lintterit

Lintterit is a synthetic lithium-titanium-silicate ceramic material developed for research in solid-state electrolytes. It crystallizes as a resilient, open-framework oxide with potential high lithium-ion conductivity at moderate temperatures. The material is noted for thermal stability and chemical robustness compared with conventional liquid-electrolyte systems.

The name Lintterit was coined by researchers from the Lincrest Institute in 2016; it combines elements of the laboratory's name with the common mineral-ending -ite, signaling its crystalline character.

Chemically, Lintterit comprises lithium, titanium, and silicon-oxygen frameworks, typically with trace metals such as aluminum or iron that can modulate conductivity. The crystal structure forms a tetrahedral silicon-oxygen network interlinked with LiO4 and TiO6 units, producing an open, 3D framework.

Synthesis is achieved by high-temperature solid-state reaction or sol-gel processing, followed by controlled annealing to improve crystallinity. Natural occurrences have not been documented, and all known samples are laboratory-synthesized.

Physical properties include a Mohs hardness of about 5.5–6.5, a density around 3.8–4.2 g/cm3, and a pale luster. Ionic conductivity measurements vary with dopants and microstructure, with research focusing on achieving stable ionic mobility at room temperature or modest temperatures.

Applications for Lintterit are primarily in energy storage research, particularly as a solid-state electrolyte or interfacial material in lithium-based batteries. It has also attracted interest for doped variants that exhibit luminescent or optoelectronic properties.

Safety and handling follow standard laboratory protocols for lithium-containing ceramics; chemical stability reduces flammability concerns, but dust and inhalation risks require appropriate PPE.
