Definition of molybdenum in English: molybdenumnoun məˈlɪbdənəmməˈlɪbdənəm mass nounThe chemical element of atomic number 42, a brittle silver-grey metal of the transition series, used in some alloy steels. (化学元素)钼(符号: Mo ) Example sentencesExamples - Common hydroprocessing catalysts consist of an aluminum oxide carrier on to which the metals molybdenum and nickel or cobalt are added.
- The corresponding loss in yield strength is compensated by alloying with vanadium, nitrogen, chromium, molybdenum, and titanium.
- Vanadium, molybdenum, niobium, titanium, chromium, nickel, manganese are but a few of the many metals which make their way into steel to yield alloys with special properties.
- One might be able to recover from waste relatively pure metals, such as chromium and molybdenum, which are for all practical purposes identical to unused materials.
- We added copper, cobalt, selenium, molybdenum, etc to the deficient soils and transformed the plant and animal health.
OriginEarly 19th century: modern Latin, earlier molybdena (originally denoting a salt of lead), from Greek molubdaina 'plummet', from molubdos 'lead'.
