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, 'me matla a khoheli a barium a ka ba 7 kapa 8, kahoo barium ke tšepe e boima. Lik'hemik'hale tsa Barium li sebelisetsoa ho etsa 'mala o motala ka li-fireworks,' me metallic barium e ka sebelisoa e le sesebelisoa sa ho tlosa likhase ho tlosa likhase tsa vacuum le li-tubes tsa cathode ray, hape e le moemeli oa degassing bakeng sa ho hloekisa tšepe.
1 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 a fetang 4 ho isa ho 5, 'me matla a khoheli a barium a ka bang 7 kapa 8, kahoo barium ke tšepe e boima. Selelekela ho barium: Barium ke ntho e sebetsang ka har'a tšepe ea lefatše ea alkaline. Ke tšepe e bonolo ea alkaline ea lefats'e e nang le bosoeu bo bosoeu. Lintho tsa lik'hemik'hale li sebetsa haholo, 'me barium 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 etsa botala ka li-fireworks, letšepe ea bariume ka sebelisoa e le sesebelisoa sa degassing ho tlosa likhase tsa trace ka har'a li-tubes tsa vacuum le li-tubes tsa cathode ray, le sesebelisoa sa degassing bakeng sa ho hloekisa tšepe.
2 Litšebeliso tsa barium ke life? Bariumke ntho ea lik'hemik'hale e nang le letšoao la lik'hemik'hale Ba. Barium e na le litšebeliso tse ngata, 'me tse latelang ke tse ling tsa litšebeliso tse tloaelehileng:
1. Lik'hemik'hale tsa Barium li 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 agents, li-additives le li-catalysts.
2. Barium e ka sebelisoa ho etsa li-tubes tsa X-ray, tse sebelisoang haholo litabeng tsa bongaka le tsa indasteri. X-ray tube ke sesebelisoa se hlahisang X-ray bakeng sa lits'ebetso tsa tlhahlobo le ho lemoha.
3. Khalase ea barium-lead ke ntho e sebelisoang ka tloaelo ea khalase ea optical, hangata e sebelisetsoang ho etsa lisebelisoa tsa optical, telescopes, le lilense tse nyenyane haholo, joalo-joalo.
4. Barium e sebelisoa e le motsoako oa motsoako le motsoako oa ho etsa betri. E ka ntlafatsa ts'ebetso ea betri le ho boloka matla.
5. Metsoako ea barium e boetse e sebelisetsoa ho etsa lihlahisoa tse kang chefo e bolaeang likokoanyana, lirafshoa le litheipi tsa makenete.
6. Metsoako ea Barium e ka boela ea sebelisoa ho laola likokoanyana le mofoka mohloeng le lirapa tsa lifate tsa litholoana.Ka kopo hlokomela hore barium ke ntho e chefo, kahoo u lokela ho ba hlokolosi ha u sebelisa le ho sebetsana le metsoako ea barium, 'me u latele mehato e nepahetseng ea tšireletso le mekhoa e tsitsitseng.
3 Barium ion e phahama ka eng?Li-ion tsa barium li na le li-ion tsa carbonate, li-ion tsa sulfate, le li-ion tsa sulfite. Barium ke karolo ea tšepe ea lefatše ea alkaline, e leng karolo ea nako ea botšelela ea sehlopha sa IIA tafoleng ea periodic, ntho e sebetsang har'a litšepe tsa lefatše tsa alkaline, le tšepe e bonolo ea alkaline ea lefats'e e nang le khanya e tšoeu ea silevera. Hobane barium e sebetsa haholo ka lik'hemik'hale. barium ha e e-s'o fumanoe tlhahong. Liminerale tse tloaelehileng ka ho fetisisa tsa barium ka tlhaho ke barite (barium sulfate) le witherite (barium carbonate), tseo ka bobeli li sa keneng metsing. Barium e ile ea tiisoa e le ntho e ncha ka 1774, empa ha ea ka ea khetholloa e le ntho ea tšepe ho fihlela nakoana ka mor'a hore ho qaptjoe electrolysis ka 1808. 4 Properties of barium Barium ke metallic element, silvery white, 'me e ntša lelakabe le mosehla o motala. tukang. Matsoai a Barium a sebelisoa e le li-pigment tse tšoeu tsa boemo bo holimo. Metallic barium ke deoxidizer e babatsehang nakong ea ho hloekisa koporo: lijo (mokhoa oa ho hlahloba mafu a itseng a 'metso le a mala. Ka mor'a hore mokuli a nke barium sulfate, X-ray fluoroscopy kapa filimi e sebelisoa). Boima ba 3.51 g/cm3. Sebaka se qhibilihang ke 725 ℃. Sebaka se belang 1640 ℃. Valence +2. Matla a ionization 5.212 electron volts. Thepa ea lik'hemik'hale e sebetsa haholo 'me e khona ho sebetsana le boholo ba li-non-metal. Ho chesa ka mocheso o phahameng le ka oksijene ho tla hlahisa barium peroxide. E na le oxidized habonolo 'me e ka itšoara ka metsi ho etsa hydroxide le hydrogen. E qhibiliha ka asiti 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.
