Hafnium Oxide and Its Structure And Applications Hafnium oxide is the inorganic compound of the 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 bandgap of 5.3 ~ 5.7 eV. Hafnium dioxide is an intermediate in some […]

Why Is Zirconium A Transition Metal? When of sufficient purity, zirconium is soft and ductile. Zirconium a transition metal has good corrosion resistance and low absorption capacity for thermal neutrons. These properties are desirable in materials used for certain parts of nuclear reactors. The great increase in the production of zirconium since 1945 has been […]

What Hafnium Is Used For? Hafnium occurs in zirconium ores. Because this metal must be removed from “reactor-grade” zirconium, the production of hafnium is largely dependent on zirconium production, as discussed later. Its melting point is 4032℉. However, it has not been available in sufficiently large quantities to have any extensive elevated-temperature applications other than […]
