Qhov sib txawv ntawm Granular Boron Nitride Thiab Spherical Boron Nitride

Hexagonal Boron Nitride (hBN) thiab Cubic Boron Nitride (cBN) yog ob hom sib txawv ntawm boron nitride tebchaw uas muaj cov khoom sib txawv thiab cov yam ntxwv.

hBN, tseem hu ua dawb graphene, muaj txheej txheej hexagonal zoo ib yam li graphite. Nws yog ib qho zoo heev hluav taws xob insulator, muaj thermal conductivity, thiab resistant rau tshuaj thiab corrosion. Vim nws cov qauv anisotropic, hBN muaj qhov siab nruj ntawm ib qho kev taw qhia thiab tuaj yeem siv los ua tus muab tub lim los txhim kho lub zog thiab tawv ntawm cov khoom sib xyaw.

Ntawm qhov tod tes, cBN muaj cov qauv siv lead ua zoo ib yam li pob zeb diamond thiab yog ib qho ntawm cov ntaub ntawv nyuaj tshaj plaws rau txiv neej. Nws yog ib qho zoo heev abrasion-resistant thiab muaj zoo thermal stability, ua rau nws haum rau high-temperature daim ntaub ntawv. cBN yog dav siv los ua cov khoom siv txiav, tshwj xeeb tshaj yog nyob rau hauv machining ntawm cov ntaub ntawv nyuaj thiab abrasive.

Nyob rau hauv cov nqe lus ntawm morphology, hBN feem ntau yog tsim raws li platelets los yog flakes, thaum cBN yog synthesized nyob rau hauv ib tug spherical los yog cubic duab. Cov duab kheej kheej ntawm cBN muab thaj chaw ntau dua, ua kom yooj yim rau kev tawg thiab sib xyaw nrog lwm cov ntaub ntawv.

Txawm hais tias lawv qhov sib txawv, ob qho tib si hBN thiab cBN muaj cov khoom tshwj xeeb thiab muaj txiaj ntsig uas ua rau lawv muaj txiaj ntsig hauv ntau yam kev siv, suav nrog cov khoom siv hluav taws xob, cov khoom sib xyaw, thiab cov cuab yeej txiav.

Shengyang New Material Co., Ltd. tau cog lus rau kev tsim cov boron nitride thiab boron nitride ua cov khoom, thiab tuaj yeem kho ntau yam boron nitride insulating ceramic qhov chaw raws li cov neeg siv khoom xav tau. Tiv tauj peb yog tias tsim nyog.
