What is Rhenium

Rhenium is a chemical element; it has symbol Re and atomic number 75. It is a silvery-gray, heavy, third-row transition metal in group 7 of the periodic table. With an estimated average concentration of 1 part per billion (ppb), rhenium is one of the rarest elements in the Earth's crust.

Rhenium is a silvery-white metal with one of the highest melting points of all elements, exceeded by only tungsten. It also has one of the highest boiling points of all elements, and the highest among stable elements. It is also one of the densest, exceeded only by platinum, iridium and osmium. Rhenium has a hexagonal close-packed crystal structure, with lattice parameters a = 276.1 pm and c = 445.6 pm.

Its usual commercial form is a powder, but this element can be consolidated by pressing and sintering in a vacuum or hydrogen atmosphere. This procedure yields a compact solid having a density above 90% of the density of the metal. When annealed this metal is very ductile and can be bent, coiled, or rolled. Rhenium-molybdenum alloys are superconductive at 10 K; tungsten-rhenium alloys are also superconductive around 4–8 K, depending on the alloy. Rhenium metal superconducts at 1.697±0.006 K.

In bulk form and at room temperature and atmospheric pressure, the element resists alkalis, sulfuric acid, hydrochloric acid, nitric acid, and aqua regia. It will however, react with nitric acid upon heating.

Make Rhenium and Its Products

Rhenium is mainly produced from the by-products of molybdenum and copper smelting processes. When extracting rhenium, first prepare a rhenium-containing solution from the rhenium-containing raw material. The solution is separated and purified to extract the pure rhenium compound. Then, the hydrogen reduction method, aqueous solution electrolysis method, and halide thermal dissociation method are used to prepare rhenium powder, and then the rhenium powder is processed into materials by powder metallurgy and other methods.

High-temperature Sintering Method

This is one of the commonly used industrial methods, including the general process of powder metallurgy, so it is also called powder metallurgy method. First, rhenium powder is put into a steel mold, pressed into rectangular strips at a pressure of 6MPa, and then pre-sintered in vacuum or hydrogen at 1473K for 1 hour to make it have certain strength, conductivity and to remove some volatile impurities. Finally, the pre-sintered strips are loaded into a furnace at 2973-3123K for high temperature sintering to achieve high density.

Smelting Method

This method uses sintered bars as raw materials, and uses arc melting, electron beam melting and zone melting methods to purify and refine crude rhenium. The rhenium ingot obtained by electron beam melting is a columnar crystal with a purity of 99.99%; the product obtained by zone melting is a rhenium single crystal with spectral purity.

Flotation Method

This is a process that uses differences in the physical and chemical properties of mineral surfaces to separate rhenium minerals. It can separate rhenium minerals from other minerals to obtain pure rhenium materials.

Oxidation Roasting Method and Sulfuric Acid Reduction Method

Both methods are used to extract rhenium from the ore. The oxidation roasting method is to oxidize rhenium ore at high temperature to convert it into rhenium oxide, and then reduce it to metallic rhenium through a reduction reaction. The sulfuric acid reduction method is to leach rhenium ore to obtain a rhenium-containing sulfate solution, which is then reduced to metallic rhenium through a reduction reaction.

Electrolytic Method and Chemical Reduction Method

Both methods can be used for rhenium refining. Electrolysis is to deposit rhenium on the cathode by electrolysis of the rhenium-containing electrolyte, and then dry and sinter it to obtain pure rhenium. Chemical reduction method, on the other hand, is to react the rhenium-containing chemicals with a reducing agent to reduce rhenium to rhenium metal, and then obtain pure rhenium through drying, sintering and other treatments.
