Enjoying the "chemistry series"? If you have found several of the park and grab caches from this series, don't expect the same hide here. Parking can be found nearby (N41° 10.164, W96° 3.747). Very near a walking path and somewhat close to some houses... so be aware of who may be watching before making the grab.
This is part of a series of caches all using the same container. The experiment continues... first, the container was proven to be waterproof as long as you replace the lid tightly (please do). Second, they seem to be holding up in the elements, at least for the short term. No real complaints about the internal log construction... now it is time to get a bit more creative with the camouflage and find some more challenging places to hide these. Hope you enjoy this one.
************************* VANADIUM *************************
Atomic Number: 23
Symbol: V
Atomic Weight: 50.9415
Discovery: Depending who you ask: del Rio 1801 or Nils Gabriel Sefstrom 1830 (Sweden)
Word Origin: Vanadis, a Scandinavian goddess. Named after the goddess because of vanadium's beautiful multicolored compounds.
Properties: Vanadium has a melting point of 1890+/-10°C, boiling point of 3380°C, specific gravity of 6.11 (18.7°C), with a valence of 2, 3, 4, or 5. Pure vanadium is a soft, ductile bright white metal. Vanadium has good corrosion resistance to alkalis, sulfuric acid, hydrochloric acid, and saltwater, but it oxidizes readily at temperatures exceeding 660°C. The metal has good structural strength and a low fission neutron cross section. Vanadium and all of its compounds are toxic and should be handled with care.
Uses: Vanadium is used in nuclear applications, for producing rust-resistant spring and high-speed tool steels, and as a carbide stabilizer in making steels. Approximately 80% of the vanadium that is produced is used as a steel additive or ferrovanadium. Vanadium foil is used as a bonding agent for cladding steel with titanium. Vanadium pentoxide is used as a catalyst, as a mordant for dyeing and printing fabrics, in the manufacture of aniline black, and in the ceramics industry. Vanadium-gallium tape is used to produce superconducting magnets.
Sources: Vanadium occurs in approximately 65 minerals, including vanadinite, carnotite, patronite, and roscoelite. It is also found in certain iron ores and phosphate rock and in some crude oils as organic complexes. Vanadium is found in small percentages in meteorites. High purity ductile vanadium may be obtained by reducing vanadium trichloride with magnesium or a magnesium-sodium mixture. Vanadium metal also may be produced by calcium reduction of V2O5 in a pressure vessel.
