Oxygen-dawb tooj liab
Cov tooj liab ntshiab tsis muaj cov pa oxygen lossis cov deoxidizer residue. Tab sis qhov tseeb, nws tseem muaj cov kab ntau ntawm cov pa oxygen thiab qee qhov impurities. Raws li tus qauv, cov ntsiab lus oxygen tsis ntau tshaj {{0}}.003%, tag nrho cov ntsiab lus impurity tsis ntau tshaj 0.05%, thiab purity ntawm tooj liab ntau dua 99.95%.
Oxygen-dawb tooj liab cov khoom siv tsuas yog siv hauv kev lag luam hluav taws xob. Lawv feem ntau ua rau cov hlau tsis muaj oxygen, cov hlau tsis muaj oxygen, cov hlau tsis muaj oxygen thiab lwm yam khoom siv tooj liab.
