Kev piav qhia Ntawm Cov Khoom Thiab Kev Siv Ntawm Hexagonal Boron Nitride Powder

Hexagonal boron nitride hmoov, tseem hu ua h-BN, yog cov khoom siv ceramic uas nthuav tawm ntau yam khoom tshwj xeeb. Nws yog cov khoom siv hluavtaws uas yog tsim los ntawm boron thiab nitrogen atoms hauv hexagonal lattice.

Ib qho ntawm cov khoom tseem ceeb tshaj plaws ntawm h-BN hmoov yog nws qhov tshwj xeeb thermal stability. Nws muaj qhov melting point ntau dua 3,{2}} degree, ua rau nws yog ib qho khoom siv zoo tshaj plaws rau kev siv kub. Nws kuj tiv taus oxidation thiab yog ib qho zoo heev insulator, ua rau nws zoo tagnrho rau siv nyob rau hauv hluav taws xob Cheebtsam.

h-BN hmoov kuj tseem muaj roj nplua nyeem thiab muaj cov coefficient ntawm kev sib txhuam, ua rau nws yog ib qho khoom siv zoo tshaj plaws rau kev siv roj nplua nyeem thiab txheej txheej. Nws kuj tseem muaj zog mechanically thiab muaj kev hnav zoo, ua rau nws muaj txiaj ntsig zoo rau ntau yam kev siv hauv kev lag luam.

Lwm cov cuab yeej tshwj xeeb ntawm h-BN hmoov yog nws qhov pom kev pom tseeb hauv thaj chaw pom thiab ze-infrared. Qhov no ua rau nws yog ib qho khoom siv zoo heev rau siv hauv cov khoom siv kho qhov muag thiab hluav taws xob xws li LEDs thiab hnub ci hlwb.

Zuag qhia tag nrho, h-BN hmoov muaj ntau yam kev siv hauv kev lag luam xws li aerospace, electronics, zog, thiab lubricants. Nws cov khoom tshwj xeeb ua rau nws yog ib qho khoom siv txaus nyiam siv rau ntau yam kev ua haujlwm siab.

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.
