Kev piav qhia ntawm Beryllium Long Products
Beryllium (Be) yog nkig, steel-grey alkaline ntiaj teb hlau. Nws muaj zog, hnav, thiab muaj cov qauv ntawm elasticity 50 feem pua siab dua cov hlau. Nws tsis yog hlau nplaum thiab muaj cua sov tshwj xeeb tshaj li cov hlau. Beryllium khaws cov khoom zoo heev ntawm qhov kub thiab txias, ua rau cov hlau zoo nkauj no yog qhov zoo tshaj plaws thermal conductor.
Txawm tias nws toxicity, lub caij yog heev pab tau vim hais tias ntawm nws cov cim zoo. Nws yog alloyed nrog tooj liab los yog npib tsib xee los ua cov springs, gyroscopes, hluav taws xob tiv tauj, qhov chaw vuam electrodes thiab cov cuab yeej tsis muaj teeb meem. Lwm cov beryllium alloys yog siv nyob rau hauv high-speed aircrafts thiab missiles, nrog rau cov dav hlau thiab kev sib txuas lus satellites. Beryllium tooj liab kuj tseem siv tau rau hauv lub tshuab cua, nres discs, txhawb nqa kab, thiab lwm yam khoom siv ntawm qhov chaw shuttle. Ua tsaug rau nws qhov tsawg thermal neutron absorption cross-section, beryllium yog siv nyob rau hauv nuclear reactors raws li ib tug reflector los yog moderator. Ntxiv mus, lub siab melting point ntawm beryllium oxide ua rau nws yog ib qho tseem ceeb cov ntaub ntawv rau nuclear ua hauj lwm thiab ceramic daim ntaub ntawv.
