Dab tsi yog barium hlau nonmetal lossis metalloid?

Barium hlauyog ib qho reactive heev uas belongs rau alkaline ntiaj teb hlau pawg ntawm lub periodic rooj. Nws yog silvery-dawb hlau paub txog nws cov reactivity siab thiab muaj peev xwm los npaj cov tebchaw. Tab sis yog barium hlau tsis yog hlau lossis metalloid?

Cov lus teb yog qhov tseeb - barium yog hlau. Raws li ib feem ntawm alkaline ntiaj teb hlau pawg, nws muaj cov khoom siv hlau xws li hluav taws xob thiab thermal conductivity, ductility thiab ductility. Bariumis kuj yog cov hlau hnyav nrog tus lej atomic siab, ua rau nws ua piv txwv classic ntawm cov hlau.

Ib qho ntawm cov khoom tseem ceeb ntawmbarium hlauyog nws siab purity. Qhov no ua rau nws nrov nyob rau hauv ntau yam kev lag luam kev siv, nrog rau kev tsim cov alloys, pigments thiab foob pob hluav taws. High-purity hlau barium muaj ib tug purity ntawm 99.9% thiab feem ntau yog siv nyob rau hauv lub tsim ntawm lub tshuab nqus tsev raj, fluorescent teeb thiab lwm yam khoom siv hluav taws xob. Nws siab reactivity thiab conductivity yog heev pab tau.

Barium hlau yog 99.9% ntshiab thiab tsis muaj impurities uas yuav cuam tshuam nws cov kev ua tau zoo nyob rau hauv ntau yam kev siv. Qib no ntawm purity ua kom ntseeg tau tias barium hlau nthuav tawm cov khoom tsim nyog, ua rau nws muaj kev ntseeg siab thiab zoo ib yam khoom siv hauv kev lag luam.

Hais txog cov tshuaj muaj pes tsawg leeg, barium hlau muaj CAS tus lej ntawm 7440-39-3, qhia tau hais tias nws yog ib tug tshwj xeeb compound. Lub siab purity ntawm barium hlau thiab nws tus lej CAS tshwj xeeb ua rau nws yooj yim los taug qab thiab txheeb xyuas qhov zoo thiab keeb kwm ntawm cov khoom, ua kom nws ua tau raws li cov qauv nruj uas yuav tsum tau siv rau kev lag luam.

Hauv kev xaus, barium hlau yog cov hlau thiab nws cov purity siab ntawm 99.9% thiab CAS tooj7440-39-3 : kuvua rau nws muaj txiaj ntsig thiab txhim khu kev qha cov ntaub ntawv hauv ntau daim ntawv thov kev lag luam. Nws cov khoom thiab qib purity ua rau nws yog ib qho tseem ceeb hauv kev tsim khoom ntawm ntau yam khoom uas nws cov reactivity thiab conductivity tseem ceeb heev.
