Hafnium Facts
Know More
Hafnium does not exist in nature on its own, but is combined with zirconium to form minerals Hafnium is found in the Earth's crust at around 58 parts per million It reacts in air and forms a film to protect the sample Because of this, hafnium is very resistant to corrosion A very fine sample of hafnium can spontaneously combust in air
