Lub cev muaj zog ntawm Molybdenum

Molybdenum yog ib qho kev hloov pauv hlau nrog ntau lub cev tseem ceeb. Nws muaj qhov ceev txog li 10.3 g / cm³ thiab melting point txog 2620 ± 10 degree, uas muab nws zoo heev stability thiab corrosion kuj ntawm kub kub. Qhov no silvery-dawb hlau muaj lub cev-centered cubic siv lead ua qauv, uas muab molybdenum nws muaj zog zog.

Molybdenum muaj ib coefficient ntawm expansion (linear expansion) ntawm kwv yees li %. Nws cov coefficient tsawg ntawm kev nthuav dav qhia tau hais tias molybdenum muaj qhov siab ntawm qhov ruaj khov txawm tias qhov kub hloov pauv. Molybdenum yog ib qho zoo heev thermally conductive khoom nrog ib tug thermal conductivity ntawm kwv yees li 138 W / (mK). Qhov no ua rau molybdenum ua kom muaj cua sov zoo hauv qhov kub thiab txias thiab yog li siv dav hauv ntau cov ntawv thov kub. Tsis tas li ntawd, molybdenum yog ib qho hluav taws xob zoo hluav taws xob nrog kev ua haujlwm ntawm kwv yees li 1.87 × 106 S / m. Qhov no ua rau molybdenum pab tau hauv electronics thiab semiconductors. Molybdenum tiv taus huab cua, dej thiab ntau cov kua qaub. Nws muaj peev xwm tsim cov yeeb yaj kiab oxide ntom ntom tiv thaiv kev tiv thaiv corrosion ntxiv los ntawm qhov tshwm sim. Qhov no ua rau molybdenum dav siv hauv kev npaj cov khoom siv corrosion-resistant.
