Bariumyintsimbi enzima. Iintsimbi ezinzima zibhekisela kwiintsimbi ezinobunzima obuthile obukhulu kuno-4 ukuya ku-5, kwaye ubunzima obuthile be-barium bu malunga ne-7 okanye i-8, ngoko ke i-barium yintsimbi enzima. Iikhompawundi ze-Barium zisetyenziselwa ukwenza umbala oluhlaza kwizinto zomlilo, kwaye i-barium yensimbi ingasetyenziselwa njenge-arhente yokukhupha i-degassing ukususa i-gas trace kwiityhubhu ze-vacuum kunye neetyhubhu ze-cathode ray, kunye ne-agent ye-degassing yokucoca isinyithi.
1 Ngaba i-barium yintsimbi enzima?I-Barium yintsimbi enzima. Isizathu: Isinyithi esinzima sibhekisela kwisinyithi esinobunzima obuthile obukhulu kuno-4 ukuya kwi-5, kunye nobunzima obuthile be-barium malunga ne-7 okanye i-8, ngoko ke i-barium yintsimbi enzima. Intshayelelo kwi-barium: I-Barium yinto esebenzayo kwi-alkaline yomhlaba. Yintsimbi ethambileyo yomhlaba yealkaline kunye nokukhazimla okumhlophe okwesilivere. Iimpawu zeekhemikhali zisebenza kakhulu, kwaye i-barium ayizange ifumaneke kwindalo. Iiminerali eziqhelekileyo ze-barium kwindalo ziyi-barium sulfate kunye ne-barium carbonate, zombini ezo zinganyibilikiyo emanzini. Ukusetyenziswa kwe-barium: Iikhompawundi ze-Barium zisetyenziselwa ukwenza uhlaza kwii-fireworks, kunyeintsimbi ye-bariumingasetyenziselwa njenge-arhente yokukhupha i-degassing yokususa i-gases yokulandelela kwiityhubhu ze-vacuum kunye neetyhubhu ze-cathode ray, kunye ne-agent ye-degassing yokucoca isinyithi.
2 Yintoni usetyenziso lwebharium? Bariumsisiqalelo sekhemikhali esinophawu lwekhemikhali ethi Ba. I-Barium ineendlela ezininzi zokusetyenziswa, kwaye ezi zilandelayo zezinye zeendlela eziqhelekileyo zokusetyenziswa:
1. Iikhompawundi zeBarium zisetyenziswa njengezinto eziluhlaza kunye nezongezo kwishishini. Ngokomzekelo, iikhompawundi ze-barium zingasetyenziselwa ukwenza i-phosphors yokukhanyisa, i-flame agents, izongezo kunye ne-catalysts.
2. I-Barium ingasetyenziselwa ukwenza iibhubhu ze-X-ray, ezisetyenziswa ngokubanzi kwiinkalo zonyango kunye nezoshishino. Umbhobho we-X-reyi sisixhobo esivelisa ii-X-reyi zokuxilonga kunye nokufumanisa izicelo.
3. Iglasi ye-Barium-lead glass isetyenziswa ngokuqhelekileyo i-optical glass material, ehlala isetyenziselwa ukwenza izixhobo zokukhanya, iiteleskopu, kunye ne-microscopic lens, njl.
4. I-Barium isetyenziswa njenge-additive and alloy component ekwenzeni ibhetri. Inokuphucula ukusebenza kwebhetri kunye nokugcina amandla.
5. Iikhompawundi zeBarium zikwasetyenziselwa ukwenza iimveliso ezifana nezibulali-zinambuzane, iiseramikhi, neeteyiphu zemagnethi.
6. Iikhompawundi ze-Barium zingasetyenziselwa ukulawula izinambuzane kunye nokhula kwi-lawn kunye ne-orchards.Nceda uqaphele ukuba i-barium yinto enobuthi, ngoko kufuneka uqaphele xa usebenzisa kunye nokuphatha i-barium compounds, kwaye ulandele amanyathelo okhuseleko afanelekileyo kunye nezenzo ezizinzileyo.
3 Ibarium ion ihamba ngantoni?I-Barium ion inyuka nge-carbonate ion, i-sulfate ion, kunye ne-sulfite ion. I-Barium yintsimbi yealkaline yomhlaba, i-element kwithuba lesithandathu leqela le-IIA kwitafile ye-periodic, into esebenzayo phakathi kwesinyithi somhlaba we-alkaline, kunye nesinyithi esithambileyo somhlaba esine-luster emhlophe esiliva. I-barium ayizange ifumaneke kwindalo. Iiminerali eziqhelekileyo ze-barium kwindalo ziyi-barite (i-barium sulfate) kunye ne-witherite (i-barium carbonate), zombini ezo zinganyibilikiyo emanzini. I-Barium yaqinisekiswa njengento entsha ngo-1774, kodwa ayizange ihlelwe njengentsimbi yentsimbi de kube kamsinya emva kokuveliswa kwe-electrolysis ngo-1808. ukutshisa. Iityuwa zeBarium zisetyenziswa njengemibala emhlophe ekumgangatho ophezulu. I-Metallic barium yi-deoxidizer egqwesileyo ngexesha lokucocwa kobhedu: isidlo (indlela yokuxilonga izifo ezithile ze-esophageal kunye nesisu. Emva kokuba isigulane sithatha i-barium sulfate, i-X-ray fluoroscopy okanye ifilimu isetyenziswa) .Ibengezela kancinci kwaye i-ductile. Uxinaniso 3.51 g/cm3. Indawo yokunyibilika 725℃. Indawo yokubilisa 1640℃. Valence +2. Amandla e-ionization 5.212 electron volts. Iimpawu zekhemikhali ziyasebenza kwaye zinokusabela ngobuninzi obungezizo iintsimbi. Ukutshisa kwiqondo lokushisa eliphezulu kunye ne-oksijini kuya kuvelisa i-barium peroxide. I-oxidized ngokulula kwaye inokusabela ngamanzi ukwenza i-hydroxide kunye ne-hydrogen. Iyanyibilika kwiasidi ukwenza iityuwa. Iityuwa zeBarium zinetyhefu ngaphandle kwe-barium sulfate. Umyalelo wokusebenza kwesinyithi uphakathi kwepotassium kunye nesodium.
