Element 56: Bariamu

1, Shanduro yekutangaBariamu,
Iyo Alkaline Pasi Pasi pelement, ine Chemical Symbol Ba, iri muboka IIa yenguva yechitanhatu yetanhatu tafura. Iyo yakapfava, sirivha chena yakasarudzika alkaline yepasi simbi uye chinhu chinonyanya kushanda muAlinline Pasi. Iro zita relement rinobva muShoko reChigiriki Beta Alpha (barys), zvinoreva kuti "rinorema".

2, Kuwana Nhoroondo pfupi
Sulfides yeAlkaline Pasi Simbi inoratidza phosphorescence, zvichireva kuti vanoregedza kusimbisa chiedza kwenguva yakati rerima mushure mekuvhenekerwa nechiedza. Barium comalound akatanga kukwezva kutarisa kwevanhu chaizvo nekuda kwehunhu hwani. Muna 1602, shoemaker anonzi Casio Lauro muGuta reBlogena, Italy, yakagochera barisi ine zvinhu zvinopisa uye akawana kuti inogona kufadza mune rima, iyo yakamutsa kufarira kwevadzidzi panguva iyoyo. Gare gare, iyi ibwe rebwe rakanzi Polon uye ruka kufarira kweEuropean makemikist mukuongororwa kwekuongorora. Muna 1774, Sweden Chemist CW SchEele akawana kuti xium auti yaive ivhu rutsva, raakadana "baryta" (ivhu rinorema). Muna 1774, Scheler akatenda kuti ibwe iri raive musanganiswa wevhu nyowani (oxide) uye sarufac acid. Muna 1776, akapa nitrate mune iyi ivhu nyowani kuwana ivhu rakachena (oxide). Muna 1808, British Chemist H. Davy akashandisa Mercury seCathode uye Platinum seAnode kuEkisiyasi Barite (Baso4) kuburitsa Barium Amalgam. Mushure mekuregedza kubvisa mercury, simbi yakadzika kwazvo yakawanikwa uye inotumidzwa izwi mushure mezwi reChigiriki barys (rinorema). Chiratidzo chelement chakaiswa seBA, iyo inonziBariamu.

3, zvivakwa zvemuviri
Bariamuis sirivha chena simbi ine melting point ye725 ° C, inovira point ye 1846 ° C, density of 3.51g / cm3, uye ductility. Iyo huru yeres yeBarium iri barite uye arsenopyrite.

4,Bariamuchinhu chemakemikari chine makemikari zvivakwa.
Chemical Symbol BA, ATOMIC Nhamba 56, ndeyoko nguva yeSyita Iia Boka uye inhengo yeAlinline Pasi. Barium ane chiitiko chikuru chemakemikari uye chinonyanya kushanda pakati peAlkaline Pasi simbi. Kubva pane kugona kugona uye ionization simba, zvinogona kuoneka kuti Bartium ane kuderedzwa kwakasimba. Chaizvoizvo, kana chete uchifunga nezvekurasikirwa kweAyekutanga Electron, Bariamu ane kuderedza kwakasimba mumvura. Nekudaro, zvakanyanyisa kuomesa bariyk yekurasikirwa neyechipiri emagetsi. Naizvozvo, uchifunga nezvezvinhu zvese, kuderedza kweBarium kuchadzikira zvakanyanya. Zvakangodaro, zvakare ndeimwe yemasita anonyanya kushanda mumamiriro ekunze, yechipiri chete kuna Lithium, Cesium, Rubidium, uye Potsium.

5 main main
1). Barium oxide zvishoma nezvishoma oxidues mumhepo kuti aumbe chibhagi calide, iyo iri isina ruvara cubic crystal. Nyura musidhi, svinura muaccount nemvura amonia. Inobata nemvura kuti iite atium hydroxide, iyo ine chepfu. Kana ichinge yapiswa, inoburitsa murazvo wegirini uye unogadzira bharium peroxide.
2). Barium Peroxide Inosangana neSulfutic acid kuti igadzire hydrogen peroxide. Kuita uku kwakavakirwa pachirongwa chekugadzirira hydrogen peroxide mune laboratori.
3). Barium Hydroxide inonyora nemvura kuti ibudise atium hydroxide uye hydrogen gasi. Nekuda kwekudzikira kwekushamisika kweBarium Hydroxide uye isimba racho rakakura, maitiro haana kunyanyisa seyaAlkali simbi, uye iyo yakakonzerwa neardroxide ichavhiringidza maonero. Mari shoma yeCarbon Dioxide inounzwa mumhinduro yekugadzira kabhoni kabhoni yebhoni
4). Amino Bariamu inogona kunyungudika mumvura ambomoni, inoburitsa mhinduro yebhuruu neParamagnetism uye Unitivity, iyo zvinonyatsoita maEkinesi Electrons. Mushure menguva yakareba yekuchengetedza, iyo hydrogen muAmmonia ichaderedzwa kusvika kuHydrogen gasi neAmmonia Electrons
5). Barium Sulfite ndeyechena crystal kana poda, ine chepfu, zvishoma zvinyoro-nyoro mumvura, uye zvishoma nezvishoma oxidized muBarium Sulfate kana akaiswa mumhepo. Nyungudika mukusina oxidizing yakasimba acids yakadai se hydrochloric acid kuti igadzire sarufa digren dioxide gasi ine unonhuwira. Paunenge uchisangana ne oxidizing acids akadai seDilute nitric acid, inogona kushandurwa muBarium Sulfate.
6). Barium Sulfate ine nzvimbo dzakagadzikana chemakemikari, uye chikamu cheBarium Sulfate zvakanyungudutswa mumvura zvakazara Barium Sulfate ndeye kusanzwisisika muDilute Nitric acid. Inonyanya kushandiswa segastrointestinal kusiyanisa mumiririri.
Barium kabhoni ane chepfu uye anenge achida kushaiwa mvura inotonhora. Inobata neSodium Sulfate kuti igadzire yakanyanya kuchena chena yeBarium Sulfate

6, minda yekushandisa
1. Izvo zvinoshandiswa kune zvinangwa zveindasitiri mukugadzirwa kweBarium Salts, Alloys, Fireworks, Etlear Entworks, etc. Iri zvakare deoxidizer yekunatsa mhangura. Inoshandiswa zvakanyanya muAlloys, kusanganisira kutungamira, Calcium, magnesium, Sodium, Lithium, Aluminium, uye Nickel Alloys. Metal Mobil inogona kushandiswa seyenzizi yekubvisa magasi anoteedzera kubva pacuum machubhu uye cathode ray machubhu, pamwe nemunyori wedhiza ekunatsa simbi. Barium Nitrate yakasanganiswa ne potasium chlorate, magnesium poda, uye rosin inogona kushandiswa kugadzira chiratidzo chemasaini uye fireworks. Solullable Barium Compound inowanzo shandiswa sechipembenene, yakadai seBarium chloride, kudzora zvipembenene zvakasiyana-siyana zvirimwa. Inogona zvakare kushandiswa pakunatsa brine nemvura yemubhoti yeElectrolytic caustic kugadzirwa. Zvakare inoshandiswa pakugadzirira pigment. Maindasitiri ezviuru uye maindasitiri anoishandisa serineti uye mumiririri wekutakura weshungu.
2.. Kusavimbika uye isina kuchena chena poda, chinhu chinogona kupa musiyano wakanaka mumuviri panguva yeX-ray bvunzo. Medium Barium Sulfate haina kunyudzwa mugwara regastrointestinal uye haikonzere allergic maitiro. Iyo haina solull barium compound yakadai seBarium chloride, Barium Sulfide, uye Barium Carbonate. Inonyanya kushandiswa kune gastrointestinal fungidziro, dzimwe nguva inoshandiswa kune zvimwe zvinangwa zvekuongororwa

7, nzira yekugadzirira
Kugadzirwa kwemaindasitiri kweMetallic Bariumyakakamurwa kuita nhanho mbiri: kugadzirwa kweiyo atium oxide uye simbi yekudzora kuderedzwa (aluminium thermal kuderedzwa). Na1000-1200 ℃,Metallic Bariuminogona kuwanikwa nekuderedza luium xide ne simbi aluminium, uye yakazonatswa necuum distillation. Aluminium thermal kuderedza nzira yekugadzira metallic barium: nekuda kwezvinhu zvakasiyana zvinongedzo, panogona kunge paine maviri maitiro eAluminium kuderedza oxide. Iyo yekugadzirisa equation ndeye: Ese maitiro anogona chete kuburitsa chidiki chidiki cheBarium na 1000-1200 ℃. Naizvozvo, pombi yevacuum inofanira kushandiswa kuenderera mberi nekuenderera mberi kweBarium Vapor kubva kune reaction nzvimbo kune inotonhora nzvimbo yekudzandisa kuitira kuti uenderere mberi kuenda kurudyi. Iyo yakasara mushure mekuita kwacho kucheka uye kunoda kubatwa usati warasa
