🔹 Description: Lithium Carbonate (Li₂CO₃) – 98% Purity
- Chemical Formula: Li₂CO₃
- Molecular Weight: 73.89 g/mol
- Appearance: White, odorless crystalline powder
- Purity: 98% (industrial or technical grade; not pharmaceutical grade)
- CAS Number: 554-13-2
🔹 Applications / Uses of Lithium Carbonate (98% Purity)
This purity level is typically used in industrial, ceramic, and battery-related processes. Common applications include:
1. Battery Industry
- Used as a raw material in the production of lithium-ion battery cathodes, such as LiCoO₂, LiFePO₄, and LiNiMnCoO₂ (NMC).
- Often used in electric vehicles (EVs) and energy storage systems.
2. Ceramic and Glass Industry
- Acts as a flux to reduce melting point.
- Improves thermal shock resistance in ceramic glazes and specialty glass.
3. Aluminum Production
- Used as an additive in alumina electrolysis to reduce melting point and energy consumption.
4. Grease and Lubricants
- Used to manufacture lithium-based greases, known for their high temperature stability.
5. Air Purification
- Absorbs CO₂ in enclosed environments (e.g., submarines or space shuttles).
⚠️ Note: 98% purity is not suitable for pharmaceutical use (e.g., psychiatric medications), which requires ≥99.5% purity and stricter impurity limits.
