Argon
Almost one percent of the air you are breathing, and the cheapest way to keep oxygen away from hot metal.
Arsenic
Famous as a poison, but in ultra-pure form it is half of gallium arsenide, the compound behind high-frequency radio…
Diamond (Industrial)
Diamond used not as a gem but as a cutting edge — most of it grown in a press rather than dug out of the ground.
Gallium
A silvery metal that melts in your hand, and the basis of the compound semiconductors in fast chargers, radar and LEDs.
Germanium
The element the very first transistors were made from, now used mainly for infrared lenses and fibre-optic glass.
Hafnium
Zirconium's chemical shadow — always found with it, almost impossible to separate from it, and the opposite of it in a…
Helium
The only element cold enough to keep an MRI magnet superconducting, and the only one light enough to escape Earth's…
High-Purity Quartz
Quartz sand so free of other elements that it can be melted into the crucible a silicon crystal is grown inside.
Indium
A soft metal whose oxide is both transparent and electrically conductive — the invisible wiring on top of every…
Krypton
A rare noble gas, about one part per million of the air, separated only where enough air is already being processed.
Neon
A noble gas so unreactive it forms no compounds at all, separated out of ordinary air in tiny quantities.
Ruthenium
A hard platinum-group metal used in tiny quantities inside hard drives and increasingly in chip interconnects.
Silicon
The second-most-common element in the Earth's crust — ordinary sand — purified until only one atom in a billion is…
Silicon Carbide & Abrasives
Man-made grit — silicon carbide and fused alumina — harder than almost every natural mineral, used to cut and grind…
Tantalum
A dense metal whose oxide layer stores charge extremely reliably, which is why it is in the capacitors of anything that…
Tin
A soft metal with a low melting point, which is why nearly every electrical joint in every device is held together with…
Xenon
The rarest stable gas in the atmosphere — under one part in ten million — and the heaviest thing you can breathe.
