(1) Kukonzekera kwa Barum Oxide
ORD-Cardite Ore Ayenera kukhala osankhidwa ndikusankhidwa ndi manja, kenako silika ndi silika amachotsedwa kuti apeze zambiri zopitilira 96% ya barium sulfate. Ufa wa ore wokhala ndi kukula kwa mesh osakanizidwa ndi malasha kapena mafuta a petroleum coke ufa muyezo wolemera wa 4: 1, ndikuwotcha pa 1100 ℃ mu ng'anjo yobwereka. Barfate Sulfate imachepetsedwa ku barium sulfide (yomwe imadziwika kuti "phulusa lakuda"), ndipo adapeza bango sulfide adalumikizidwa ndi madzi otentha. Pofuna kutembenuza barium sulfide mpweya wabwino, sodium carbonate kapena kaboni dayokisiyi ayenera kuwonjezeredwa ku barium sulfide yankho. Barwary oxide amatha kuphatikizidwa ndikusakaniza barium carbonate yokhala ndi kaboni ndikuziwerengera pa 800 ℃. Tiyenera kudziwa kuti barium oxide imayamwa ma baum kuti apange barium peroxide pa 500-700 ℃, ndipo a Barium peroxide amatha kuwola kuti apange barium On 700-800 ℃. Chifukwa chake, kuti tipewe kupanga barium peroxide, chinthu chowerengera chimayenera kukhazikika kapena kufikika pansi pa chitetezo cha bat.
(2) Njira yochepetsera yochepetsera ya aluminothermic kuti ipange barium melallic
Chifukwa cha zosakaniza zosiyanasiyana, pali zochitika ziwiri za aluminiyamu kuchepetsa barium oxide:
6Ago + 2al → 3mbao • Al2o3 + 3B ↑
Kapena: 4bao + 2al → Bao • Alyo3 + 3B ↑
Pa 1000-1200 ℃, zochitika ziwiri izi zimatulutsa barium pang'ono, motero pampu ya vamium imafunikira kusamutsa ma bapoti a barium kuchokera kudera logwirizana kuti zitheke kuti zitheke. Zotsalira pambuyo pazochitikazo zikakhala poxic ndipo zikuyenera kuthandizidwa isanatayikidwe.
Kukonzekera kwa marrium wamba
(1) Njira yokonzekera barium carbonate
Njira ya Carbotion
Njira yogwirizira ntchito imaphatikizapo kusakaniza Arite ndi malasha m'malo ena, kuwapukuta ku ratary ndikuwachepetsa. Carbon Dioxide imayambitsidwa mu barium sulfizide njira ya mpweya, ndipo zomwe zikuchitikazo:
Bas + CO2 + H2o = Baco3 + h2s
Kulandila barium carbonate kumasungunuka, kutsukidwa ndi kutsuka ndikusefa pang'ono, kenako ndikuwuma ndikuphwanya 300 ℃ kupeza mankhwala omaliza a barbonate. Njirayi ndiyosavuta mu njira komanso yotsika mtengo, motero amatengedwa ndi opanga ambiri.
② Njira yopumira kawiri
Barmium sulfide ndi ammonium carbonate kawiri kawirikawiri, ndipo zomwe zikuchitikazo:
BUD + (NH4) 2CE3 = Baco3 + (nh4) 2s
Kapena barium chloride zomwe zimakhudzidwa ndi potaziyamu Carbonate, ndipo zomwe zikuchitikazo zili motere:
Bacl2 + K2Co3 = Baco3 + 2kCL
Zoyikidwazo zomwe zimapezekazo zikutsukidwa, zosefedwa, zowuma, etc. kuti mupeze mankhwala omaliza a barbonate.
Njira ya barium carbonate njira
Barbium Carbonate ufa wachitika ndi mchere wamchere kuti upange mchere wa barium, ndipo ammonium carbonate amabwezeretsanso. Mchere wa barbium sungunura umawonjezeredwa ku Ammonium carbonate yopanga mankhwala ogulitsa a Carbonate, omwe amasefedwa ndikuwuma kuti apange chinthu chomaliza. Kuphatikiza apo, mbalamezo zakumwa zimapezeka zitha kubwezeretsedwanso. Zomwe zikuchitikazo:
COCO3 + 2HCL = Bacl2 + H2O + CO2
Bacl2 + 2nh4oh = Ba (oh) 2 + 2nh4cl
Ba (oh) 2 + CO2 = Bao3 + h2o
(2) Njira yokonzekera Baria Titanate
① Njira yolimba yolimba
Baruma Titachate amatha kupezeka pokambirana barium carbonate ndi Titanium dioxide, ndipo zida zina zilizonse zitha kuzimitsidwa. Zomwe zikuchitikazo:
TiO2 + COCO3 = CATIO3 + CO2.
Njira ya Coprecitation
Barium chloride ndi titanium tetrachloride amasakanikirana ndikusungunuka chimodzimodzi, kuphatikiza kwa 70 ° C, kenako ndikutsuka, kutsuka, ndipo Kenako Pyrolyzed kuti apeze barium Tinanate. Zomwe zikuchitikazo:
Bacl2 + ticl4 + 2h2c2o4 + 5h2o = batio (c2o4) 2 • 4h2o ↓ + 6h2o
CATIO (C2O4) 2 • 4h2o = CATIO3 + 2co2 ↑ + 2Co ↑ + 4H2O
Atagundira metitanic acid, barcium chloride njira imawonjezeredwa, kenako ammonium carbonate amawonjezeredwa pansi pa cruium carbonate ndi metatithanic acid. Zomwe zikuchitikazo:
Bacl2 + (NH4) 2CO3 = Baco3 + 2nh4CL
H2TIO3 + = CATIO3 + CO2 ↑ OR + H2O
(3) Kukonzekera kwa barium chloride
Kupanga kwa bareum chloride makamaka kumaphatikizapo njira ya hydrochloric acid, barborium carbonate njira, njira yosinthira kapena zopangira.
① hydrochloric acid njira. Pamene barium sulfide imathandizidwa ndi hydrochloric acid, zomwe zimachitika:
Bas + 2hci = Bacl2 + h2s ↑ q
Njira ya ②barium carbonate njira. Opangidwa ndi barium carbonate (barium carbonate) ngati raw zinthu, zotsatira zazikulu ndi:
COCO3 + 2HCI = Bacl2 + CO2 ↑ OR + H2O
Njira ya ③carbotion
Zotsatira za Barium pa Thanzi laumunthu
Kodi Barium imakhudza bwanji thanzi?
Barium si chinthu chofunikira kwa thupi la munthu, koma chimakhudza kwambiri thanzi laumunthu. Barium akhoza kuwonetsedwa ndi barium mu mabiramu migodi, kununkhira, kupanga, komanso kugwiritsa ntchito ma barium. Barium ndi mankhwala ake amatha kulowa thupi kudzera mu thirakiti la kupuma, m'mimba thirakiti, ndi khungu lowonongeka. Poizoni wa Barium amayamba chifukwa cha kupuma kupuma, komwe kumachitika pa ngozi pakupanga ndi kugwiritsa ntchito; Poizoni wosagwiritsidwa ntchito wopanda ntchito amayamba chifukwa cholowetsedwa m'mimba, makamaka chifukwa cha kulowa mwangozi; Mankhwala osungunuka amadzimadzi amatha kutengedwa pakhungu lovulala. Poizoni wa barium amachitika chifukwa cha kulowa mwangozi.
Kugwiritsa Ntchito Zachipatala
(1) Baraum kudya radiography
Barrium Chakudya cha Radiography, omwe amadziwikanso kuti m'mimba thirakisi radium radiography, ndi njira yoyeserera yomwe imagwiritsa ntchito wothandizila kuwonetsa ngati pali zotupa mu x-raradiation. Barrium Walkragraphy ndi kulowetsa kwa ma barfate omwe amagwiritsidwa ntchito ngati wothandizila m'madzi ndi lipids ndipo sadzatengeka ndi anthu osankha.
Malinga ndi zosowa za matenda azachipatala ndi chithandizo, mankhwala am'mimba am'mimba amathanso kudya kwambiri balola, bastroincastinal chakudya chambiri, corron barmium ma bacium amayesedwa.
Barium poizoni
Njira Zowonekera
Barium ikhoza kuwonetsedwamphalaPa mabiramu migodi, onunkhira, ndi kupanga. Kuphatikiza apo, Barium ndi mankhwala ake amagwiritsidwa ntchito kwambiri. Barciary wamba Mchere umaphatikizapo barium carbonate, bauum chloride, barium sulfide, barium nitrate, ndi barium oxide. Zina zamasiku onse zimakhala ndi mabiliyoni, monga barium suldude mu mankhwala ochotsa tsitsi. Ma othandizira ena azaulimi kapena oyendetsa ndege amakhalanso ndi ma barts souliralika monga barium chloride ndi barbowate.
