Bariumisimbi inorema. Heavy metals inoreva simbi dzine giravhiti chaiyo yakakura kupfuura 4 kusvika 5, uye iyo chaiyo gravity yebarium inenge 7 kana 8, saka barium isimbi inorema. Mishonga yeBarium inoshandiswa kugadzira ruvara rwegirinhi mumafireworks, uye metallic barium inogona kushandiswa seanobvisa gasi kubvisa trace gasi muvacuum chubhu uye cathode ray machubhu, uye seanobvisa gassing ekunatsa simbi.
1 Barium isimbi inorema here?Barium isimbi inorema. Chikonzero: Masimbi anorema anoreva simbi dzine giravhiti chaiyo yakakura kupfuura 4 kusvika 5, uye iyo chaiyo giravhiti ye barium inenge 7 kana 8, saka barium isimbi inorema. Nhanganyaya kune barium: Barium chinhu chinoshanda mu alkaline pasi simbi. Isimbi yepasi ine alkaline yakapfava ine sirivheri chena inopenya. Izvo zvemakemikari zvinhu zvinoshanda zvakanyanya, uye barium haina kumbowanikwa mune zvakasikwa. Maminerari akajairika emu barium muzvisikwa ndeye barium sulfate uye barium carbonate, ese ari maviri asinganyungudika mumvura. Kushandiswa kweBarium: Mishonga yeBarium inoshandiswa kugadzira girini mumafireworks, uyebarium simbiinogona kushandiswa seanobvisa gasi kubvisa gasi rekutsvaga muvacuum chubhu uye cathode ray chubhu, uye degassing agent yekunatsa simbi.
2 Chii chinoshandiswa nebarium? Bariumchinhu chemakemikari chine chiratidzo chemakemikari Ba. Barium ine zvakawanda zvinoshandiswa, uye zvinotevera ndezvimwe zvezvinowanzoshandiswa:
1. Mishonga yeBarium inoshandiswa sezvinhu zvakasvibiswa uye zvinowedzera mumhizha. Semuyenzaniso, barium makomboni anogona kushandiswa kugadzira mwenje phosphors, flame agents, additives uye catalysts.
2. Barium inogona kushandiswa kugadzira X-ray tubes, iyo inoshandiswa zvakanyanya mune zvekurapa uye maindasitiri. X-ray chubhu mudziyo unogadzira X-rays yekuongorora uye kuona maapplication.
3. Barium-lead girazi chinhu chinowanzoshandiswa optical glass material, chinowanzo shandiswa kugadzira zviridzwa zvemaziso, telescopes, uye microscopic lenses, nezvimwewo.
4. Barium inoshandiswa sekuwedzera uye alloy chikamu mukugadzirwa kwebhatiri. Inogona kuvandudza kushanda kwebhatiri uye kuchengetedza simba.
5. Mishonga yeBarium inoshandiswawo kugadzira zvinhu zvakadai semishonga yezvipembenene, makeramiki, uye magineti matepi.
6. Mishonga yeBarium inogonawo kushandiswa kudzora tupukanana nemasora muuswa nemiti yemichero.Ndapota cherechedzai kuti barium chinhu chine chepfu, saka unofanira kungwarira paunenge uchishandisa uye kubata barium compounds, uye kutevera nzira dzakakodzera dzekuchengetedza uye maitiro anochengetedza.
3 Barium ion inokwira nei?Barium ions inonaya ne carbonate ions, sulfate ions, uye sulfite ions. Barium is alkaline earth metal element, chinhu chiri muchikamu chechitanhatu cheboka IIA mu periodic table, chinhu chinoshanda pakati pe alkaline earth metals, uye soft alkaline earth metal ine silvery-white luster.Nekuti barium ikemikari inoshanda zvikuru, barium haina kumbobvira yawanikwa mune zvakasikwa. Maminerari anonyanya kuzivikanwa emubarium muzvisikwa ndeye barite (barium sulfate) uye witherite (barium carbonate), ose ari maviri asinganyungudike mumvura. Barium yakasimbiswa sechinhu chitsva muna 1774, asi haina kuverengerwa sesimbi kusvika nguva pfupi mushure mekugadzirwa kwe electrolysis muna 1808. kutsva. Barium salts inoshandiswa seyepamusoro-giredhi chena pigments. Metallic barium yakanakisa deoxidizer panguva yekunatsa mhangura: kudya (nzira yekuongorora zvimwe zvirwere zvegurokuro uye zvomudumbu. Mushure mekunge murwere atora barium sulfate, X-ray fluoroscopy kana firimu inoshandiswa) .Inopenya zvishoma uye ductile. Density 3.51 g/cm3. Melting point 725 ℃. Boiling point 1640 ℃. Valence +2. Ionization simba 5.212 electron volts. Iyo kemikari zvivakwa inoshanda chaizvo uye inogona kuita neakawanda asiri masimbi. Kupisa pakupisa kukuru uye muokisijeni kunobudisa barium peroxide. Inogadziriswa nyore nyore uye inogona kuita nemvura kuti igadzire hydroxide uye hydrogen. Inonyungudika muasidhi kuita munyu. Barium salt ine chepfu kunze kwebarium sulfate. Iyo simbi yekuita order iri pakati pe potassium ne sodium.
