Rising demand in the post-Covid 19 economic boom. Global production of hafnium in various grades is currently estimated to be 70-80 tons. "This is a small number compared to other technology metals such as gallium or indium, of which 700 and 1,000 tons respectively are available per year," explains Giese.
