Results 1–3 of 3 for molibden
molybdenum → molibden
Molybdenum was discovered by Carl William Scheele (Sweden) in 1778. The origin of the name comes from the Greek word molybdos meaning lead. It is silvery white, very hard metal, but is softer and more ductile than tungsten. Molybdenum is found in the minerals molybdenite (MoS2) and wulfenite (MoO4Pb). Its alloys are used in aircraft, missiles and protective coatings in boiler plate.
refractory metal → vatrostalni metal
Refractory metal is a metal having an extremely high melting point, for example tungsten, molybdenum, niobium, tantalum, and rhenium
rhenium → renij
Rhenium was discovered by Walter Noddack, Ida Tacke and Otto Berg (Germany) in 1925. The origin of the name comes from the Latin word Rhenus meaning river Rhine. It is rare and costly, dense, silvery-white metal. Tarnishes in moist air. Resists corrosion and oxidation. Dissolves in nitric and sulfuric acids. Has a very high melting point. Rhenium is found in small amounts in gadolinite and molybdenite. Mixed with tungsten or platinum to make filaments for mass spectrographs. Its main value is as a trace alloying agent for hardening metal components that are subjected to continuous frictional forces.
