· JVASP-9783· Li2TiSiO5

Li2TiSiO5 is an oxide ceramic compound combining lithium, titanium, and silicon—a composition of interest primarily in materials research rather than established commercial production. This material belongs to the family of lithium silicates and titanium-containing ceramics, which are investigated for applications requiring low thermal expansion, chemical durability, and high-temperature stability. While not yet a mainstream engineering material, compounds in this class show promise in specialized thermal management, advanced refractories, and functional ceramics where lithium's electrochemical properties or the synergistic effects of titanium and silicon oxides could provide advantages over conventional alternatives.
