Boron carbide (B4C) hu ua pob zeb diamond dub, feem ntau yog grey-dub micro-hmoov. Nws yog ib qho ntawm peb cov ntaub ntawv nyuaj tshaj plaws paub (lwm ob yog pob zeb diamond thiab cubic boron nitride), nrog rau Mohs hardness ntawm 9.3. Nws yog siv nyob rau hauv lub tank armor, mos mos vests, thiab ntau yam kev siv.
Main Khoom
Superhardness: Boron carbide yog cov khoom siv superhard nrog hardness ze rau pob zeb diamond. Yog li ntawd, nws yog feem ntau siv los ua abrasive thiab txiav cov cuab yeej hauv kev lag luam, xws li kev sib tsoo lub log thiab cov hniav.
Cov ntsiab lus melting siab: Boron carbide muaj qhov siab melting point, kwv yees li 2350 degree. Qhov no ua rau nws muaj kev ua tau zoo nyob rau hauv qhov kub thiab txias ib puag ncig thiab yog siv rau hauv cov ntaub ntawv refractory, high-temperature ceramics, thiab nuclear engineering.
Cov khoom siv hluav taws xob zoo heev:: Boron carbide muaj cov thermal conductivity zoo, ua rau nws siv dav hauv cov dab dej kub, cov ntsuas kub siab, thiab kev lag luam semiconductor.
Corrosion tsis kam: Boron carbide pom zoo corrosion kuj rau ntau cov tshuaj, tso cai rau nws siv nyob rau hauv kev lag luam kev siv nyob rau hauv corrosive ib puag ncig.
Cov ntawv thov tseem ceeb
Cov khoom siv armor
Vim nws superhardness thiab siab hardness, boron carbide yog siv los ua armor khoom rau kev tsim cov mos txwv vests, mos txwv tsheb, armor phaj, thiab lwm yam.
01
Cov cuab yeej txiav thiab abrasives
Lub hardness ntawm boron carbide ua rau nws yog ib qho khoom siv zoo heev rau kev txiav cov cuab yeej thiab cov abrasives, siv hauv kev ua hlau thiab lwm yam ntaub ntawv nyuaj.
02
Nuclear engineering
Vim nws qhov siab melting point thiab tsawg neutron absorption cross-section, boron carbide yog siv los ua flux thiab neutron absorber khoom hauv nuclear reactors.
03
Kev lag luam ceramic
Boron carbide tuaj yeem siv los tsim cov khoom kub kub, cov cuab yeej txiav ceramic, thiab cov ntaub ntawv refractory hauv kev lag luam steelmaking.
04
Kub dab dej
Boron carbide cov thermal conductivity zoo heev ua rau nws feem ntau siv los ua cov khoom siv rau cov khoom siv hluav taws xob ua haujlwm siab thiab cua sov dissipation nyob rau hauv high-temperature sensors.
Hauv cov ntsiab lus, boron carbide yog cov khoom siv ntau yam nrog kev siv dav hauv kev lag luam, khoom siv tiv thaiv, nuclear engineering, thiab lwm yam. Nws hardness, kub tsis kam, thiab corrosion kuj ua rau nws ua lub luag haujlwm tseem ceeb hauv cov xwm txheej tshwj xeeb.
