I-Bariumiyinsimbi enzima. Izinsimbi ezisindayo zibhekisela ezinsimbi ezinamandla adonsela phansi athile angaphezu kuka-4 kuya ku-5, futhi amandla adonsela phansi e-barium acishe abe ngu-7 noma 8, ngakho i-barium iyinsimbi esindayo. Ama-Barium compounds asetshenziselwa ukwenza umbala oluhlaza eziqhumeni zomlilo, futhi i-metallic barium ingasetshenziswa njenge-ejenti yokukhipha umoya ukuze kukhishwe ama-trace gases kumashubhu e-vacuum namashubhu e-cathode ray, nanjenge-ejenti yokukhipha umoya yokucwenga izinsimbi.
1 Ingabe i-barium iyinsimbi enzima?I-Barium iyinsimbi enzima. Isizathu: Izinsimbi ezinzima zibhekisela ezinsimbi ezinamandla adonsela phansi athile angaphezu kuka-4 kuya ku-5, futhi amandla adonsela phansi e-barium acishe abe ngu-7 noma 8, ngakho i-barium iyinsimbi esindayo. Isingeniso se-barium: I-Barium iyisici esisebenzayo ezinsimbi zomhlaba ezine-alkali. Kuyinsimbi yomhlaba ene-alkaline ethambile enombala osiliva ocwebezelayo. Izakhiwo zamakhemikhali zisebenza kakhulu, futhi i-barium ayikaze itholakale emvelweni. Amaminerali ajwayelekile kakhulu e-barium ngokwemvelo yi-barium sulfate ne-barium carbonate, kokubili okungancibiliki emanzini. Ukusetshenziswa kwe-barium: Izinhlanganisela ze-barium zisetshenziselwa ukwenza okuluhlaza eziqhumeni, 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.
2 Yiziphi ukusetshenziswa kwe-barium? I-Bariumisici samakhemikhali esinophawu lwamakhemikhali u-Ba. I-Barium inokusetshenziswa okuningi, futhi okulandelayo okunye ukusetshenziswa okuvamile:
1. Izinhlanganisela ze-barium zisetshenziswa njengezinto ezingavuthiwe nezithasiselo embonini. Isibonelo, ama-barium compounds angasetshenziswa ukwenza ama-phosphors okukhanyisa, ama-flame agents, izithasiselo kanye nama-catalysts.
2. I-Barium ingasetshenziswa ukwenza amashubhu e-X-ray, asetshenziswa kakhulu emkhakheni wezokwelapha nezimboni. Ishubhu ye-X-ray iyithuluzi elikhiqiza ama-X-ray ukuze kusetshenziswe ukuxilonga nokuhlonza.
3. Ingilazi ye-Barium-lead iyinto evame ukusetshenziswa yengilazi ebonakalayo, evame ukusetshenziselwa ukwenza amathuluzi okubona, izibonakude, namalensi amancane, njll.
4. I-Barium isetshenziswa njengesengezo kanye nengxenye yealloy ekukhiqizeni ibhethri. Ingathuthukisa ukusebenza kwebhethri futhi igcine amandla.
5. Izinhlanganisela ze-barium nazo zisetshenziselwa ukwenza imikhiqizo efana nezibulala-zinambuzane, izitsha zobumba, namakhasethi kazibuthe.
6. Ama-Barium compounds angasetshenziswa futhi ekulawuleni izinambuzane kanye nokhula otshanini nasezinsimini zezithelo.Sicela uqaphele ukuthi i-barium iyinto enobuthi, ngakho-ke udinga ukuqaphela lapho usebenzisa futhi uphatha ama-barium compounds, futhi ulandele izinyathelo ezifanele zokuphepha kanye nemikhuba eqhubekayo.
3 Ngabe i-barium ion igxuma ngani?Ama-ion e-barium agcwala ama-ion e-carbonate, ama-ion e-sulfate, nama-ion e-sulfite. I-Barium iyingxenye yensimbi ye-alkaline yomhlaba, isakhi senkathi yesithupha yeqembu le-IIA kuthebula le-periodic, i-elementi esebenzayo phakathi kwezinsimbi zomhlaba ezine-alkaline, kanye nensimbi ethambile yomhlaba ene-alkaline ecwebezelayo emhlophe-siliva.Ngenxa yokuthi i-barium isebenza kakhulu ngamakhemikhali, i-barium ayikaze itholakale emvelweni. Amaminerali ajwayelekile kakhulu e-barium ngokwemvelo yi-barite (i-barium sulfate) ne-witherite (i-barium carbonate), womabili angancibiliki emanzini. I-Barium yaqinisekiswa njengento entsha ngo-1774, kodwa ayizange ihlukaniswe njenge-metallic element kwaze kwaba ngemva nje kokusungulwa kwe-electrolysis ngo-1808. ukuvutha. Usawoti we-Barium usetshenziswa njengezingulube ezimhlophe ezisezingeni eliphakeme. I-Metallic barium iyi-deoxidizer enhle kakhulu ngesikhathi sokucwenga ithusi: ukudla (indlela yokuxilonga izifo ezithile ze-esophageal kanye ne-gastrointestinal. Ngemva kokuba isiguli sithatha i-barium sulfate, i-X-ray fluoroscopy noma ifilimu isetshenziswa) .Icwebezela kancane futhi i-ductile. Ukuminyana 3.51 g/cm3. Iphoyinti lokuncibilika 725 ℃. Indawo yokubilisa 1640 ℃. I-Valence +2. Amandla e-ionization 5.212 electron volts. Izakhiwo zamakhemikhali ziyasebenza impela futhi zingasebenza neziningi ezingezona izinsimbi. Ukushisa ngokushisa okuphezulu kanye ne-oxygen kuzokhiqiza i-barium peroxide. I-oxidized kalula futhi ingasabela ngamanzi ukuze yakhe i-hydroxide ne-hydrogen. Iyancibilika ku-asidi ukwenza usawoti. Usawoti we-Barium unobuthi ngaphandle kwe-barium sulfate. Uhlelo lokusebenza lwensimbi luphakathi kwe-potassium ne-sodium.
