Barium hauv Bolognite

tus txhawv, Elember 56 ntawm lub rooj ntu sij hawm.

Barium hydroxide, Barium chloride, barium sulfate ... yog cov tshuaj tiv thaiv ntau hauv phau ntawv theem siab. Nyob rau hauv 1602, Western alchemists nrhiav tau lub pob zeb bologna (kuj hu ua "Sunstone") uas tuaj yeem tawm teeb. Qhov no hom ore muaj cov muaju me me, uas yuav muaj emit txuas ntxiv mus tom qab raug tshav ntuj. Cov yam ntxwv zoo no fascinated wizards thiab alchemists. Nyob rau hauv 1612, tus paub tseeb Julio Cesare Lagara luam tawm lub laj thawj ntawm Bologence ", uas sau cov ntsiab lus ntawm Bologne", uas sau cov pob zeb ntawm Bologna ", uas tau sau cia los ntawm nws lub ntsiab tivthaiv los ntawm nws lub ntsiab tivthaiv, barite (baso4). Txawm li cas los xij, nyob rau xyoo 2012, cov ntaub ntawv qhia tawm tias Bologna Pob zeb lub lumina tau los ntawm barium sulfide doped nrog monovalent thiab tus tooj liab thiab tooj liab thiab tooj liab ions. Xyoo 1774, Swedish Chemist Sceren pom Barium oxide thiab xa mus rau nws li "baryta" (hnyav lub ntiaj teb), tab sis cov hlau barium yeej tsis tau. Nws tsis tau txog 1808 tias British Chemist David tau txais cov hlau tsis huv los ntawm cov chaw barite los ntawm electrolysis, uas yog barium. Nws tau tom qab muaj npe tom qab cov lus Greek lo lus barys (hnyav) thiab lub cim theem pib ba. Lub npe Suav "BA" los ntawm cov phau ntawv txhais lus Kangxi los ntawm Kangxi phau ntawv txhais lus, txhais tau hais tias tooj liab hlau hlau oree.

Barium hlauyog heev nquag thiab yooj yim reacts nrog huab cua thiab dej. Nws tuaj yeem siv los tshem tawm cov roj av hauv lub tshuab nqus tsev thiab cov duab hlab, nrog rau kom ua alloys, foob pob hluav taws thiab nuclear thiab nuclear reactors. Xyoo 1938, cov kws tshawb fawb pom tau Barium thaum lawv kawm cov khoom tom qab iTancium, thiab xav tias Barium yuav tsum yog ib qho ntawm cov khoom siv uranium nuclear fission. Txawm hais tias muaj ntau kev tshawb pom txog nws yog xim hlau barium, tib neeg tseem siv barium sib txuas ntau zaus.

Qhov ntxov tshaj plaws compound siv yog barite - barium sulfate. Peb tuaj yeem pom nws nyob rau hauv ntau cov ntaub ntawv sib txawv, xws li cov xim dawb hauv cov duab thaij, thiab cov khoom noj khoom haus, kev noj tshuaj kho mob yog lub sijhawm "Barium noj mov" peb noj thaum lub plab zom mov. Barium noj mov "- cov hmoov dawb uas tsis muaj ntxhiab thiab tsis muaj roj thiab roj, thiab nws yuav tsis muaj kev cuam tshuam los ntawm cov kua qaub thiab lwm yam kua hauv lub cev. Vim tias cov kab maticikas loj ntawm barium, nws tuaj yeem tsim cov txiaj ntsig duab hluav taws xob, hluav taws xob xoo hluav taws xob, thiab tsim cov kab yeeb yaj kiab tom qab dhau los ntawm tib neeg cov nqaij. Nws tuaj yeem siv los txhim kho qhov sib piv ntawm cov zaub, yog li ntawd cov organs lossis cov nqaij tus neeg sawv cev sib txawv ntawm zaj duab xis, yog li ua kom tiav cov kev hloov pauv sib txawv, thiab cov kev hloov pauv ntawm cov kev hloov pauv ntawm tib neeg. Barium tsis yog qhov tseem ceeb rau tib neeg, thiab insoluble barium sulfate yog siv nyob rau hauv barium noj mov, yog li nws yuav tsis muaj kev cuam tshuam loj rau tib neeg lub cev.

Tab sis lwm qhov sib txawv bar Tsuas yog los ntawm nws lub npe, ib tus tuaj yeem qhia nws cov kev phom sij. Tus yuam sij sib txawv ntawm nws thiab barium sulfate yog tias nws yog soluble hauv dej thiab acid, ua ntau barble ions, ua rau hypokalemia. Mob caj dab roj ntsev yog tsis tshua muaj, feem ntau tshwm sim los ntawm kev noj ntsev kom tsis zoo. Cov tsos mob zoo ib yam li mob plab, yog li nws tau pom zoo kom mus rau hauv tsev kho mob kom noj sodium tee lossis sodium thiosulfate rau detoxification. Qee cov nroj tsuag muaj cov haujlwm ntawm kev nqus thiab sau barium, xws li algae ntsuab, uas xav tau barium kom loj hlob zoo; Brazil txiv ntseej tseem muaj 1% barium, yog li nws yog ib qho tseem ceeb kom haus lawv hauv kev sim. Txawm yog li, featerite tseem ua lub luag haujlwm tseem ceeb hauv kev tsim cov tshuaj. Nws yog ib feem ntawm ci. Thaum ua ke nrog lwm cov oxides, nws kuj tuaj yeem qhia cov xim tshwj xeeb, uas yog siv los ua cov khoom siv sib xyaw ua ke thiab iav kho qhov muag.

Cov tshuaj lom neeg endothermic kev tawm tsam yog feem ntau ua nrog barium hydroxide: Tom qab tov cov tshuaj lom neeg ammonium, muaj cov tshuaj tiv thaiv ammonium, tuaj yeem tshwm sim. Yog tias ob peb tee dej ntws tau poob rau hauv qab ntawm lub khob, dej khov tsim los ntawm cov dej tuaj yeem pom, thiab txawm tias cov iav ua kom khov thiab daig rau hauv qab ntawm lub khob. Barium hydroxide muaj qhov muaj zog alkalinity thiab yog siv los ua cov catalyst rau synloum resins. Nws tuaj yeem sib cais thiab precipitate sulfate ions thiab tsim cov khoom siv barium. Nyob rau hauv cov nqe lus ntawm kev tsom xam cov pa roj carbon dioxide cov ntsiab lus nyob rau hauv huab cua thiab qhov ntsuas kom ntsuas cov tshuaj ntawm chlorophyll xav tau kev siv ntawm barium hydroxide. Hauv kev tsim cov ntsev, tib neeg tau tsim kho kom zoo nkauj heev: Dej nyab hauv Florence xyoo 1966 tau ua tiav los ntawm kev rov ua dua tshiab ntawm Gypsum (calcium sulfate) los tsim barium sulfate.

Lwm yam kev sib txuas lus muaj cov khoom sib txuas tseem muaj kev nthuav tawm cov yam ntxwv zoo nkauj, xws li cov Photorefhaon thaj chaw ntawm Barium Titanate; Lub siab-kub superconductivity ntawm YBA2CU3O7, nrog rau cov xim ntsuab ntawm cov xim av hauv cov lag luam hluav taws hauv cov pob hluav taws, muaj txhua tus ua cov khoom tseem ceeb ntawm barium.
