Daim ntawv thov

Barium yog cov tshuaj lom neeg lub cim nrog cim BA thiab atomic tus lej 56. Nws yog cov khoom noj thib tsib hauv pab pawg 2, muag muag muag ntawm cov hlau alkaline. Vim tias nws cov tshuaj lom neeg zoo li cas, barium yeej tsis pom nyob rau hauv cov uas yog lub caij dawb.

Cov Ntawv Thov: Hlau thiab alloys, cov kabmob alloys; coj-tin soldering alloys - kom nce cov creep resistance; Alloy nrog Nickel rau Spark Plugs; Additive rau cov hlau thiab nrum hlau ua ib qho inoculant; Alloys nrog calcium, manganese, silicon, thiab txhuas raws li high-qib steel deoxidizers.Barium tsuas muaj ob peb daim ntawv thov kev lag luam. Cov hlau tau ua keeb kwm siv los ua scavenge huab cua hauv lub tshuab nqus tsev. Nws yog ib qho ntawm

Barium, raws li ib hlau los yog thaum sib cais nrog cov roj txhuas, yog siv los tshem tawm cov roj av uas tsis muaj txiaj ntsig (guttering) los ntawm lub tshuab nqus tsev, xws li TV daim duab hlab. Barium yog haum rau lub hom phiaj no vim tias nws cov vapor qis thiab cuam tshuam rau oxygen, nitrogen, carbon dioxide, thiab dej; Nws muaj peev xwm txawm tias tshem cov roj uas zoo heev los ntawm kev ua rau lawv ua rau lawv nyob hauv lub crystal lattice.
