Preparation

Americium can be obtained from the reaction of metallic americium with nitrogen or ammonia at 750–800°C:²

It can also be obtained from the reaction of americium trihydride (AmH3) with nitrogen at 750 °C:⁴

Chemical properties

Americium nitride reacts with cadmium chloride to form americium trichloride:⁵
