The fire-stopper

Antimony

A brittle, silvery metalloid that most people have never heard of and almost everyone relies on. It keeps plastics from burning, hardens lead in batteries, and turns up in ammunition and chips.

Why it matters

  • Flame retardants account for about half of global demand.
  • China controls most of the world's mined and refined supply and restricted exports in 2024.
  • Listed as a critical mineral by the United States and the European Union.
