INTRODUCTION OF SCANDIUM, ZIRCONIUM AND

Hafnium in aluminum alloys has a stronger re ning e ect than zirconium, which is explained by its more pro-nounced metallic properties; additionally, hafnium is a good absorber of thermal neutrons. Addition of 1% hafnium in aluminum leads to the production of aluminum superalloys with metal grain size of 40{50 nm. Here, not only alloy Get price

Zirconium

Commercial non-nuclear grade zirconium typically contains 1–5% of hafnium, whose neutron absorption cross-section is 600x that of zirconium. Hafnium must therefore be almost entirely removed (reduced to 0.02% of the alloy) for reactor applications. Zirconium Alloy – Zircaloy – 4 Get price

Why Is Zirconium Used In Nuclear Reactors?

Initially, zirconium was not considered a suitable material for use in the nuclear industry, because studies have shown that zirconium's effect on thermal neutron absorption can affect the efficiency of nuclear reactors. Later, researchers at the Oak Ridge Institute found that 2.5% of the hafnium in zirconium was responsible for its large thermal neutron capture cross-section. Get price
