· JVASP-41798· KNaSmTaO5

KNaSmTaO5 is a mixed-metal oxide ceramic compound containing potassium, sodium, samarium, and tantalum. This is a research-phase material rather than an established commercial ceramic, likely being investigated for its dielectric, ferroelectric, or photonic properties given its complex perovskite-family chemistry. The combination of rare-earth (samarium) and refractory (tantalum) elements suggests potential applications in high-temperature electronics, optical devices, or specialized sensors where conventional ceramics fall short.
