Beryllium (Be) yog lub teeb hlau (txawm hais tias nws qhov ceev yog 3.5 npaug ntawm lithium, nws tseem sib zog dua li txhuas, nrog tib lub ntim ntawm beryllium thiab txhuas, qhov loj ntawm beryllium tsuas yog 2/3 ntawm txhuas). .Nyob rau tib lub sijhawm, lub melting point ntawm beryllium yog siab heev, siab li 1278 ℃.Beryllium muaj kev tiv thaiv corrosion zoo heev thiab lub zog siab.Lub caij nplooj ntoos hlav ua los ntawm beryllium tuaj yeem tiv taus ntau dua 20 billion qhov cuam tshuam.Nyob rau tib lub sijhawm, nws kuj tiv thaiv cov hlau nplaum, thiab tseem muaj cov yam ntxwv ntawm kev tsis tsim cov nplaim taws thaum ua haujlwm.Raws li cov hlau, nws cov khoom zoo heev, tab sis vim li cas beryllium tsis tshua pom hauv lub neej?

Nws muab tawm tias txawm hais tias beryllium nws tus kheej muaj cov khoom zoo tshaj plaws, nws daim ntawv hmoov muaj qhov muaj zog ua rau muaj kev phom sij.Txawm tias cov neeg ua haujlwm tsim khoom yuav tsum hnav cov kev tiv thaiv xws li khaub ncaws tiv thaiv kom tau cov hmoov beryllium uas tuaj yeem siv rau kev ua haujlwm.Ua ke nrog nws tus nqi kim, muaj ob peb lub sijhawm rau nws tshwm sim hauv khw.Txawm li cas los xij, muaj qee qhov chaw uas nws tsis yog nyiaj phem yuav pom nws muaj.Piv txwv li, cov hauv qab no yuav qhia:

Vim tias beryllium (Be) yog lub teeb thiab muaj zog, nws feem ntau siv rau hauv kev tiv thaiv daim ntawv thov, xws li ib feem ntawm missiles, rockets, thiab satellites (feem ntau siv los ua gyroscopes).Ntawm no, nyiaj tsis muaj teeb meem ntxiv lawm, thiab lub teeb thiab lub zog siab tau dhau los ua nws daim npav trump hauv daim teb no.Ntawm no, ib yam nkaus, tuav cov khoom siv tshuaj lom los ua qhov kawg uas yuav tsum txhawj txog.

Lwm cov cuab yeej ntawm beryllium ua rau nws yog ib qho cuab yeej tseem ceeb hauv kev lag luam niaj hnub no.Beryllium tsis tsim sparks thaum kev sib txhuam thiab kev sib tsoo.Ib feem pua ​​​​ntawm beryllium thiab tooj liab yog tsim rau hauv high-strength, non-sparking alloys.Xws li cov alloys ua lub luag haujlwm tseem ceeb hauv cov roj qhov dej thiab cov chaw ua haujlwm roj hluav taws xob.Nyob rau hauv cov chaw zoo li no, sparks los ntawm cov cuab yeej hlau tuaj yeem ua rau muaj kev puas tsuaj loj, uas yog cov foob pob hluav taws loj.Thiab beryllium tsuas yog txwv tsis pub nws tshwm sim.

Beryllium muaj lwm yam kab txawv siv: Nws yog pob tshab rau X-rays, yog li nws tuaj yeem siv los ua lub qhov rais hauv X-ray raj.X-ray raj yuav tsum muaj zog txaus kom muaj lub tshuab nqus tsev zoo, tab sis nyias txaus kom tso cai rau X-rays dhau mus.

Beryllium yog qhov tshwj xeeb heev uas nws ua rau tib neeg nyob deb thiab tib lub sijhawm tawm lwm cov hlau tawm mus.
