Hafnium
Separated laboriously from zirconium streams, hafnium serves three strategic niches: neutron-absorbing control rods for Gen-III+ and SMR reactors, creep-resistant Ni-based turbine alloys, and high-κ HfO₂ gate dielectrics that now sit in >90 % of sub-10 nm CMOS chips. Annual availability is only a few hundred tonnes; prices react instantly to aerospace build rates and to zircon-sand output shifts in Australia, South Africa and Mozambique.
Supply Dynamics
-
Orano (France) and ATI (USA) refine >70 % of global sponge; ATI’s 2022–25 capacity lift only adds tens of tonnes.
-
Feedstock tied to zircon by-product flows—any slump in ceramics demand pinches Hf.
-
Chinese toll refiners supply spot volumes but face export-licence uncertainty.
-
Strategic stockpiles for naval reactors smooth utility offtake.
-
Purity upgrades (nuclear vs. semiconductor) dictate price premia rather than tonnage.
Demand Dynamics
-
Commercial‐aircraft and rocket-engine orders dictate super-alloy melt programmes.
-
SMR roll-out lifts nuclear-grade sponge call-offs after 2028.
-
Foundry migration to 2 nm logic sustains HfO₂ >12 % CAGR through 2030.
-
Additive-manufactured super-alloy powders need hafnium for grain-boundary strength.
-
No recycling stream yet; scrap retention in alloys limits secondary flow.
