Yog vim li cas rau qhov txawv ntawm Porous Boron Nitride Thiab Cubic Boron Nitride
Oct 16, 2023
Porous boron nitride (pBN) thiab cubic boron nitride (cBN) yog ob hom sib txawv ntawm boron nitride nrog cov qauv sib txawv thiab cov khoom. Qhov sib txawv tseem ceeb ntawm lawv yog lawv cov qauv siv lead ua. pBN muaj cov txheej txheem txheej zoo ib yam li graphite, thaum cBN muaj cov qauv zoo li pob zeb diamond.
Cov khoom tshwj xeeb ntawm pBN ua rau nws yog ib qho khoom siv zoo nkauj rau ntau yam kev siv. Nws cov qauv ntxeem tau ua rau nws zoo heev insulator thiab thermal conductor, ua rau nws haum rau siv nyob rau hauv high-temperature ib puag ncig xws li aerospace thiab electronics. Nws thaj chaw loj thiab qhov porosity kuj ua rau nws muaj txiaj ntsig zoo rau catalysis thiab ua ib qho roj cia nruab nrab.
Ntawm qhov tod tes, cBN muaj qhov tshwj xeeb hardness thiab thermal stability, ua rau nws zoo tagnrho rau siv los ua cov khoom siv hauv kev txiav thiab sib tsoo. Nws kuj tseem siv rau hauv kev sim siab siab thiab ua lub dab dej kub hauv cov khoom siv hluav taws xob.
Hauv cov ntsiab lus, pBN thiab cBN muaj cov qauv siv lead ua sib txawv uas muab lawv cov khoom tshwj xeeb haum rau ntau yam kev siv. Ob qho khoom siv muaj peev xwm loj heev hauv ntau qhov chaw xws li aerospace, electronics, thiab kev lag luam. Yog li ntawd, kev tshawb fawb ntxiv thiab kev txhim kho ntawm cov ntaub ntawv no tuaj yeem ua rau muaj kev vam meej hauv kev siv tshuab thiab kev tshawb fawb.
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.
