I-Bariumiyinsimbi enzima. Izinsimbi ezinzima zibhekisela ezinsimbi ezinamandla adonsela phansi athile angaphezu kuka-4 kuya ku-5, kuyilapho i-barium inomthamo othize ongaba ngu-7 noma 8, ngakho-ke i-barium iyinsimbi esindayo. I-Barium compounds isetshenziselwa ukukhiqiza okuluhlaza eziqhumeni zomlilo, futhi i-barium yensimbi ingasetshenziswa njenge-ejenti yokukhipha umoya ukuze kukhishwe ama-trace gases kumashubhu e-vacuum namashubhu e-cathode ray, kanye ne-ejenti yokukhipha umoya yokucwenga izinsimbi.
Ingabe i-barium iyinsimbi enzima?
I-Barium iyinsimbi enzima.
Isizathu: Izinsimbi ezinzima zibhekisela ezinsimbi ezinamandla adonsela phansi athile angaphezu kuka-4 kuya ku-5, kuyilapho i-barium inomthamo othize ongaba ngu-7 noma 8, ngakho-ke i-barium iyinsimbi esindayo.
Isingeniso se-Barium: I-Barium iyisici esisebenzayo ezinsimbi zomhlaba ezine-alkaline, insimbi ethambile yomhlaba ene-alkaline ecwebezelayo emhlophe. Izakhiwo zamakhemikhali zisebenza kakhulu, futhi i-barium elemental ayikaze itholakale emvelweni. Amaminerali ajwayelekile kakhulu e-barium ngokwemvelo yi-barium sulfate ne-barium carbonate, kokubili okungancibiliki emanzini.
Ukusetshenziswa kwe-barium: Amakhemikhali e-barium asetshenziselwa ukukhiqiza okuluhlaza eziqhumeni zomlilo, kanyeinsimbi ye-bariumingasetshenziswa njenge-ejenti yokukhipha umoya ukuze isuse ama-trace gases kumashubhu e-vacuum namashubhu e-cathode ray, kanye ne-ejenti yokukhipha umoya yokucwenga izinsimbi.
Kuyini ukusetshenziswa kwe-barium?
I-Barium iyisici samakhemikhali esinophawu lwamakhemikhali u-Ba.
I-Barium inokusetshenziswa okuningi, okunye okujwayelekile:
1 Izinhlanganisela ze-Barium zisetshenziswa njengezinto ezingavuthiwe nezithasiselo embonini. Isibonelo, ama-barium compounds angasetshenziswa ukwenza ama-phosphor okukhanyisa, ama-flame retardants, izithasiselo, kanye nama-catalysts.
2. I-Barium ingasetshenziswa ukwenza amashubhu e-X-ray futhi isetshenziswa kakhulu emikhakheni yezokwelapha nezimboni. Ishubhu ye-X-ray iyithuluzi elikhiqiza ama-X-reyi ohlelo lokuxilonga nokuhlola.
3，Ingilazi eholayo ye-Barium yinto evame ukusetshenziswa yengilazi ebonakalayo, evame ukusetshenziswa ekukhiqizeni amathuluzi okubona, izibonakude, namalensi amancane.
4, I-Barium isetshenziswa njengesengezo kanye nengxenye ye-alloy ekukhiqizeni ibhethri. Ingathuthukisa ukusebenza nokugcinwa kwamandla kwamabhethri.
5. Izithako ze-barium nazo zisetshenziselwa ukwenza imikhiqizo efana nezibulala-zinambuzane, izitsha zobumba, namateyipu kazibuthe. I-Barium compounds ingasetshenziswa futhi ukulawula izinambuzane nokhula otshanini nasezinsimini zezithelo.
Sicela uqaphele ukuthi i-barium iyisici esinobuthi, ngakho-ke kufanele kuqashelwe uma usebenzisa futhi uphatha izinhlanganisela ze-barium, futhi izinyathelo zokuphepha ezihambisanayo kanye nemikhuba yokusimama kufanele ilandelwe.
Izakhiwo ze-barium
I-Barium iyingxenye yensimbi, emhlophe esiliva ngombala, nelangabi eliphuzi eliluhlaza lapho lishiswa. Usawoti we-Barium usetshenziswa njengezingulube ezimhlophe ezithuthukisiwe. I-Barium metal iyi-deoxidizer enhle kakhulu yokucwenga ithusi: indlela yokuxilonga yezifo ezithile zomphimbo kanye nezamathumbu, lapho iziguli zithatha i-barium sulfate futhi zenze i-X-ray fluoroscopy noma imaging. Icwebezela kancane, nokunwebeka. Ukuminyana 3. 51 amagremu cubic centimeter ngayinye. Iphoyinti lokuncibilika 725 ℃. Iphuzu lokubilisa 1640 ℃. I-Valence+2. Amandla e-ionization 5. 212 ama-electron volts. Izakhiwo zamakhemikhali ziyasebenza impela futhi zingasebenza neziningi ezingezona izinsimbi. Uma ushiswa emazingeni okushisa aphezulu kanye ne-oxygen, i-barium peroxide ikhiqizwa. Kulula ukwenza i-oxidize, ekwazi ukusabela emanzini ukukhiqiza ama-hydroxides ne-hydrogen; Chaza ku-asidi bese wenza usawoti. Usawoti we-Barium unobuthi ngaphandle kwe-barium sulfate. Ukuhleleka komsebenzi wensimbi kuphakathi kwe-potassium ne-sodium.
Singahlinzeka ngo-99-99.5% min ukuhlanzeka okuphezuluinsimbi ye-barium,wamukelekile ukusithumela uphenyo.
