Nqe lus piav qhia:
Cov qauv siv lead ua ntawm hexagonal boron nitride muaj cov txheej txheem txheej zoo ib yam li graphite, qhia xoob, lubricating, yooj yim nqus dej noo, lub teeb yuag thiab lwm yam khoom ntawm cov hmoov dawb, yog li nws tseem hu ua "dawb graphite".Qhov ceev theoretical yog 2.27g / cm³, qhov tshwj xeeb lub ntiajteb txawj nqus yog 2.43, thiab Mohs hardness yog 2.
Hexagonal boron nitride muaj qhov zoo ntawm cov khoom tsis zoo, lubricity zoo, hluav taws kub thiab kev ua haujlwm yooj yim ntawm cov khoom siv kho tshuab.
Hais txog cov yam ntxwv ntawm hluav taws xob, nws muaj qhov zoo ntawm lub zog dielectric zoo, tsis tshua muaj hluav taws xob tsis tu ncua, tsis tshua muaj hluav taws xob tsis zoo, kev nkag mus rau microwave, thiab hluav taws xob rwb thaiv tsev zoo.
Hexagonal boron nitride muaj qhov zoo ntawm cov cua kub conduction, siab kub muaj peev xwm, tsis tshua muaj thermal expansion, thermal shock resistance, kub lubrication thiab kub kev nyab xeeb nyob rau hauv cov nqe lus ntawm thermal yam ntxwv.
Raws li cov khoom siv tshuaj lom neeg, nws muaj qhov zoo ntawm cov tshuaj lom neeg ruaj khov, tiv thaiv corrosion, oxidation tsis kam, tsis ntub dej, thiab tsis nplaum.
Ultra-fine boron nitride hmoov tuaj yeem siv rau hauv cov txheej txheem.Boron nitride txheej yog inert inorganic high-temperature lubricating khoom.Nws tsis adhere los yog infiltrate cov hlau molten.Nws tuaj yeem tiv thaiv cov refractory uas yog nyob rau hauv kev sib cuag ncaj qha nrog molten aluminium, magnesium, zinc alloy thiab molten slag Cov khoom los yog cov khoom siv ntawm cov khoom siv ceramic zoo heev rau kev pab cuam lub neej ntawm cov tais diav.
Qhov zoo ntawm boron nitride siv hauv txheej:
Tsis muaj kuab paug rau ib puag ncig, tsis muaj kev puas tsuaj rau tib neeg lub cev.Tsis muaj tshuaj lom, tsis muaj ntxhiab tsw ntxhiab.Tsis muaj kev pheej hmoo ntawm combustion lossis tawg.
Ua haujlwm kub zoo, mus txog 400 ~ 1700 ℃.Anti-corrosion kev ua tau zoo thiab kev ua haujlwm ntev.Paub nws tus kheej kho ntawm chav tsev kub.Resistant rau kev laus thiab hluav taws xob.Zoo dej tsis kam, ntsev tsuag kuj, thiab organic hnyav kuj.
Lub txheej muaj lub zog sib txuas nrog lub substrate.Cov txheej muaj siab hardness, tsis kam rau kev sib txhuam thiab kev cuam tshuam.
