Khoom Piav Qhia

Boron nitride yog ua los ntawm nitrogen thiab boron atoms hauv cov siv lead ua, cov qauv siv lead ua tuaj yeem muab faib ua:

hexagonal boron nitride (HBN), cov kab ntawm ntom ntom ntawm hexagonal boron nitride thiab cubic boron nitride, cov siv lead ua

tus qauv ntawm hexagonal boron nitride muaj cov qauv zoo sib xws graphite txheej, xoob, lubrication, yooj yim nqus

ntawm kev ya raws, lub teeb thiab lwm cov cwj pwm ntawm cov hmoov dawb dawb, hais dua yog li "graphite dawb. Kev ntsuas lub zog: 2.27g / cm3,

lub ntiajteb txawj nqus tshwj xeeb: 2.43, mossberg hardness: 2. Hexagonal boron nitride muaj hluav taws xob zoo hluav taws xob,

thermal conductivity, tshuaj lom neeg ruaj khov, tsis muaj cuab kav pom kev ua kom sov, kub tiv taus txog 3000 ℃ hauv 0.1 MPA nitrogen,

nyob rau hauv qhov nruab nrab txo cov huab cua, cov cua sov tiv txog 2000 ℃, cov pa nitrogen thiab argon siv rau qhov kub thiab txias

tuaj yeem ncav cuag 2800 ℃, kev ruaj khov tsis zoo hauv cov pa oxygen, qhov kub qis dua 1000 ℃. Kev nthuav dav coefficient ntawm

boron nitride yog sib npaug ntawm quartz, tab sis cov thermal conductivity yog kaum zaus dua li ntawm quof quartz.

Nyob rau hauv high school kub kuj muaj zoo lubricity, yog zoo zoo kub roj nplua nyeem, muaj ib qho muaj zog neutron

lub peev xwm nqus tau, tshuaj kom ruaj khov, yuav luag txhua cov hlau molten muaj tshuaj lom neeg.

Hexagonal boron nitride insoluble hauv dej txias, dej rhaub hydrolysis qeeb heev thiab tsim cov khoom me me

ntawm boric acid thiab ammonia, thiab cov kua qaub uas tsis muaj zog thiab lub hauv paus muaj zog ntawm chav tsev kub tsis muaj kev hloov pauv, soluble me ntsis

nyob rau hauv cov kua qaub kub, nrog molten sodium hydroxide, kev kho potassium hydroxide tuaj yeem decomposed. Nws muaj qhov zoo

kev txhim kho corrosion rau txhua yam ntawm inorganic acid, alkali, kua ntsev thiab cov kuab tshuaj organic.

Thov

1, boron nitride yog non-toxic, siab kub ua hauj, kev tiv thaiv corrosion, siab thermal

conductivity, rwb thaiv tsev siab, zoo heev kev ua tau zoo ntawm cov khoom siv.

2. Nws tsis yog tsuas yog hluav taws xob thaiv hluav taws xob tab sis kuj muaj cov kab hluav taws xob thermal, lub ntsuas hluav taws xob tshwj xeeb thiab
tsis kam cov khoom ntawm qhov kub thiab txias, qhov ntsuas hluav taws xob ntawm qhov ntsuas hluav taws xob siab thiab cov hluav taws xob ntau
thiab ntshav arc.

3, tuaj yeem siv ua semiconductor khoom-theem doped khoom, tiv thaiv oxidation lossis kua roj-resistant.

4. Cov tshuab ua kom sov siab thiab pwm tso tus neeg saib xyuas, boron nitride hmoov kuj tseem siv tau
tus neeg sawv cev tiv thaiv kev ywj pheej rau iav hlaws dai, pwm tso tus neeg sawv cev rau iav thiab hlau ua.

5. Cov khoom siv ua tawv tawv ua tiav los ntawm boron nitride tuaj yeem ua rau hauv cov cuab yeej txiav siab kub
thiab cov khoom rau qhov khawb rau kev tshawb kawm geological thiab roj twj.

6. Cov cuab yeej khoom tsim ntawm atomic reactors, nozzles ntawm cov dav hlau thiab cov tshuab foob pob zeb, cov khoom ntim khoom
txhawm rau tiv thaiv cov hluav taws xob neutron, thiab cov ntaub thaiv npog thermal hauv aerospace.

7, non-toxic thiab harmless thiab lubricity, tuaj yeem siv los ua cov tshuaj pleev kom pleev zoo nkauj.

8. Nrog rau kev koom tes ntawm catalyst, nws tuaj yeem hloov mus rau hauv cubic boron nitride nyuaj li pob zeb diamond
tom qab kub thiab siab kho kho.

9, ua ntau yam ntawm capacitor zaj duab xis aluminium plating, duab raj txhuas plating, txhuas zaub,
xws li lub nkoj evaporation.

10, transistor tshav kub foob desiccant thiab yas yas thiab lwm yam polymer ntxiv.

11, txhua hom laser los tiv thaiv kev lag luam aluminium plating, cov cim ua cim rau cov khoom siv tooj daj, txhua hom ntawv luam yeeb, daim ntawv lo npias, ntim thawv, ntawv ntim hauv cov ntawv luam yeeb aluminium plating thiab lwm yam.
