Bariumndi heavy metal. Zitsulo zolemera zimatanthawuza zitsulo zokhala ndi mphamvu yokoka yaikulu kuposa 4 mpaka 5, pamene barium ili ndi mphamvu yokoka pafupifupi 7 kapena 8, kotero barium ndi chitsulo cholemera. Mankhwala a Barium amagwiritsidwa ntchito popanga zobiriwira muzozimitsa moto, ndipo barium yachitsulo ingagwiritsidwe ntchito ngati degassing wothandizira kuchotsa mpweya kuchokera ku machubu a vacuum ndi machubu a cathode ray, komanso degassing wothandizira zitsulo zoyenga.
Kodi barium ndi heavy metal?
Barium ndi chitsulo cholemera.
Chifukwa: Zitsulo zolemera zimatanthawuza zitsulo zokhala ndi mphamvu yokoka yaikulu kuposa 4 mpaka 5, pamene barium ili ndi mphamvu yokoka pafupifupi 7 kapena 8, kotero barium ndi heavy metal.
Mau oyamba a Barium: Barium ndi chinthu chogwira ntchito mu zitsulo zamchere zamchere, chitsulo chofewa chamchere chapadziko lapansi chokhala ndi kuwala koyera kwasiliva. Mankhwalawa amagwira ntchito kwambiri, ndipo barium elemental sinapezekepo m'chilengedwe. Mchere wambiri wa barium m'chilengedwe ndi barium sulfate ndi barium carbonate, zonse zomwe sizisungunuka m'madzi.
Kugwiritsa ntchito barium: Mankhwala a Barium amagwiritsidwa ntchito popanga zobiriwira pamoto, ndizitsulo za bariumangagwiritsidwe ntchito ngati degassing wothandizira kuchotsa trace mipweya machubu vacuum ndi cathode ray machubu, komanso degassing wothandizila kuyenga zitsulo.
Kodi kugwiritsa ntchito barium ndi chiyani?
Barium ndi mankhwala omwe ali ndi chizindikiro cha mankhwala Ba.
Barium ili ndi ntchito zambiri, zina mwazo ndizofala:
1 Mankhwala a Barium amagwiritsidwa ntchito ngati zopangira komanso zowonjezera m'makampani. Mwachitsanzo, mankhwala a barium angagwiritsidwe ntchito popanga ma phosphor owunikira, zoletsa moto, zowonjezera, ndi zopangira.
2. Barium angagwiritsidwe ntchito kupanga machubu a X-ray ndipo amagwiritsidwa ntchito kwambiri m'madera azachipatala ndi mafakitale. X-ray chubu ndi chipangizo chomwe chimapanga ma X-ray kuti azindikire ndi kuyesa ntchito.
3, galasi lotsogolera la Barium ndi chinthu chomwe chimagwiritsidwa ntchito kwambiri popanga zida zowonera, makina oonera zinthu zakuthambo, ndi magalasi owoneka bwino.
4, Barium imagwiritsidwa ntchito ngati chowonjezera ndi aloyi popanga batri. Ikhoza kupititsa patsogolo ntchito ndi kusungirako mphamvu kwa mabatire.
5. Mankhwala a barium amagwiritsidwanso ntchito popanga zinthu monga mankhwala ophera tizilombo, zoumba, ndi matepi a maginito. Mankhwala a Barium amathanso kugwiritsidwa ntchito polimbana ndi tizirombo ndi udzu mu kapinga ndi m'minda ya zipatso.
Chonde dziwani kuti barium ndi chinthu chapoizoni, chifukwa chake kusamala kuyenera kuchitidwa mukamagwiritsa ntchito ndikugwiritsa ntchito mankhwala a barium, ndipo njira zodzitetezera ziyenera kutsatiridwa.
Makhalidwe a barium
Barium ndi chinthu chachitsulo, choyera chasiliva, chokhala ndi lawi lachikasu lobiriwira likatenthedwa. Mchere wa Barium umagwiritsidwa ntchito ngati pigment yoyera. Chitsulo cha Barium ndi deoxidizer yabwino kwambiri yoyenga mkuwa: njira yodziwira matenda ena am'mimba ndi am'mimba, pomwe odwala amatenga barium sulfate ndikudutsa X-ray fluoroscopy kapena kujambula. Pang'ono glossy, ndi extensibility. Kachulukidwe 3. 51 magalamu pa kiyubiki centimita. Malo osungunuka 725 ℃. Malo otentha 1640 ℃. Valence +2. Ionization mphamvu 5. 212 ma electron volts. Mankhwalawa ndi ogwira ntchito ndipo amatha kuchitapo kanthu ndi zinthu zambiri zomwe sizitsulo. Akatenthedwa pa kutentha kwambiri komanso mu oxygen, barium peroxide imapangidwa. Easy oxidize, wokhoza kuchitapo kanthu ndi madzi kupanga ma hydroxides ndi haidrojeni; Sungunulani mu asidi ndikupanga mchere. Mchere wa Barium ndi poizoni kupatula barium sulfate. Dongosolo la ntchito zachitsulo liri pakati pa potaziyamu ndi sodium.
Titha kupereka 99-99.5% min kuyera kwambirizitsulo za barium,mwalandilidwa kuti mutitumizire kufunsa.
