Koj Paub Ntau npaum li cas txog qhov Hardness ntawm Boron Nitride Ceramics
Dec 19, 2023
Koj paub ntau npaum li cas txog qhov hardness ntawm boron nitride ceramics? Boron nitride ceramics yog ib hom khoom siv tawv tawv heev uas tuaj yeem ua rau muaj kev kub ntxhov, hluav taws xob rwb thaiv tsev zoo heev, thiab qis thermal expansion coefficient. Cov yam ntxwv tshwj xeeb no ua rau lawv xav tau ntau yam kev siv, xws li kev tsim khoom lag luam mus rau aerospace thiab kev tiv thaiv.
Lub hardness ntawm boron nitride ceramics yog ntaus nqi rau lawv cov qauv siv lead ua, uas zoo ib yam li cov pob zeb diamond. Lawv yog tsim los ntawm covalently bonded tes hauj lwm ntawm boron thiab nitrogen atoms uas tsim muaj zog thiab nruj tetrahedral qauv. Cov qauv siv lead ua no, ua ke nrog lub siab melting point ntawm boron nitride ceramics, ua rau lawv tshwj xeeb nyuaj thiab tiv taus deformation.
Boron nitride ceramics yog siv nyob rau hauv ntau yam ntawm cov cuab yeej txiav, sib tsoo lub log, thiab abrasives vim lawv hnav tsis kam thiab toughness. Lawv kuj tau siv nyob rau hauv kev lag luam electronics raws li substrates rau high-power devices, qhov twg lawv zoo heev hluav taws xob rwb thaiv tsev zog ua kom ntseeg tau kev ua tau zoo nyob rau hauv tej yam kev mob.
Ntxiv rau lawv cov khoom zoo heev thiab cov khoom siv hluav taws xob, boron nitride ceramics kuj yog biocompatible thiab chemically inert, ua rau lawv zoo tagnrho cov ntaub ntawv rau kev kho mob cog thiab lwm yam kev siv nyob rau hauv biomedical engineering.
Zuag qhia tag nrho, lub hardness ntawm boron nitride ceramics yog ib qho zoo kawg li tus cwj pwm uas ua rau lawv muaj ntau yam thiab muaj txiaj ntsig cov ntaub ntawv hauv ntau qhov chaw. Raws li kev tshawb fawb txuas ntxiv, nws zoo li peb yuav pom ntau daim ntawv thov rau cov khoom siv zoo kawg no, txuas ntxiv nthuav nws cov txiaj ntsig thiab cuam tshuam rau tib neeg.
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.
