MOLYBDENUM (Mo) - (Molybdenum) metal of gray-steel color in a compact condition and black-steel in dispersed.
Density of molybdenum is 10,2 g/sm3, fusing temperature of molybdenum - 2620 °С, boiling temperature of molybdenum - 4630 °С.
Scopes. Molybdenum is applied as an alloying additive to various alloys, both to high-quality steels. Molybdenum and molybdenum alloys are used: in details, long working in vacuum to 1800 °С(in nozzles of rockets and in electrovacuum devices), as a constructional material in power nuclear reactors, for manufacturing of the equipment working in excited environments, as a microadditive in fertilizers, Molybdenum disulfide (MoS2) as lubricant.
