· JVASP-54723· YH3O3

YH3O3 is a rare-earth yttrium oxide ceramic compound belonging to the family of yttrium-based ceramics, which are typically researched for their thermal stability and refractory properties. While YH3O3 appears to be a specialized or experimental composition, yttrium oxide ceramics are pursued in advanced applications requiring materials that resist thermal shock and chemical attack at elevated temperatures. Engineers considering materials in this family would evaluate them for specialized thermal, optical, or structural applications where conventional oxides reach performance limits.
