· JVASP-55696· LiHSeO3

Lithium hydrogen selenite (LiHSeO₃) is an inorganic ceramic compound containing lithium, hydrogen, selenium, and oxygen. This is primarily a research material studied for its potential ferroelectric and nonlinear optical properties, rather than a mature industrial ceramic. The compound belongs to the broader family of lithium-based selenite ceramics, which are investigated for electro-optic devices, optical frequency conversion, and solid-state laser applications where materials with specific dielectric or nonlinear response are required.
