· JVASP-116543· Y3TaO7

Y3TaO7 is a yttrium tantalum oxide ceramic compound belonging to the family of mixed rare-earth transition metal oxides. This material is primarily of research and developmental interest for high-temperature structural applications, where its combination of refractory properties and tantalum's high thermal stability make it relevant for extreme-environment engineering. The material is being investigated for aerospace thermal protection, nuclear reactor components, and advanced refractory applications where conventional ceramics reach their performance limits.
