Lithium orthosilicate
Lithium orthosilicate is a compound with the chemical formula LiSiO. It is a white ceramic compound, which melts congruently at a temperature of . Lithium orthosilicate is of primary interest towards carbon dioxide capture, as this compound reacts with CO at elevated temperatures to form lithium carbonate, and has been implemented in limited scale in such applications. Further applications of LiSiO include solid electrolytes for lithium-ion batteries, specifically solid state batteries, and tritium breeding materials, as a component of the breeding blanket for planned fusion energy systems such as ITER.
