· JVASP-41560· Th3O2

Th₃O₂ is a thorium oxide ceramic compound belonging to the rare earth and actinide oxide family. While not widely commercialized, this material is primarily studied in nuclear fuel research and advanced ceramics development due to thorium's potential as an alternative nuclear fuel and its high thermal stability. Engineers consider thorium-based oxides for extreme-temperature applications and nuclear fuel cycles where traditional uranium oxides face limitations, though regulatory and proliferation concerns significantly restrict practical industrial deployment.
