Production and General information of rhenium
Very rich reserves of rhenium is Chile, USA and Russia. Like other rare earth elements, this metal is scattered in the ores of other metals, most of it is contained in copper and molybdenum ores. The demand for it is growing as the metal is almost indispensable in the production of high-tech products.
Basically, the extraction of rhenium is reduced to the processing and enrichment of copper sulfide and molybdenum ores. When you save an annual consumption level of 40−50 tonnes, humanity enough world reserves of this metal almost 300 years. Due to its advantages it has earned popularity in metallurgy, nuclear energy, electrical engineering, petrochemical industry.
General information about Rennie
This is the 75th element on the periodic table of Mendeleev — a silvery-white metal, similar in properties to tungsten and molybdenum.
|The proportion||21 g/cm3|
|The specific heat of fusion||34 kJ/mol|
|Atomnaya weight||186,2 g/mol|
|The degree of oxidation||-1, 0, 2, 3, 4, 5, 6, 7|
Alloys of rhenium increase the strength and simultaneously improve the plasticity of steel. Alloying with rhenium, tungsten and molybdenum makes steel alloys krasnoselkii, they copes with repeated heating and cooling without sacrificing strength and durability.
