Chemical compound

Uranium monophosphide is a compound of uranium and phosphorus, synthesized from heating metal uranium and white phosphorus:

4 U + P4 → 4 UP

It is a potential nuclear fuel.

In air, a thin glassy surface layer protects the compound from oxidation; over the course of months after synthesis, this layer develops a metallic sheen.
