab kala duwan ayaa loo isticmaali karaa heerkul sare, cadaadis sare, dahaarka iyo qaybaha kulaylka; Agabka kulaylka ee warshadaha hawada; Ka qayb qaadashada kicinta, waxaa loo rogi karaa boron nitride cubic ah oo adag sida dheeman ka dib heerkulka sare iyo daaweynta cadaadiska sare.
