· JVASP-140668· Y2Th8O19

Y2Th8O19 is a rare-earth and thorium-based ceramic compound that combines yttrium and thorium oxides in a mixed-oxide ceramic matrix. This material belongs to the family of high-temperature refractory ceramics and is primarily investigated for extreme thermal environments where conventional oxides reach their performance limits. It is notable for its potential thermal stability and resistance to thermal shock, making it a candidate for advanced refractory applications, though it remains largely a research-phase material with limited commercial deployment compared to more established oxide ceramics.
