Muaj Cov Hom Ntawm Cov Khoom Siv Boron Nitride Ceramic
Aug 10, 2023
Boron nitride ceramics hais txog cov khoom siv ceramic uas yog tsim los ntawm boron nitride, cov tshuaj lom neeg ua los ntawm boron thiab nitrogen atoms. Muaj ntau ntau hom boron nitride ceramics, txhua tus muaj nws tus kheej cov khoom thiab kev siv.
Ib hom boron nitride ceramic yog kub nias boron nitride, uas feem ntau yog siv rau hauv cov ntawv thov kub. Nws muaj peev xwm tiv taus qhov kub txog li 1900 degree thiab yog siv dav hauv kev lag luam aerospace rau kev tsim cov nozzles, pwm, thiab lwm yam khoom siv kub.
Lwm hom boron nitride ceramic yog hexagonal boron nitride, uas muaj thermal conductivity zoo heev thiab hluav taws xob rwb thaiv tsev. Nws feem ntau yog siv los ua cov khoom siv hluav taws xob hauv hluav taws xob thiab ua cov roj nplua nyeem hauv cov ntawv thov kub.
Boron nitride ceramics kuj muaj ntau qhov zoo dua li cov tsoos ceramics. Lawv muaj cov thermal thiab tshuaj lom neeg ruaj khov zoo, tiv taus hnav thiab tsim kua muag, thiab ua siab ntev rau qhov kub thiab txias. Lawv kuj tsis muaj tshuaj lom thiab biocompatible heev, ua rau lawv haum rau siv hauv kev kho mob.
Hauv cov ntsiab lus, boron nitride ceramics muaj ntau yam kev siv thiab muaj ntau yam zoo dua li cov tsoos ceramics. Lawv yog cov khoom tseem ceeb hauv kev lag luam xws li aerospace, electronics, thiab kev kho mob.
