Li₂CaTa₂O₇ is a complex oxide ceramic composed of lithium, calcium, and tantalum. This material belongs to the family of ternary oxides and is primarily of research interest rather than an established commercial ceramic, with potential applications in electronic and photonic devices where tantalum-containing ceramics offer high refractive index and chemical stability. The compound's structure and composition make it a candidate for dielectric applications, optical coatings, and potentially as a host material for rare-earth dopants in luminescent or laser ceramics, though engineering use remains largely in the development phase.
