1. Pharmaceuticals

• Mood Stabilizer: Lithium carbonate is widely used in the pharmaceutical industry for the treatment of bipolar disorder as a mood stabilizer. It helps in reducing the frequency and severity of manic and depressive episodes.
• Active Pharmaceutical Ingredient (API): It is used as an active ingredient in medications that manage mood disorders and certain neurological conditions.

2. Construction

• Alkali-Silica Reactivity (ASR) Inhibitor: Lithium carbonate is used in concrete to control alkali-silica reactivity, which can cause cracking and deterioration in concrete structures. It helps in extending the lifespan and durability of concrete, especially in structures exposed to harsh environmental conditions.

3. Chemicals Synthesis

• Precursor to Other Lithium Compounds: Lithium carbonate is a crucial raw material for producing other lithium compounds, such as lithium hydroxide, lithium chloride, and lithium metal, which are used in various industrial applications.
• Catalyst in Polymer Production: It can be used as a catalyst in certain polymer production processes, helping to control the polymerization reactions and improve product quality.

4. Metal Treatment

• Flux in Metallurgical Processes: It is used as a flux in metallurgical processes, especially in the production of ceramics, to lower the melting points of metal oxides and facilitate easier removal of impurities.
• Lithium Metal Production: Lithium carbonate serves as a precursor in the production of lithium metal, which is used in specialized applications, including some types of batteries and in the synthesis of organic compounds.

5. Polymers & Resins

•  Polymerization Catalyst: In the production of synthetic rubber and plastics, lithium carbonate can act as a catalyst for the polymerization process, enhancing product properties. • Specialty Chemicals: Used as a reagent in the synthesis of various specialty chemicals, where lithium plays a role in catalysis or as a component of the chemical structure.
