Bariumyintsimbi enzima. Iintsimbi ezinzima zibhekisa kwiintsimbi ezinobunzima obuthile obukhulu kuno-4 ukuya ku-5, ngelixa i-barium inobunzima obuthile obumalunga ne-7 okanye i-8, ngoko ke i-barium yintsimbi enzima. Iikhompawundi ze-Barium zisetyenziselwa ukuvelisa uhlaza kwii-fireworks, kwaye i-barium ye-metallic ingasetyenziselwa njenge-agent ye-degassing ukususa i-gas trace kwi-vacuum tubes kunye ne-cathode ray tubes, kunye ne-agent ye-degassing yokucoca isinyithi.
Ngaba i-barium yintsimbi enzima?
I-Barium yintsimbi enzima.
Isizathu: Isinyithi esinzima sibhekisa kwiintsimbi ezinobunzima obuthile obukhulu kuno-4 ukuya ku-5, ngelixa i-barium inobunzima obuthile malunga ne-7 okanye i-8, ngoko ke i-barium yintsimbi enzima.
Intshayelelo yeBarium: I-Barium yinto esebenzayo kwisinyithi somhlaba we-alkaline, isinyithi esithambileyo se-alkaline yomhlaba kunye ne-luster emhlophe yesilivere. Iimpawu zeekhemikhali zisebenza kakhulu, kwaye i-barium elemental ayizange ifumaneke kwindalo. Iiminerali eziqhelekileyo ze-barium kwindalo ziyi-barium sulfate kunye ne-barium carbonate, zombini ezo zinganyibilikiyo emanzini.
Ukusetyenziswa kwe-barium: I-Barium compounds isetyenziselwa ukuvelisa uhlaza kwii-fireworks, kunyeintsimbi ye-bariuminokusetyenziswa njenge-agent ekhupha i-degassing ukususa i-gas trace kwi-vacuum tubes kunye neetyhubhu ze-cathode ray, kunye ne-agent ye-degassing yokucoca isinyithi.
Yintoni ukufakwa kwe-barium?
I-Barium yikhemikhali yesimboli ye-Ba.
I-Barium ineendlela ezininzi zokusetyenziswa, ezinye zazo eziqhelekileyo:
1 Iikhompawundi zeBarium zisetyenziswa njengezinto eziluhlaza kunye nezongezo kwishishini. Ngokomzekelo, iikhompawundi ze-barium zingasetyenziselwa ukuvelisa i-phosphors yokukhanyisa, i-flame retardants, izongezo, kunye ne-catalysts.
2. I-Barium ingasetyenziselwa ukwenza iityhubhu ze-X-ray kwaye isetyenziswa ngokubanzi kwiinkalo zonyango kunye nezoshishino. Umbhobho we-X-reyi sisixhobo esenza ii-X-reyi zokuxilonga kunye nokuvavanya izicelo.
3，Iglasi ekhokelayo yeBarium yinto eqhelekileyo esetyenziswa kwiglasi ebonakalayo, eqhele ukusetyenziswa kwimveliso yezixhobo zamehlo, iiteleskopu, kunye neelensi ezincinci.
4, I-Barium isetyenziswa njengenxalenye yokudibanisa kunye ne-alloy ekwenzeni ibhetri. Inokuphucula ukusebenza kunye nokugcinwa kwamandla kweebhetri.
5. Iikhompawundi zeBarium zikwasetyenziselwa ukwenza iimveliso ezifana nezitshabalalisi, iiseramikhi, kunye neeteyiphu zemagnethi. Iikhompawundi zeBarium zingasetyenziselwa ukulawula izitshabalalisi kunye nokhula kwingca kunye namabhoma.
Nceda uqaphele ukuba i-barium yinto enobuthi, ngoko kufuneka kulumke xa usebenzisa kunye nokuphatha i-barium compounds, kunye nemilinganiselo yokukhusela ehambelanayo kunye nezenzo zokuzinza kufuneka zilandelwe.
Iimpawu ze-barium
I-Barium yinto yentsimbi, isilivere emhlophe ngombala, kunye nedangatye elityheli eliluhlaza xa litshiswa. Iityuwa zeBarium zisetyenziswa njengeebala ezimhlophe eziphambili. I-Barium metal yi-deoxidizer egqwesileyo yokucoca ubhedu: indlela yokuxilonga kwizifo ezithile ze-esophageal kunye ne-gastrointestinal, apho izigulane zithatha i-barium sulfate kunye ne-X-ray fluoroscopy okanye i-imaging. Ikhazimle kancinci, kunye nokwandiswa. Uxinaniso 3. 51 grams cubic centimeter nganye. Indawo yokunyibilika 725 ℃. Indawo yokubilisa 1640 ℃. Valence+2. Amandla e-ionization 5. 212 electron volts. Iimpawu zekhemikhali ziyasebenza kwaye zinokusebenza ngobuninzi obungezizo isinyithi. Xa utshiswa kumaqondo aphezulu kunye ne-oxygen, i-barium peroxide yenziwa. Kulula ukwenza i-oxidize, ekwaziyo ukusabela ngamanzi ukuvelisa i-hydroxides kunye ne-hydrogen; Ukunyibilika kwi-asidi kwaye wenze iityuwa. Iityuwa zeBarium zinetyhefu ngaphandle kwe-barium sulfate. Umyalelo womsebenzi wesinyithi uphakathi kwe-potassium kunye ne-sodium.
Sinokubonelela nge-99-99.5% min ukucoceka okuphezuluintsimbi ye-barium,wamkelekile ukuba usithumelele umbuzo.
