Lithium carbonate is a salt which comes in form of a colorless solid at standard conditions (the slight coloration of the sample shown above comes from impurities). Lithium carbonate is an important industrial chemical. It is used in metallurgy, in the production of certain types of glass, ceramics, batteries and cement. This compound has historically also been used to treat bladder stones, also for treating mania, depression, headaches and similar disorders. Since lithium can change the color of flames to a characteristic red color, it is also used in pyrotechnics for creating various effects.

Lithium carbonate usually isn't easily obtainable. It can be synthesized from pure lithium, which first forms lithium hydroxide in a reaction with water. The hydroxide then reacts with carbon dioxide to form lithium carbonate. Alternatively, it can also be ordered from chemical selling companies.
