CLASSIFICATION OF HAFNIUM MINERALS

 

Hafnium (Hf) is contained in the following mineral:

• • Zircon (1-4% HfO2)

  • Baddeleyite (4-6% HfO2)

Hafnium is contained in the following minerals too:

• Thortveitite

• Eudialyte

• Zirkelite

• Loparite

They produce and sell hafnium:

• Allegheny Techno logies Incorporated (USA)

• Western Zirconium (USA)

• Cezus (France)

Hafnium is contained in the varieties of zircon:

• • Hafnon (70-72,5 % HfO2)

• Hafnian Zircon (31 % HfO2)
