Antimony Properties and reactions Britannica

Antimony Antimony Properties and reactions The most stable form of elemental antimony is a brittle, silvery solid of high metallic lustre. Electrolytic deposition of antimony under certain conditions produces an unstable, amorphous form called "explosive antimony," because, when bent or scratched, it will change in a mildly explosive manner to the more stable, metallic form.
