Cov ntaub ntawv tseem ceeb ntawm molybdenum

Molybdenum, chemical cim Mo, yog cov khoom siv tshuaj lom neeg nrog atomic tooj 42 thiab yog cov hlau hloov pauv. Nws qhov hnyav yog 95.96 g / mol. Nws muaj lub siab melting point, corrosion kuj thiab zoo mechanical zog.

Molybdenum yog cov hlau tsis muaj zog, tsis yooj yim corroded los ntawm cov kua qaub thiab cov hauv paus, tab sis tuaj yeem tsim cov tebchaw nrog ntau lub ntsiab lus, thiab nws lub xeev oxidation feem ntau yog +4, +5, lossis +6. Molybdenum yog dav siv hauv metallurgy, electronics, tshuaj lom neeg kev lag luam, thiab cov ntaub ntawv science. Hauv kev lag luam metallurgical, molybdenum yog siv rau hauv kev tsim cov khoom siv kub, refractory alloys thiab high-speed steel; nyob rau hauv kev lag luam hluav taws xob, molybdenum plays lub luag haujlwm tseem ceeb hauv semiconductors, vaj huam sib luag tiaj tus thiab hnub ci vaj huam sib luag; hauv kev lag luam tshuaj, molybdenum yog siv rau hauv catalysts, coatings thiab pigments; Hauv cov ntaub ntawv tshawb fawb, molybdenum alloys tau siv dav hauv aerospace, automotive manufacturing thiab cov khoom siv kho mob.

Tsis tas li ntawd, molybdenum plays lub luag haujlwm tseem ceeb hauv tib neeg cov metabolism hauv cov kab mob. Nws yog feem ntau koom nrog hauv kev tsim cov coenzymes hauv daim ntawv ntawm molybdenum enzymes, uas ua kom muaj ntau yam oxidoreductases thiab ua lub luag haujlwm tseem ceeb hauv nitrogen metabolism thiab lwm yam kev cuam tshuam biochemical tseem ceeb.
