1. Introduction. Although molybdenum represents a vanishingly small portion of the earth's crust, it is the most prevalent transition metal in seawater [1, 2] owing to the high water solubility of molybdate.Given the high bioavailability of molybdenum, it is hardly surprising that living organisms have taken advantage of the chemical versatility of molybdenum …
Abstract. In situ x‐ray diffraction (XRD) technique was employed to study unstable phases formed in sintered or anodically oxidized tungsten and molybdenum xide film electrodes under electrocoloration conditions in, in order to discuss their electrochromic characteristics on the basis of structural properties.
Powder metallurgy products made from molybdenum alloys with a rhenium content above 40 weight percent are traditionally used for many high temperature applications. The resistance to thermal shock and high temperature strength of the molybdenum-rhenium alloys make them often the best choice for applications such as: heat sinks, heating …
