Boron carbide ceramic Cheebtsam thiab ceramic phaj yog super-nyuaj cov ntaub ntawv nrog tsawg ntom, siab hardness, siab modulus, siab thermal conductivity, siab melting point thiab zoo heev hnav tsis kam. Lawv tuaj yeem siv rau hauv cov khoom siv hauv tshuaj, tshuaj, zaub mov thiab lwm yam lag luam. Neutron shielding cov ntaub ntawv yog siv rau hauv kev siv hluav taws xob nuclear, kev tiv thaiv hluav taws xob, tshuaj nuclear thiab lwm yam haujlwm. Lawv kuj tuaj yeem siv los ua cov mos txwv tsis muaj phom, lub tsho tiv thaiv tank, thiab cov tsho tiv thaiv mos txwv.
Boron carbide ceramic sealing rings yog dav siv nyob rau hauv ntau lub sijhawm uas yuav tsum tau muaj kev sib khi zoo, xws li cov khoom siv hauv tshuaj, tshuaj, zaub mov thiab lwm yam lag luam. Nws tuaj yeem zam cov xov xwm tawm thiab ua kom lub cev ua haujlwm ntawm cov khoom siv. Muaj peev xwm ua tiav rau hauv cov duab thiab qhov ntau thiab tsawg raws li xav tau.
Raws li ib qho tseem ceeb neutron shielding khoom, boron carbide yog dav siv nyob rau hauv nuclear zog daim ntaub ntawv, hluav taws xob tiv thaiv thiab nuclear tshuaj. Muaj peev xwm ua tiav rau hauv cov duab thiab qhov ntau thiab tsawg raws li xav tau.
Boron carbide mos txwv daim hlau yog dav siv nyob rau hauv ib tug neeg tiv thaiv, ntau yam low-altitude aircraft thiab ib co armored tsheb. Lawv kuj tau siv los ua cov khoom ntawm ballistic vests, xws li cov mos mos ballistic linings thiab me me arms tiv thaiv inserts (SAPI).
