Trace … Plutonium(IV) oxide, or plutonia, is a chemical compound with the formula PuO2. This high melting-point solid is a principal compound of plutonium. It can vary in color from yellow to olive green, depending on the particle size, temperature and method of production. See more PuO2 crystallizes in the fluorite motif, with the Pu centers organized in a face-centered cubic array and oxide ions occupying tetrahedral holes. PuO2 owes its utility as a nuclear fuel to the fact that vacancies in the … See more Plutonium spontaneously oxidizes to PuO2 in an atmosphere of oxygen. Plutonium dioxide is mainly produced by calcination of … See more The behavior of plutonium dioxide in the body varies with the way in which it is taken. When ingested, most of it will be eliminated from the body quite rapidly in body wastes, but a small part will dissolve into ions in acidic gastric juice and cross the blood barrier, … See more • Space Radioisotope Power Systems Safety See more Plutonium dioxide is a stable ceramic material with an extremely low solubility in water and with a high melting point (2,744 °C).
