Bariumke tshepe e boima. Limetale tse boima li bua ka litšepe tse nang le matla a khoheli a itseng a fetang 4 ho isa ho 5, athe barium e na le matla a khoheli a ka bang 7 kapa 8, kahoo barium ke tšepe e boima. Lik'hemik'hale tsa Barium li sebelisetsoa ho hlahisa li-fireworks tse tala, 'me barium ea tšepe e ka sebelisoa e le sesebelisoa sa degassing ho tlosa likhase tse tsoang ho li-vacuum tubes le li-tubes tsa cathode ray, hammoho le moemeli oa degassing bakeng sa ho hloekisa tšepe.
Na barium ke tšepe e boima?
Barium ke tšepe e boima.
Lebaka: Limetale tse boima li bua ka litšepe tse nang le matla a khoheli a itseng ho feta 4 ho isa ho 5, athe barium e na le matla a khoheli a ka bang 7 kapa 8, kahoo barium ke tšepe e boima.
Selelekela sa Barium: Barium ke ntho e sebetsang ka har'a tšepe ea lefatše ea alkaline, tšepe e bonolo ea alkaline ea lefats'e e nang le bosoeu ba silevera. Lintho tsa lik'hemik'hale li sebetsa haholo, 'me barium elemental ha e e-s'o fumanoe tlhahong. Liminerale tse tloaelehileng ka ho fetisisa tsa barium ka tlhaho ke barium sulfate le barium carbonate, tseo ka bobeli li sa qhibiliheng metsing.
Tšebeliso ea barium: Metsoako ea Barium e sebelisoa ho hlahisa botala ka li-fireworks, letšepe ea bariume ka sebelisoa e le sesebelisoa sa degassing ho tlosa likhase tsa trace ho li-tubes tsa vacuum le li-tubes tsa cathode ray, hammoho le moemeli oa ho ntša metsi bakeng sa ho hloekisa litšepe.
Tšebeliso ea barium ke eng?
Barium ke ntho ea lik'hemik'hale e nang le letšoao la lik'hemik'hale Ba.
Barium e na le lisebelisoa tse ngata, tse ling tsa tsona li tloaelehile:
1 Metsoako ea Barium e sebelisoa e le lisebelisoa tse tala le li-additives indastering. Ka mohlala, metsoako ea barium e ka sebelisoa ho etsa phosphors e khanyang, li-flame retardants, li-additives le li-catalysts.
2. Barium e ka sebelisoa ho etsa li-tubes tsa X-ray 'me e sebelisoa haholo litabeng tsa bongaka le tsa indasteri. X-ray tube ke sesebelisoa se hlahisang X-ray bakeng sa lits'ebetso tsa tlhahlobo le tlhahlobo.
3，Khalase e etellang pele ea Barium ke ntho e sebelisoang hangata ho etsa lisebelisoa tsa optical, telescopes le lilense tse nyane haholo.
4, Barium e sebelisoa e le motsoako oa motsoako le motsoako oa ho etsa betri. E ka ntlafatsa ts'ebetso le polokelo ea matla ea betri.
5. Metsoako ea Barium e boetse e sebelisetsoa ho etsa lihlahisoa tse kang chefo e bolaeang likokoanyana, lirafshoa le litheipi tsa makenete. Metsoako ea Barium e ka boela ea sebelisoa ho laola likokoanyana le lehola mohloeng le lirapa tsa lifate tsa litholoana.
Ka kopo hlokomela hore barium ke ntho e chefo, kahoo ho lokela ho hlokomeloa ha u sebelisa le ho sebetsana le metsoako ea barium, 'me mehato e ts'oanang ea ts'ireletso le mekhoa ea ts'ebetso e lokela ho lateloa.
Thepa ea barium
Barium ke ntho ea tšepe, 'mala o mosoeu oa silevera, o nang le lelakabe le mosehla o motala ha o chesoa. Matsoai a Barium a sebelisoa e le li-pigment tse tšoeu tse tsoetseng pele. Barium metal ke deoxidizer e babatsehang bakeng sa ho hloekisa koporo: mokhoa oa ho hlahloba mafu a itseng a 'metso le a mala, moo bakuli ba nkang barium sulfate le ho etsa X-ray fluoroscopy kapa imaging. E benyang hanyane, e nang le katoloso. Boima ba 3. 51 grams per cubic centimeter. Sebaka se qhibilihang ke 725 ℃. Sebaka se belang 1640 ℃. Valence+2. Matla a ionization 5. 212 electron volts. Lik'hemik'hale li sebetsa haholo 'me li khona ho sebetsana le litšepe tse ngata tseo e seng tsa tšepe. Ha e chesoa ka mocheso o phahameng le ka oksijene, barium peroxide e hlahisoa. Ho bonolo ho oxidize, e khona ho sebetsana le metsi ho hlahisa hydroxides le hydrogen; Qhibiliha ka acid le ho etsa matsoai. Matsoai a Barium a na le chefo ntle le barium sulfate. Taelo ea ts'ebetso ea tšepe e pakeng tsa potasiamo le sodium.
Re ka fana ka 99-99.5% min bohloeki bo phahamengtšepe ea barium,amohela ho re romella lipotso.
