What Happens if Rhenium Is Alloyed to Niobium, Tungsten, and Tantalum?

0 Comment

Rhenium is added to high-temperature superalloys that are used to make jet engine parts, using 70% of the worldwide rhenium production. Another major application is in platinum–rhenium catalysts, which are primarily used in making lead-free, high-octane gasoline. Nickel-based superalloys have improved creep resistance with the addition of rhenium. Alloys normally contain 3% or 6% rhenium. […]

Structure and Applications of Hafnium Oxide

0 Comment

Hafnium oxide is the inorganic compound of formula HfO2. Also known as hafnia, this colorless solid is one of the most common and stable compounds of hafnium. It is an electrical isolator with a band gap of 5.3 ~ 5.7 eV. Hafnium dioxide is an intermediate in some processes that give hafnium metal. Hafnium oxide […]
