Kuyera kwakukulu kwa hexagonal boron nitride ufa cas 10043-11-5 Boron nitride (BN 99%)
Boron nitride imapangidwa ndi nayitrogeni ndi maatomu a boron mu kristalo, mawonekedwe a kristalo amatha kugawidwa kukhala: hexagonal boron nitride (HBN), mizere yowongoka ya hexagonal boron nitride ndi kiyubiki boron nitride, mawonekedwe akristalo a hexagonal boron nitride ali ndi ma graphite ofanana. mawonekedwe osanjikiza, otayirira, opaka mafuta, kuyamwa mosavuta kwa chinyezi, kuwala ndi mawonekedwe ena a ufa woyera, nenaninso "graphite yoyera.
Hexagonal boron nitride ili ndi kutchinjiriza kwamagetsi kwabwino, kukhazikika kwamafuta, kukhazikika kwamankhwala, palibe malo osungunuka, kutenthetsa mpaka 3000 ℃ mu nayitrogeni 0.1 MPA, m'malo ochepetsera ndale, kupirira kutentha mpaka 2000 ℃, nayitrogeni ndi argon amagwiritsidwa ntchito. mu kutentha akhoza kufika 2800 ℃, osauka bata mu mpweya mpweya, kutentha m'munsimu 1000 ℃.Kukula kokwanira kwa boron nitride ndikofanana ndi quartz, koma matenthedwe amatenthedwe ndi apamwamba kuwirikiza kakhumi kuposa a quartz.Pa kutentha kwambiri ali ndi lubricity wabwino, ndi wabwino kutentha olimba lubricant, ali amphamvu nyutroni mayamwidwe mphamvu, mankhwala bata, pafupifupi zitsulo zonse sungunuka ndi inertness mankhwala.
Hexagonal boron nitride insoluble m'madzi ozizira, madzi otentha hydrolysis ndi wodekha kwambiri ndi kutulutsa pang'ono boric acid ndi ammonia, ndi asidi ofooka ndi amphamvu m'munsi pa firiji si zotakasika, pang'ono sungunuka mu otentha asidi, ndi wosungunuka sodium hydroxide, potaziyamu. chithandizo cha hydroxide chikhoza kuwonongeka.Ili ndi kukana kwa dzimbiri kwa mitundu yonse ya asidi, alkali, njira yamchere ndi zosungunulira organic.
1, boron nitride ndi yopanda poizoni, kukana kutentha kwambiri, kukana kwa dzimbiri, kutentha kwambiri.
2. Sikuti insulator yamagetsi yokha komanso woyendetsa matenthedwe, electrolysis yapadera ndi
3, itha kugwiritsidwa ntchito ngati semiconductor solid-phase doped material, anti-oxidation kapena mafuta osagwira madzi.
4. Mafuta otentha kwambiri ndi nkhungu yotulutsa nkhungu, ufa wa boron nitride ungagwiritsidwenso ntchito ngati
5. Zinthu zolimba kwambiri zokonzedwa ndi boron nitride zitha kupangidwa kukhala zida zodula kwambiri
6. Zipangizo zamakina a ma atomiki, ma nozzles a ndege ndi ma roketi, zida zonyamula
7, yopanda poizoni komanso yopanda vuto komanso mafuta, itha kugwiritsidwa ntchito ngati zodzikongoletsera.
8. Pogwiritsa ntchito chothandizira, imatha kusinthidwa kukhala kiyubiki ya boron nitride yolimba ngati diamondi.
9, chitani mitundu yosiyanasiyana ya ma capacitor aluminium plating, machubu a aluminiyamu plating, chiwonetsero cha aluminium,
10, transistor heat seal desiccant ndi pulasitiki utomoni ndi zina polima zina.
11, mitundu yonse ya laser anti-counterfeiting aluminiyamu plating, trademark bronzing zipangizo, mitundu yonse ya ndudu zolemba, malembo mowa, mabokosi kulongedza, ndudu kulongedza mabokosi aluminiyamu plating ndi zina zotero.

Kapena akhoza kusinthidwa malinga ndi zosowa za makasitomala
