The BP oil-methane-dispersant-drilling fluids disaster 2010-08-12T16:45:00Z Unlike in most batteries, where one chemical turns into another chemical as it releases or stores charge, the vanadium in this type of battery simply takes on or releases electrons. Batteries That Go With The Flow 2010-07-19T10:00:00Z Important mines of gold and silver, considerable deposits of wolframite, valuable ores of molybdenum and vanadium, and quarries of onyx marble, are also worked. Encyclopaedia Britannica, 11th Edition, Volume 2, Slice 5 "Arculf" to "Armour, Philip" Chromium and vanadium have a 'stabilizing' effect, i.e. tend to make large masses of the alloy homogeneous, and to make the alloy retain its hardness over wide ranges of temperature. The New Gresham Encyclopedia. Vol. 1 Part 1 A to Amide And because vanadium steel retains its hardness at high temperatures, it is used in drill bits, circular saws, engine turbines and other moving parts that generate a lot of heat. The metal that can store power for a small town 2014-06-13T04:00:00Z The other metals reported in the official returns are lead, cobalt and vanadium, of which only small quantities are produced. Encyclopaedia Britannica, 11th Edition, Volume 6, Slice 2 "Chicago, University of" to "Chiton" Chemically related to vanadium are the two elements tantalum and columbium or niobium. Encyclopaedia Britannica, 11th Edition, Volume 6, Slice 1 "Châtelet" to "Chicago" A variety known as cuprodescloizite is dull green in colour; it contains a considerable amount of copper replacing zinc and some arsenic replacing vanadium. Encyclopaedia Britannica, 11th Edition, Volume 8, Slice 2 "Demijohn" to "Destructor" Molybdenum, vanadium, manganese, and all the substitutes were commandeered to take its place; but month by month the price of tungsten crept up until now all the West was tungsten-mad. Shadow Mountain Each change of colour represents one further electron being passed on to the vanadium. The metal that can store power for a small town 2014-06-13T04:00:00Z And yet vanadium is, as Dr. Hayes has shown, a very widely diffused metal. The Galaxy Vol. 23, No. 1 Its supplies of the following are inadequate: antimony, asbestos, kaolin, chromate, corundum, garnet, manganese, emery, nitrates, potash, pumice, tungsten, vanadium, zirconium.

The Mines and its Wonders Ever find any vanadium or manganese around here? Shadow Mountain Two-thirds of the world's supply of vanadium comes from Peru, where the mines are under American control. The Economic Aspect of Geology It is a beautiful green precipitate, but at present simply a curiosity, owing to the rarity of the metal vanadium. Field's Chromatography or Treatise on Colours and Pigments as Used by Artists They also use a quantity of vanadium steel imported from America and furnished by the American Vanadium Company. A Journey Through France in War Time If vanadium contained is considerable it also combines with the carbon, forming carbides. The Working of Steel Annealing, Heat Treating and Hardening of Carbon and Alloy Steel This has an advantage in case carbon-free metals are desired and the process is used for producing manganese, tungsten, titanium, molybdenum, vanadium and their allows with iron and copper. Creative Chemistry Descriptive of Recent Achievements in the Chemical Industries There are some fairly large deposits of vanadium minerals in Asiatic Russia, which may ultimately become an important source. The Economic Aspect of Geology It will be seen that scandium and yttrium, of the positive group, differ only in details from vanadium and niobium, of the negative group; the ground-plan on which they are built is the same. Occult Chemistry Clairvoyant Observations on the Chemical Elements Other airmen of yours have just reported that nothing can be found but ruins of the Socialist refuge, there—nothing but those, and the half-melted vanadium steel identification-tags of your best scouts! The Air Trust It would seem that vanadium has the effect of intensifying the action of chromium and manganese, or that vanadium is intensified by the action of chromium or manganese. The Working of Steel Annealing, Heat Treating and Hardening of Carbon and Alloy Steel Yet if it had not been for vanadium steel we should have no Ford cars. Creative Chemistry Descriptive of Recent Achievements in the Chemical Industries The United States supplies less than one-half of its normal needs of vanadium, from southwestern Colorado and southeastern Utah. The Economic Aspect of Geology Its negative complement consists of nitrogen, vanadium and niobium, and we have again to note that nitrogen, like hydrogen and oxygen, departs from its group type. Occult Chemistry Clairvoyant Observations on the Chemical Elements The authorities delight in telling the neutral visitors that they have found adequate substitutes for nickel, chromium, and vanadium for the hardening of steel. The Land of Deepening Shadow Germany-at-War The full effect of vanadium is not felt unless the temperatures to which the steel is heated for hardening are raised considerably. The Working of Steel Annealing, Heat Treating and Hardening of Carbon and Alloy Steel These bridge pieces were formed from chrome vanadium steel and milled to an 'H' section, and the bearings for the valve-tappet were forged solid with them. A History of Aeronautics Through its commercial control of the Peruvian deposits, the United States dominates the world's vanadium situation. The Economic Aspect of Geology The A funnel of vanadium repeats the A funnel of scandium, with the addition of d 20, already studied. Occult Chemistry Clairvoyant Observations on the Chemical Elements For working on high carbon steel, a rod of the steel being welded must be employed and for alloy steels, such as nickel, manganese, vanadium, etc., special rods of suitable alloy composition are preferable. Oxy-Acetylene Welding and Cutting Electric, Forge and Thermit Welding together with related methods and materials used in metal working and the oxygen process for removal of carbon Where price is the leading factor, there are many cases where a stronger steel can be obtained from the chrome and vanadium than the nickel-chrome. The Working of Steel Annealing, Heat Treating and Hardening of Carbon and Alloy Steel With it we can get the greatest strength with the least weight, but it would not be good business to let our whole future depend upon being able to get vanadium steel. My Life and Work The patronite has altered at the surface to red and brown hydrated vanadium oxides. The Economic Aspect of Geology The corresponding group consists of nitrogen, vanadium and niobium; they are triatomic, paramagnetic, and negative. Occult Chemistry Clairvoyant Observations on the Chemical Elements Nickel steel rods may be used for parts requiring great strength, but vanadium alloys are very difficult to handle. Oxy-Acetylene Welding and Cutting Electric, Forge and Thermit Welding together with related methods and materials used in metal working and the oxygen process for removal of carbon It soon became evident that vanadium used in larger quantities than necessary as a scavenger imparted to the steel a much greater cutting efficiency. The Working of Steel Annealing, Heat Treating and Hardening of Carbon and Alloy Steel Of course they are not all the same kind of vanadium steel. My Life and Work There are other deposits containing small amounts of vanadium which are not at present available as ores. The Economic Aspect of Geology In this way does vanadium succeed in overtopping scandium by 126 atoms. Occult Chemistry Clairvoyant Observations on the Chemical Elements The vanadium steel quadrangle being in place, the next task was to adjust the wide stretching wing-frames of the big plane. The Boy Aviators' Treasure Quest The following table shows the percentages of carbon, manganese, nickel, chromium and vanadium in typical steel alloys for engineering purposes. The Working of Steel Annealing, Heat Treating and Hardening of Carbon and Alloy Steel The vanadium steel disposed of much of the weight. My Life and Work Titaniferous iron ores, extensive deposits of which are known in many places, usually contain a small percentage of vanadium. The Economic Aspect of Geology The plant was a row of long low buildings of brick on the outskirts of the city, once devoted to the making of vanadium steel. The War Terror In many places I saw mounds the marmots had made from copper ore and farther north some from minerals containing wolfram and vanadium. Beasts, Men and Gods A representative steel contains approximately 24 per cent of alloying metals, namely, tungsten, chromium, vanadium, silicon, manganese, and in addition there is often found cobalt, molybdenum, uranium, nickel, tin, copper and arsenic. The Working of Steel Annealing, Heat Treating and Hardening of Carbon and Alloy Steel He found eventually that it was a French steel and that there was vanadium in it. My Life and Work Outside of the Peruvian deposit, the affiliations of which are doubtful, the vanadium deposits of economic importance owe their positions and values mainly to the action of surface processes, rather than to igneous activity. The Economic Aspect of Geology It's a peculiar mixture of aluminum and vanadium steel. Tom Swift and His Air Scout, or, Uncle Sam's Mastery of the Sky The low-grade ores of the United States range from 1 to 8 per cent of vanadium oxide, the general mean being nearer the lower figure. The Economic Aspect of Geology Page 25 Nickel influences the strength and ductility of steel by being dissolved directly in the iron or ferrite; in this respect differing from chromium, tungsten and vanadium. The Working of Steel Annealing, Heat Treating and Hardening of Carbon and Alloy Steel We tried every steel maker in America—not one could make vanadium steel. My Life and Work Some of the ore runs as high as 4 per cent uranium oxide, and the ore carries appreciable amounts of copper but very little vanadium. The Economic Aspect of Geology The Germans during the war supplied their needs for vanadium from the minette iron ores in the Briey district in France, and presumably the French will in the future utilize this source. The Economic Aspect of Geology The deposits contain small amounts of fossil wood which may have been an agent in the precipitation of the vanadium. The Economic Aspect of Geology Where tools have to withstand shocks and vibration, as in pneumatic hammer work, in severe punching duty, hot or cold upsetting or similar work, tool steels containing vanadium or chrome-vanadium give excellent results.
