· JVASP-35097· Th2HN3

Th2HN3 is a thorium-based ceramic compound, likely a thorium hydride nitride or mixed hydride-nitride phase. This material belongs to the family of refractory and nuclear-related ceramics that incorporate thorium, an actinide element with historical applications in high-temperature and radiation-resistant engineering. While not a mainstream commercial material, thorium ceramics are investigated in nuclear fuel development, refractory applications requiring extreme temperature stability, and specialized aerospace or defense contexts where radiation resistance and thermal performance are critical.
