설명

일반 설명

Lithium carbonate (Li₂CO₃), a lithium salt, is a white monoclinic crystalline solid. Its industrial preparation has been described. In laboratory, it can be synthesized by reacting carbon dioxide gas with a lithium hydroxide solution.

애플리케이션

Lithium carbonate (Li₂CO₃) may be used in the following studies:

• As a precursor in the preparation of LiFe_1-yV_yPO₄ solid solutions.
• As a starting reagent for the synthesis of various lithium salts (lithium chloride and lithium bromide).
