Retaining its crystal`line structure at temperatures up to its melting point,Rhenium is gray to black in powder form,silvery-white and lustrous as a solid,it does not occur naturally.Rhenium has one of the highest densities,exceeded only by platinium,iridium,and osmium.Only tungsten has higher melting points.Rhenium has good wear resistance and it can withstand arc corrosion. Rhenium s range of valences exceeds that of all other elements.Rhenium Powder Purity 99.99 Percent Appearance powder Color Grey - black Density 21.02g/cm3 Melting point 3180 & 176C Boiling point 5900& 176C Inner Packing by vacuum bag Outter Packing by vacuum bag,250g/bag, 1000g/bag,2000g/bag Min trial order 250grams Applications 1.Rhenium wire a for thin filaments 2.Because of its high density,it do not deform easily when struck and do not expand or contract to a significant degree` when heated or cooled. So it used for Space Craft Thrusters 3.A commonly used thermocouple in high-temperature devices consists of a rhenium-tungsten ally that melts at 2,200 degree`s Celsius. 4. For Electrical Contacts 5.Chemical Catalysts 6. rhenium powders get used for optical coatings and corrosion-resistant coatings for metal,etc.
