ceramic

· JVASP-86448· EuTaO4

EuTaO₄ is an oxide ceramic compound composed of europium and tantalum, belonging to the rare-earth tantalate family of materials. This is primarily a research-phase ceramic studied for its potential in high-temperature and photonic applications, particularly in contexts where rare-earth doping or tantalate-based ceramics offer advantages such as high refractive index, thermal stability, or luminescent properties. The material represents exploration within the broader class of complex oxide ceramics that are candidates for specialized optical, electronic, or structural applications in demanding environments.
