Lithium Carbonate
High Stability: Lithium carbonate maintains excellent stability under atmospheric conditions without hygroscopicity, ensuring long-term storage integrity and straightforward handling.
Controlled Solubility Profile: It exhibits limited water solubility, characterized by an inverse solubility profile where dissolution decreases with rising temperature, suitable for applications requiring minimal aqueous interaction.
Thermal Resilience: Possessing a melting point of 618°C, the compound demonstrates exceptional thermal endurance for high-temperature industrial processes.
Broad Functional Utility: It serves critical roles in lithium-ion battery cathode production, ceramic glaze formulations, and as a psychotropic medication for bipolar disorder management.
Lithium carbonate (Li₂CO₃) forms as colorless monoclinic crystals or a white powder with a density of 2.11. It exhibits stability in air and is non-hygroscopic. The compound melts at 618°C and displays low solubility in water, which further decreases with increasing temperature.

Industrial-grade lithium carbonate is mainly utilized in the synthesis of lithium compounds, including lithium chloride and lithium bromide. It also functions as a lithium oxide precursor in the manufacturing of enamel, glass, and ceramic glazes. In aluminum electrolysis processes, its addition to electrolytic cells enhances current efficiency while reducing internal resistance and operating temperature. Within the pharmaceutical sector, it is commonly prescribed for managing manic episodes and stabilizing mood fluctuations in schizophrenia patients.
