Vanadium Vanadium:
Metallic chemical element symbol V and atomic number 23, and is one of the transition elements of the periodic table. Vanadium was discovered in 1801 in Mexico by Andres Manuel del Rio, but the confusion between him and chrome, and was re-discovered in 1830 by Swedish chemist Niels Jibril Sevastrem. Metallic chemical element symbol V and atomic number 23, and is one of the transition elements of the periodic table. Vanadium was discovered in 1801 in Mexico by Andres Manuel del Rio, but the confusion between him and chrome.
Alvanayom is considered one of the very solid elements, the degree of melting 1890 degrees Celsius and a boiling point of 3380 degrees Celsius and its density is 5.96, and the atomic weight of 50.941. And vanadium soluble in nitric acid and sulfuric acid is not soluble in hydrochloric acid and diluted sodium hydroxide and diluted alcohol. And vanadium have several Oksgenih acids, and the third most important vanadium oxide V2O3 and V2O5 vanadium pentoxide. And important for vanadium sulfide VS vanadium and vanadium tri-sulfide compounds VS3 and a bilateral hydroxide vanadium V (OH) 2 and dichloride VCl2 vanadium and vanadium trichloride VCl3 and acid Almitavandhat HVO3.
Vanadium occupies the tenth ranked ninth in terms of the proportion of its presence in the earth's crust, and is not found in the free state, but there is absolutely united with other elements in minerals scattered in all corners of the Earth. It occurs frequently in the United States, Russia and South Africa.
And because of the hardness of vanadium he enters in many alloying alloy such as nickel-vanadium and vanadium - chrome. Vanadium also replaced the platinum in the sulfuric acid industry, and is used widely as an aspect of photographs and as a reductive and dried as in many of the dyes.

Benefits of vanadium and food sources in English: Vanadium • contributes vanadium in the metabolism of bones and teeth may be for that item Dorvi health for humans - (Also found in animal testing). Did not know any emitter disease for lack of this mineral in humans and does not have a Aomahmousy the dose (RDA), and therefore do not need to take any supplements it. • Over the past few years began to interest element vanadium, to the possibility of improving the course of diabetes. We have a lot of research on experimental animals and some limited research conducted on human beings, to study this relationship, • with the emergence of promising results in a Hzhaldddrasat given insulin and vanadium, and found a kind of renewed beta cells in the pancreas and improve the symptoms of diabetes in the first pattern-dependent insulin in mice, after treatment lasted for a year. Mice that were given insulin only did not show them these benefits. • has proven vanadium ability therapeutic in clinical studies on diabetic patients of type I, and also of the style-II, and this Malouhz review in Complementry Medicine magazine article describes vanadium that is similar to insulin, insulin mimic, where it can replace the insulin in part in its ability to metabolize sugar the blood. But this ability to improve the function of insulin and thus reduce the level of blood sugar requires a lot of Alhdhir..kd dose of vanadium be toxic to the body .bl may Tkdh some sort of resistance to the effect of insulin when youve give vanadium. • Food sources: found in vegetables and fresh fruit and seafood such as fish and shellfish.
There is little presence an independent metals in Egypt
USES:
Is used in alloy Elvirovanadiom Ferrovanadium industry, which is at the core cutting machinery industry, engineering steel, power, alloy with gold dental and add copper, bronze and aluminum alloys for aircraft work, glass and ceramic industry drying inks, paints etc.
This is linked deduced extract titanium because it mixed the latter.
