Boron nitride amapangidwa ndi nayitrogeni ndi ma atomu a boron mu kristalo, mawonekedwe a kristalo amatha kugawidwa mu:

hexagonal boron nitride (HBN), mizere yolimba ya hexagonal boron nitride ndi cubic boron nitride, kristalo

kapangidwe ka hexagonal boron nitride ali ofanana graphite wosanjikiza dongosolo, lotayirira, kondomu, mayamwidwe osavuta

chinyezi, kuwala ndi zina za ufa woyera, tibwerezanso kotero "graphite yoyera. Kachulukidwe ka chiphunzitso: 2.27g / cm3,

mphamvu yokoka: 2.43, kuuma kwa mossberg: 2. Hexagonal boron nitride is has good magetsi insulation,

matenthedwe otentha, kusasunthika kwa mankhwala, palibe malo osungunuka owonekera, otentha mpaka 3000 ℃ mu 0.1 MPA nayitrogeni,

mumalo ochepetsa ndale, osagwira kutentha mpaka 2000 ℃, nayitrogeni ndi argon imagwiritsidwa ntchito kutentha

Ikhoza kufika 2800 ℃, kukhazikika kochepa mumlengalenga, kutentha pansi pa 1000 ℃. Kukula koyefishienti kwa

boron nitride ndi wofanana ndi quartz, koma matenthedwe otentha ndiokwera kakhumi kuposa a quartz.

Kutentha kwambiri kumakhalanso ndi mafuta abwino, ndimatenthedwe otentha kwambiri, amakhala ndi neutron wamphamvu

mayamwidwe, kukhazikika kwamankhwala, pafupifupi zitsulo zonse zosungunuka zimakhala ndi kusakhazikika kwamankhwala.

Hexagonal boron nitride osasungunuka m'madzi ozizira, madzi otentha a hydrolysis amachedwa kwambiri ndipo amatulutsa pang'ono

ya boric acid ndi ammonia, ndi asidi wofowoka komanso wolimba kutentha sizitentheka, sungunuka pang'ono

mu asidi wotentha, wokhala ndi sodium hydroxide wosungunuka, mankhwala a potaziyamu hydroxide amatha kuwola. Ili ndi zabwino

dzimbiri kukana kwa mitundu yonse ya zochita kupanga asidi, soda, mchere njira ndi zosungunulira organic.

Kugwiritsa ntchito

1, boron nitride ndi yopanda poizoni, kutentha kwambiri, kukana kutu, kutentha kwambiri

madutsidwe, kutchinjiriza kwakukulu, magwiridwe antchito abwino kwambiri.

2. Sikuti imangokhala yotetezera magetsi komanso yotenthetsera mafuta, yamagetsi yamagetsi yapadera komanso
kukana zinthu pa kutentha kwambiri, ndi insulator wa voteji mkulu ndi mkulu pafupipafupi magetsi
ndi arc plasma.

3, itha kugwiritsidwa ntchito ngati semiconductor yolimba-gawo doped zakuthupi, anti-makutidwe ndi okosijeni kapena mafuta osagwira madzi.

4. Mafuta otentha otsekemera komanso otulutsa nkhungu, boron nitride ufa amathanso kugwiritsidwa ntchito ngati
anti-adhesion wothandizila mikanda yamagalasi, wothandizila kutulutsa nkhungu wamagalasi ndi chitsulo.

5. Zinthu zolimba kwambiri zomwe zimakonzedwa ndi boron nitride zimatha kupangidwa kukhala zida zothamanga kwambiri
ndi kuboola tinthu tating'onoting'ono tofufuza za geological ndikuboola mafuta.

6. Zida zomangamanga zamagetsi a atomiki, ma nozzles a injini za ndege ndi rocket, zopangira ma CD
kupewa ma radiation a neutron, ndi zotetezera zotenthetsera mumlengalenga.

7, yopanda poizoni komanso yopanda vuto lililonse komanso yamafuta, itha kugwiritsidwa ntchito ngati zodzikongoletsera.

8. Pogwiritsa ntchito chothandizira, imatha kusandulika kukhala cubic boron nitride yolimba ngati diamondi
pambuyo kutentha ndi kuthamanga chithandizo.

9, chitani mitundu ingapo yama capacitor opanga ma aluminiyamu, chithunzi cha chubu cha aluminiyamu, chiwonetsero cha aluminium,
monga bwato lamadzi.

10, transistor kutentha chisindikizo desiccant ndi pulasitiki utomoni ndi zina zowonjezera polima.

11, mitundu yonse yama laser anti-counterfeiting aluminiyamu, zotengera zopangira chizindikiro, mitundu yonse ya ndudu, zolemba za mowa, mabokosi opakira, mabokosi osungira ndudu zotayidwa ndi zina zambiri.
