Rhenium foil,Rhenium sheet
Purity : 99% min
Rhenium was named after "Rhenus", the Latin name for the Rhine. It is a rare element
(abundance 4 x 10 4 ppm in the earth's crust) and does not occur in quantity in any ore.
It is found in ores which contain molybdenum from which it can be readily recovered. The
metal is obtained by hydrogen reduction of the potassium perrhenate salt, obtained by
precipitation of the perrhenate ion (ReO4) - from an oxidised solution.
Rhenium is a silvery coloured metal which resists corrosion and oxidation but slowly
tarnishes in moist air. It is soluble in nitric and sulphuric acids. Applications for the metal
include its use as an alloying element with tungsten, the resulting alloy having a very high
electrical resistance making it suitable for electrical filaments. Rhenium has a very high
melting point and is used in high temperature thermocouples, electrical contacts
and thermistors.
