PaO3

ceramic

· JVASP-41813· PaO3

PaO3 is a rare-earth oxide ceramic compound in the perovskite or pyrochlore family, likely containing protactinium or another actinide/rare-earth element. This material is primarily investigated in nuclear fuel, solid-state electrolyte, and advanced refractory applications rather than in widespread commercial use; its selection depends on specific functional properties such as thermal stability, radiation resistance, or ionic conductivity that justify the cost and handling complexity of rare or radioactive constituents.
