Cov txheej txheem ua haujlwm yas tsim cov khoom siv beryllium thiab beryllium alloys.
Kev tsim khoom ntawm beryllium hlau thiab beryllium-muaj alloys tau pib hauv xyoo 1920.
Thaum Ntiaj Teb Tsov Rog II, kev lag luam beryllium tau txais txiaj ntsig ntau
kev loj hlob.
Txij li thaum nruab nrab-1960s, beryllium tau siv nyob rau hauv kev lag luam aerospace, thiab kev tshawb fawb ntawm beryllium cov ntaub ntawv tau nyob rau hauv lub 40s.
Hauv xyoo 1990, nws tsuas yog daws qhov teeb meem ntawm cov txheej txheem casting thiab extrusion ntawm beryllium;Xyoo 1947, cov hmoov metallurgy tau tsim
Cov txheej txheem kub rau kev ua neej nyob;Nyob rau hauv thaum ntxov 70s, lub mechanism ntawm microalloying tau mastered, thiab kev cuam tshuam tau siv
Sib tsoo, electrorefining, kub isostatic nias thiab hmoov pretreatment txheej txheem, kom lub zog ntawm beryllium khoom
Cov khoom siv tshuaj muaj txiaj ntsig tau zoo dua qub (qhov elongation nce ntawm 1% mus rau 3 ~ 4%).
Txoj kev loj hlob ntawm cov ntaub ntawv beryllium nyob rau hauv Tuam Tshoj pib nyob rau hauv 1958, thiab nyob rau hauv 1970s, lub high-throughput xeem cov tshuaj tiv thaiv tau ntse tsim.
Beryllium Cheebtsam thiab ntau yam ntaub ntawv beryllium rau reactors.
Tam sim no, lub ntiaj teb feem ntau suav nrog Tebchaws Meskas, Russia, Kazakhstan, Tuam Tshoj, Brazil,
Argentina thiab ob peb lub teb chaws nyob rau hauv teb chaws Africa mine beryllium ore, tab sis cov txheej txheem los ntawm ore ua rau cov khoom beryllium
Kev tsim khoom tsuas yog hauv Asmeskas, Kazakhstan thiab Tuam Tshoj.
1) Lub hauv paus chiv keeb ntawm hlau beryllium Beryllium yog thawj zaug hu ua Glucinium, uas tuaj ntawm tim Nkij teb chaws
Lo lus glykys txhais tau tias qab zib, vim hais tias cov ntsev ntawm beryllium muaj qab zib.
Txij li cov ntsev ntawm yttrium kuj muaj qab zib, Wheeler hu ua Beryllium tom qab.
Nws yog muab los ntawm lus Askiv lub npe ntawm beryl, lub ntsiab ore ntawm beryllium.
Lub cim cim yog Be, thiab Suav lub npe yog beryllium.
Beryllium, atomic tooj 4, atomic hnyav 9.012182, yog lub lightest alkaline ntiaj teb hlau ntsiab.
Thaum cov tshuaj ntsuam xyuas ntawm beryl thiab emerald tau ua los ntawm Fab Kis kws tshuaj Walkerin hauv xyoo 1798.
Nrhiav.
Nyob rau xyoo 1828, German chemist Willer thiab Fabkis chemist Bissy siv hlau potassium los txo cov hlau molten feem.
Melted beryllium chloride yields ntshiab beryllium.
Nws lub npe Askiv muaj npe tom qab Weller.
Cov ntsiab lus ntawm beryllium nyob rau hauv lub ntiaj teb crust yog 0.001%, thiab cov minerals tseem ceeb yog beryl, beryllium thiab chrysoberyl.
pob zeb.
Ntuj beryllium muaj peb isotopes:
Beryllium 7, Beryllium 8, Beryllium 10.
2) Lub cev, tshuaj lom neeg thiab cov khoom cia ntawm beryllium Beryllium yog cov hlau grey hlau;melting point yog 1283C,
Boiling point 2970C, ceev 1.85 g / cm, beryllium ion radius 0.31 angstroms, ntau tshaj li lwm yam kub
Lub genus yog me me thiab thermally ruaj khov.
Cov ntsiab lus ntawm beryllium nyob rau hauv lub ntiaj teb crust yog 0.001%, thiab cov minerals tseem ceeb yog beryl.
(3BeOAl2O36SiO2), silicon beryllium (2BeOSiO2) thiab txhuas beryllium (BeOAl2O3).
Minerals muaj beryllium - emerald, tseem hu ua emerald, emerald ntsuab thiab crystal ntshiab, dazzling, yog cov khoom muaj nqis.
Treasures nyob rau hauv pob zeb.
Nws muaj ib qho tseem ceeb tsis tshua muaj hlau jujube beryllium.
Lo lus Greek rau beryllium txhais tau tias emerald.
Emerald yog ib qho txawv ntawm beryl ore.
Beryllium yog tshuaj lom neeg thiab tuaj yeem tsim cov txheej txheej oxide tiv thaiv, txawm tias kub liab
Beryllium kuj tseem ruaj khov hauv huab cua.
