SUOYI Boron Nitride Ifu BN itandatu ya boron nitride HBN CBN RBN WBN

Nitride ya Boron ni kristu igizwe na atome ya azote na atome ya boron. Imiterere ya kristu igabanyijemo nitride ya boron ya hexagonal (HBN), nitride ya boron itandatu yuzuye (WBN) na nitride cubic boron. Imiterere ya kristu ya nitride ya hexagonal ifite imiterere isa na grafite, yerekana imyanda irekuye, isize amavuta, kwinjiza neza byoroshye, uburemere bworoshye nibindi biranga ifu yera, bityo nanone yitwa "grafite yera".

Ubucucike bwa Theoretical 2.27g / cm3, uburemere bwihariye: 2.43, Mo gukomera ni 2.

Nitriding ya hexagonal ifite amashanyarazi meza, itwara ubushyuhe bwumuriro, ituze ryimiti, ntahantu hagaragara gushonga, kurwanya ubushyuhe muri azote 0.1MPA kugeza 3000ºC, mukutabogama kwikirere, kurwanya ubushyuhe kuri 2000ºC, azote na argon mugukoresha ubushyuhe birashobora kugera kuri 2800ºC, mu kirere cya ogisijeni ihagaze nabi, ikoreshwa ry'ubushyuhe buri munsi ya 1000ºC.

Hexagonal boron nitride ifite coefficente yo kwaguka nka quartz, ariko ubushyuhe bwayo bwumuriro bwikubye inshuro icumi za quartz. Ifite kandi amavuta meza ku bushyuhe bwo hejuru, ni amavuta meza yo mu rwego rwo hejuru cyane, afite imbaraga zo kwinjiza neutron, imbaraga za chimique, kandi yinjizwamo imiti hafi ya byose byashongeshejwe.

Hexagonal boron nitriding idashobora gukama amazi akonje, amazi atetse hydrolysis aratinda cyane kandi akabyara aside irike ya boric na ammonia, hamwe na aside idakomeye hamwe nishingiro rikomeye mubushyuhe bwicyumba ntibitwara, bigashonga gato muri acide ishyushye, hamwe na hydroxide ya sodium ya sodium, potasiyumu hydroxide kwivuza kubora. Ifite ruswa irwanya aside aside itandukanye, ibishingwe, ibisubizo byumunyu hamwe nudukoko twangiza.

Kurwanya ubushyuhe

Str Ubushyuhe butajegajega (kugeza 1000˚C mu kirere, 1400˚ mu cyuho, na 2800˚ C mu kirere kitagira ingano)

Hexagonal boron nitride ni ubwoko bwibikoresho byateye imbere. Microstructure yayo iranyeganyega kandi imiterere ya molekuline ni kristu ya mpandeshatu. Hexagonal boron nitride ifite umwihariko kandi mwiza wumubiri nubumara. Ifite ubushyuhe bwiza cyane, kubika amashanyarazi, kurwanya ruswa no kurwanya okiside. Irashobora kwihanganira gushika 1000OC mu kirere, hamwe na 2000OC muri gaze ya inert na vacuum. Nitride ya kirisiti ya kirisiti yacumishijwe ku bushyuhe bwo hejuru bwa 2000OC, hamwe n’imiti ihamye y’imiti n’umubiri hamwe n’ubushuhe buhebuje bw’ubushyuhe (ubushyuhe bw’umuriro wa kirisiti imwe ni 250-300W / mk). Kugeza ubu, uruganda rukora ifu ya flake kristalline ifite ubunini bumwe bwa kirisiti ingana na micrometero 500 nanometero 20 na nanoscale spherical boron nitride.

Hexagonal boron nitride itoneshwa ninganda za elegitoronike kubera imiterere idasanzwe yubushyuhe bwo hejuru bwumuriro nubushakashatsi bwamashanyarazi. Abakora ibikoresho bya elegitoroniki yo mu gihugu no mu mahanga bakoze ubushakashatsi bunini bwo gukoresha amashanyarazi muri plastiki y’amashanyarazi, gupakira semiconductor no kuzuza, gupakira ubushyuhe bwa LED, n'ibindi. inganda za nitride.

Inganda zimwe zisanzwe zungukirwa na boron nitride ceramics zirimo:

Ikirere

● Guhindura ibyuma

Ibyuma bya elegitoroniki

Gushyushya no gukonja

Gukora ibirahuri

● Igisirikare n’ingabo
