Boron Nitride Yabitswe BN Yabambwe
Amabwiriza y'ibicuruzwa
Boron Nitride, izwi kandi ku izina rya BN, Hexagonal Boron Nitride (H-BN), hamwe na Boron Nitride ikanda cyane, ni ceramic nziza cyane yo kwisiga ishobora kwihanganira ubushyuhe bwinshi kandi ikagumana ubushobozi bwayo bwo gusiga ahantu habi cyane.AEM ya Boron Nitride ibamba ikozwe muri boron nitride ishyushye.Hexagonal Boron Nitride (H-BN) yitwara kimwe na grafite mu buryo bwa tekinike ariko itanga amashanyarazi meza cyane.
Ibyingenzi
Nitride ya Boron ifite amashanyarazi meza, ubushyuhe bwumuriro, imiti ihamye, kandi ntahantu ho gushonga.Ubushuhe ntarengwa bwo gukoresha muri azote 0.1MPA burashobora gushika kuri 3000 ° C, mukirere kigabanya kutagira aho kibogamiye, kirashobora kwihanganira ubushuhe gushika kuri 2000 ° C, kandi ubushyuhe bwo gukoresha muri azote na argon burashobora gushika kuri 2800 ° C, kandi umutekano muke wa ogisijeni ni bikennye, kandi gukoresha ubushyuhe buri munsi ya 1000 ° C.Kwiyongera kwingingo ya nitride ya borone ya hexagonal ihwanye na quartz, ariko ubushyuhe bwumuriro bwikubye inshuro icumi ubwiza bwa quartz.
Byongeye kandi, nitride ya boron ya hexagonal ntishobora gushonga mumazi akonje, kandi iyo amazi atetse, hydrolysis iratinda cyane kandi itanga aside nkeya ya boric na ammonia.Ntabwo ikora hamwe na acide idakomeye hamwe nubushuhe bukomeye mubushyuhe bwicyumba, gushonga gake muri acide ishyushye, kandi igomba kuvurwa na hydroxide ya sodium yashongeshejwe hamwe na hydroxide ya potasiyumu kugirango ibore.

Gusaba ibicuruzwa
Nitride ya Boron ni ubwoko bwubushyuhe bwo hejuru, kurwanya ruswa, ubukana bwumuriro mwinshi, kubika cyane hamwe no gusiga amavuta meza yibikoresho, uko ibintu bimeze ubu kugirango byoroshe inzira, kugabanya ibiciro byumusaruro, kuzamura ubuzima bwa serivisi yibigize nubu bigikora cyane icyerekezo cyubushakashatsi bwibikoresho nkibi.
. gushonga ibyuma byuka.
.
. ibice byo gukwirakwiza ubushyuhe, hamwe no gukoresha inshuro nyinshi ibikoresho by'itanura ry'amashanyarazi.
