Lithium Carbonate

Lithium Carbonate Powder is a finely ground form of lithium carbonate (Li₂CO₃), commonly used in industries requiring high-purity, easily dispersible lithium sources, such as battery manufacturing, ceramics, pharmaceuticals, and glass production. The powder form of lithium carbonate is particularly advantageous for applications where fast dissolution or easy blending with other materials is desired.

Applications:

Battery Manufacturing: Lithium carbonate powder is a crucial precursor in producing cathode materials for lithium-ion batteries, such as lithium cobalt oxide (LiCoO₂), lithium nickel manganese cobalt oxide (NMC), and lithium iron phosphate (LiFePO₄). Its fine particle size facilitates homogeneous mixing in electrode formulations.

Ceramics and Glass: In ceramics, lithium carbonate powder is used as a flux, lowering the melting point of materials and enhancing the strength and finish of glazes. In glass manufacturing, it is added to improve strength and reduce melting temperatures.

Pharmaceuticals: Used in a controlled form, lithium carbonate is employed in treating bipolar disorder as a mood stabilizer. The fine powder is useful for precision dosing and creating uniform tablet blends.

Aluminum Smelting: Lithium carbonate powder is also used in aluminum production, where it helps reduce the melting point of aluminum oxides and improves electrolytic efficiency.

Handling and Storage:

Storage: Store in a dry, cool environment to prevent clumping and ensure quality. Avoid exposure to acidic vapors, which can lead to mild decomposition.

Safety Precautions: Avoid inhaling the powder and use personal protective equipment (PPE), including gloves, safety goggles, and dust masks when handling large amounts.
