· JVASP-9777· SrLi2Ta2O7

SrLi2Ta2O7 is an inorganic ceramic compound combining strontium, lithium, and tantalum oxides, belonging to the family of complex metal oxides with potential ferroelectric or dielectric properties. This material is primarily investigated in research and development contexts for applications requiring high-performance ceramics, particularly in optoelectronics, solid-state ion conductors, or specialized dielectric devices. Its tantalum content and layered perovskite-like structure make it a candidate for next-generation electronic ceramics where conventional materials reach performance limits.
