Metals, such as HAFNIUM POWDER (reactivity similar to zirconium), are reducing agents and tend to react with oxidizing agents. Their reactivity is strongly influenced by their state of subdivision: in bulk they often resist chemical combination; in powdered form they may react very rapidly. Thus, as a bulk metal it is somewhat unreactive, but ...Web

Hafnium is the 45th most abundant element on Earth, making it only take up 3.3 parts per million of Earth's crust by weight. Hafnium is a transition metal, meaning it has the potential to have many oxidation states and is a good conductor of electricity. Hafnium is also pyrophoric which means it can ignite spontaneously when exposed to air ...Web
