Почему это важно для материаловедения
An aero-engine turbine blade sits in gas hotter than the alloy's melting point and survives because of rhenium, hafnium and a ceramic coating. That is why a few tonnes of a by-product metal can be a national-security question.

Aluminium
A light silvery metal made by passing an enormous electric current through dissolved bauxite — which is why people…
Cobalt
A hard, bluish metal that keeps a battery's cathode stable so it does not overheat, and that holds its strength when…
Gallium
A silvery metal that melts in your hand, and the basis of the compound semiconductors in fast chargers, radar and…
Hafnium
Zirconium's chemical shadow — always found with it, almost impossible to separate from it, and the opposite of it in…
Nickel
A silvery metal that resists rust, which is why it goes into stainless steel — and, more recently, into the cathodes…
Rhenium
One of the rarest metals in the crust, recovered from molybdenum roasting, and the ingredient that lets a jet turbine…
