· JVASP-38333· NdDy3

NdDy3 is a rare-earth ceramic compound containing neodymium and dysprosium, belonging to the family of rare-earth oxides or intermetallic ceramics. This material is primarily investigated for high-temperature structural and functional applications where thermal stability and mechanical integrity are critical, particularly in aerospace and advanced energy systems. The combination of neodymium and dysprosium imparts enhanced thermal properties and oxidation resistance compared to single rare-earth phases, making it a candidate material for thermal barrier coatings, refractory applications, or specialized electronic devices in extreme operating environments.
