Beryllium yog cov khoom tsim tawm.Beryllium yog ib yam khoom tseem ceeb thiab muaj txiaj ntsig hauv atomic zog, foob pob ua ntxaij, missiles, aviation, aerospace thiab metallurgical industries.Nws tuaj yeem pom tias beryllium muaj ntau yam kev siv hauv kev lag luam.
Ntawm tag nrho cov hlau, beryllium muaj lub peev xwm tshaj plaws los xa cov duab X-rays thiab paub tias yog iav hlau, yog li beryllium yog ib qho khoom siv tsis tuaj yeem ua rau lub qhov rais me me hauv X-ray raj.
Beryllium yog cov khoom muaj nqis ntawm kev lag luam atomic zog.Hauv atomic reactors, beryllium tuaj yeem muab cov neutron qhov chaw rau ntau lub plhaub neutron (ua tau ntau pua txhiab tus neutrons ib ob);Nyob rau hauv tas li ntawd, nws muaj ib tug muaj zog deceleration nyhuv ntawm ceev neutrons, uas yuav ua rau fission tshua nws mus ntxiv mus, yog li ntawd beryllium yog qhov zoo tshaj plaws neutron moderator nyob rau hauv lub atomic reactor.Txhawm rau tiv thaiv cov neutrons los ntawm kev khiav tawm ntawm lub reactor thiab ua rau muaj kev nyab xeeb ntawm cov neeg ua haujlwm, yuav tsum muaj lub voj voog ntawm cov neutron reflectors nyob ib ncig ntawm lub reactor kom yuam cov neutrons uas sim khiav tawm ntawm lub reactor rov qab mus rau lub reactor.Nyob rau hauv txoj kev no, beryllium oxide tuaj yeem tsis tsuas yog cuam tshuam cov neutrons rov qab, tab sis kuj yog cov khoom siv zoo tshaj plaws rau cov neutron reflection txheej hauv lub reactor vim nws qhov siab melting point, tshwj xeeb tshaj yog nws cov kub tsis kam.
Beryllium kuj yog cov khoom siv dav hlau zoo.Nyob rau hauv cov khoom siv satellites, tag nrho qhov hnyav ntawm lub tsheb pib nce txog 500kg rau txhua kilogram ntawm satellite qhov hnyav.Yog li ntawd, cov khoom siv rau kev ua cov foob pob hluav taws thiab satellites xav tau lub teeb yuag thiab lub zog siab.Beryllium yog sib zog dua li feem ntau siv txhuas thiab titanium, thiab nws lub zog yog plaub npaug ntawm cov hlau.Tsis tas li ntawd, beryllium muaj peev xwm nqus tau cov cua sov thiab yog qhov ruaj khov.
Hauv kev lag luam metallurgical, ntsuab hlau uas muaj 1% mus rau 3.5% beryllium yog hu ua beryllium bronze, uas tsis tsuas yog muaj cov khoom zoo dua li cov hlau, tab sis kuj muaj kev tiv thaiv corrosion zoo thiab muaj peev xwm tswj tau hluav taws xob zoo.Yog li ntawd, bronze beryllium tuaj yeem siv los ua hairsprings hauv watches, high-speed bearings, submarine cables, thiab lwm yam.
Vim hais tias beryllium bronze uas muaj ib co nyiaj npib tsib xee tsis tsim sparks thaum nws raug ntaus, beryllium yuav siv tau los ua chisels, hammers, xyaum, thiab lwm yam rau roj av thiab tsuas industries, yog li tiv thaiv hluav taws thiab tawg xwm txheej.Tsis tas li ntawd, nickel-muaj beryllium bronze tuaj yeem siv los ua cov khoom siv hlau nplaum vim nws tsis nyiam los ntawm cov hlau nplaum.
