· JVASP-50635· Y2Th5O13

Y2Th5O13 is a rare-earth and thorium oxide ceramic compound belonging to the family of mixed-metal oxides. This material is primarily of research and development interest for high-temperature applications, as the yttrium-thorium oxide system offers potential thermal stability and refractoriness in extreme thermal environments. Engineers consider this material class for specialized applications requiring thermal resistance and chemical inertness at elevated temperatures, though it remains less common than conventional refractory oxides.
