Information

Metal rhenium and its alloys can be used to make tap water pen tips and high-temperature thermocouples, and be used as catalysts in alcohol dehydrogenation, ammonia synthesis and sulfur trioxide production from sulfur dioxide. Alloys containing 90% tungsten, 1% vanadium, and 9% rhenium can withstand high temperatures. Since rhenium is scattered and expensive, its practical application has yet to be developed.

high purity rhenium prices

1. Rhenium is mainly used as a catalyst in the petroleum industry.
2. Rhenium has high electron emission performance and is widely used in radio, television and vacuum technology.
3. Rhenium has a very high melting point and is a major high temperature instrument material. At the same time, rhenium-containing alloys are also used in the manufacture of heat-resistant parts of aero-engines, and about 80% of the world's rhenium is used in the production of aero-engines.
4. Rhenium and Rhenium alloys can also be used as electronic tube components and ultra-high temperature heaters to evaporate metals.
5. The tungsten-rhenium thermocouple does not soften at 3100 °C. Adding 25% rhenium to the tungsten or molybdenum alloy can increase the ductility. Rhenium is used as a high-temperature coating on rockets and missiles. Instruments and high-temperature components used in spacecraft such as heat shields, arc discharges, and electrical contactors require rhenium.
6. Metal rhenium and its alloys can be used to make tap water pen tips and high temperature thermocouples. It is used as a catalyst in chemical industry such as alcohol dehydrogenation and ammonia synthesis. Alloys containing rhenium are resistant to high temperatures. Due to the scattered presence of rhenium, it is expensive, and practical applications have yet to be developed. It is also used to make electric filaments, shells for artificial satellites and rockets, and protective panels for atomic reactors.
