Qhov txawv thiab qhov zoo ntawm Boron Nitride Thiab Boron Carbide
Aug 23, 2023
Boron nitridethiab boron carbide yog ob yam khoom sib txawv uas muaj ntau yam tshwj xeeb thiab cov khoom. Thaum boron nitride yog tsim los ntawm nitrogen thiab boron atoms, boron carbide yog ib tug compound ntawm boron thiab carbon atoms. Ob qho khoom siv muaj ntau yam kev siv hauv kev lag luam sib txawv raws li lawv lub zog, thermal conductivity, thiab tshuaj lom neeg.
Boron nitride paub txog nws cov thermal conductivity, siab kub stability, thiab zoo heev dielectric zog. Nws yog siv dav hauv electronics, aerospace kev lag luam, thiab metallurgy. Boron nitride tiv taus oxidation thiab tsis tshua muaj thermal expansion, ua rau nws zoo tagnrho rau siv nyob rau hauv high-temperature ib puag ncig. Cov khoom siv no muaj kev siv hauv thermal tswj thiab cov dab dej kub, nrog rau kev tsim khoom semiconductors thiab optoelectronic li.
Boron carbide paub txog nws qhov tshwj xeeb hardness, abrasion tsis kam, thiab tshuaj stability. Nws yog siv feem ntau los ua cov khoom siv abrasive hauv kev lag luam xws li cov cuab yeej txiav, txheej, thiab daim ntaub ntawv hnav-resistant. Boron carbide kuj tseem siv rau hauv kev tsim khoom ntawm lub cev armor vim nws lub siab tawv thiab muaj peev xwm nqus tau qhov cuam tshuam. Cov khoom siv no yog ib tus neeg sib tw zoo tshaj plaws rau kev tsim cov khoom hnyav thiab cov cuab yeej siv ruaj khov rau kev ua tub rog thiab tub ceev xwm lub hom phiaj.
Zuag qhia tag nrho, ob qho tib si boron nitride thiab boron carbide yog cov khoom tshwj xeeb nrog cov yam ntxwv tshwj xeeb uas ua rau lawv zoo tagnrho hauv kev lag luam sib txawv. Lawv ob leeg muaj lub zog siab, thermal stability, thiab tiv thaiv corrosion, ua rau lawv muaj txiaj ntsig zoo hauv qhov chaw huab cua. Lawv kuj muaj kev ruaj ntseg zoo heev thiab hluav taws xob conductivity, ua rau lawv zoo tagnrho rau siv hauv electronics thiab optoelectronics. Kev nkag siab txog cov khoom ntawm ob cov ntaub ntawv no yog qhov tseem ceeb rau kev tsim cov thev naus laus zis tshiab thiab kev siv, thaum kawg ua rau kev nce qib hauv ntau yam.
