Bariumisimbi inorema. Heavy metals inoreva simbi dzine giravhiti chaiyo yakakura kudarika 4 kusvika 5, ukuwo barium ine giravhiti chaiyo inosvika 7 kana 8, saka barium isimbi inorema. Mishonga yeBarium inoshandiswa kugadzira green in fireworks, uye metallic barium inogona kushandiswa se degassing agent kubvisa trace gasi kubva kune vacuum tubes uye cathode ray tubes, pamwe ne degassing agent yekunatsa simbi.
Barium isimbi inorema here?
Barium isimbi inorema.
Chikonzero: Masimbi anorema anoreva simbi dzine giravhiti yakakura kupfuura 4 kusvika 5, nepo barium ine simba rinokwevera zvinhu rinosvika pa7 kana 8, saka barium isimbi inorema.
Nhanganyaya yeBarium: Barium chinhu chinoshanda mumasimbi epasi ane alkaline, simbi yepasi ine alkaline yakapfava ine sirivha chena inopenya. Iwo emakemikari zvimiro anoshanda zvakanyanya, uye barium elemental haina kumbobvira yawanikwa mune zvakasikwa. Maminerari akajairika emu barium muzvisikwa ndeye barium sulfate uye barium carbonate, ese ari maviri asinganyungudika mumvura.
Kushandiswa kweBarium: Barium compounds inoshandiswa kugadzira girini mumafireworks, uyebarium simbiinogona kushandiswa seanobvisa gasi kubvisa gasi rekutsvaga kubva kune vacuum tubes uye cathode ray tubes, pamwe chete ne degassing agent yekunatsa simbi.
Chii chinonzi barium?
Barium chinhu chemakemikari chine chiratidzo chemakemikari Ba.
Barium ine akawanda mashandisirwo, mamwe acho akajairika:
1 Barium makomisheni anoshandiswa seyakagadzirwa zvinhu uye zvinowedzera muindasitiri. Semuenzaniso, barium makomisheni anogona kushandiswa kugadzira phosphors yekuvhenekesa, zvinodzoreredza murazvo, zvinowedzera, uye zvinokonzeresa.
2. Barium inogona kushandiswa kugadzira X-ray tubes uye inoshandiswa zvakanyanya mune zvekurapa uye maindasitiri. Iyo X-ray chubhu mudziyo unogadzira X-rays yekuongorora uye yekuyedza maapplication.
3，Barium lead girazi inowanzoshandiswa mukugadzirwa kwemidziyo yekuona, teresikopu, uye malenzi asingaoneki.
4, Barium inoshandiswa sekuwedzera uye alloy chikamu mukugadzira bhatiri. Inogona kuvandudza kushanda uye kuchengetedza simba kwemabhatiri.
5. Mishonga yeBarium inoshandiswawo kugadzira zvinhu zvakaita semishonga yezvipembenene, maceramics, uye magineti matepi. Mishonga yeBarium inogonawo kushandiswa kudzora tupukanana nemasora mumakwenzi neminda yemichero.
Ndapota cherechedza kuti barium chinhu chine chepfu, saka kuchenjerera kunofanira kushandiswa paunenge uchishandisa uye kubata barium makomputa, uye anowirirana ekuchengetedza maitiro uye kusimudzira maitiro kunofanirwa kuteverwa.
Zvinhu zve barium
Barium isimbi yesimbi, sirivha chena muruvara, ine yero yegirini murazvo kana yapiswa. Barium salts inoshandiswa seyepamusoro machena pigment. Barium simbi yakanakisa deoxidizer yekunatsa mhangura: nzira yekuongorora yeimwe esophageal uye gastrointestinal zvirwere, apo varwere vanotora barium sulfate uye vanoenda X-ray fluoroscopy kana imaging. Zvishoma kupenya, pamwe nekuwedzera. Density 3. 51 magiramu pa cubic centimita. Kunyungudika 725 ℃. Boiling point 1640 ℃. Valence+2. Ionization simba 5. 212 electron volts. Iyo kemikari zvimiro inoshanda uye inogona kuita neakawanda asiri masimbi. Kana yapiswa pakupisa kwakanyanya uye muokisijeni, barium peroxide inogadzirwa. Zviri nyore kuita oxidize, inokwanisa kuita nemvura kugadzira hydroxides uye hydrogen; Dissolve mu acid uye gadzira munyu. Barium salt ine chepfu kunze kwebarium sulfate. Kurongeka kwekuita kwesimbi kuri pakati pe potassium ne sodium.
Tinogona kupa 99-99.5% min kuchena kwakanyanyabarium simbi,tinokugamuchirai kutitumira kubvunza.
