Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa).

Lithium orthosilicate is a compound with the chemical formula Li4SiO4. It is a white ceramic compound, which melts congruently at a temperature of 1,258 °C (2,296 °F).[1]

Lithium orthosilicate is of primary interest towards carbon dioxide capture, as this compound reacts with CO2 at elevated temperatures to form lithium carbonate, and has been implemented in limited scale in such applications.[2] Further applications of Li4SiO4 include solid electrolytes for lithium-ion batteries, specifically

solid state batteries,[3] and tritium breeding materials, as a component of the breeding blanket for planned fusion energy systems such as ITER.[1]
