Lithium carbonate (Li2CO3, CAS 554-13-2) is a white inorganic lithium salt. Technical grades are used as a flux in glass, ceramics, and porcelain glazes, as an additive in cement and refractories, as a constituent of arc-welding electrode coatings, in aluminum production, and as a precursor for other lithium compounds and battery cathode materials.

Frequently Asked Questions
What is technical grade lithium carbonate?
Technical-grade lithium carbonate (Li2CO3, CAS 554-13-2) is a white inorganic lithium salt meeting industrial-use purity rather than battery-cathode specification. It is used as a flux in glass, ceramics, and glazes, as an additive in cement and refractories, in arc-welding electrode coatings, in aluminum production, and as a precursor for other lithium compounds.
What is the difference between technical grade and battery grade lithium carbonate?
Both share the same compound and CAS 554-13-2, but battery grade is refined to much tighter limits on metallic and anionic impurities for cathode synthesis, whereas technical grade targets industrial uses such as glass, ceramics, and welding where those limits are not required. Confirm impurity specs on the CoA against your process needs.
What is lithium carbonate used for in glass and ceramics?
It acts as a flux that lowers the melting point and improves melt flow in glass, frits, and porcelain glazes, and as a set-control additive in cement and high-alumina refractory systems. It is also a constituent of arc-welding electrode coatings.
What is the CAS number and HS code for lithium carbonate?
Lithium carbonate carries CAS 554-13-2 with formula Li2CO3, and classifies under HS code 2836.91 (lithium carbonates). Reference these on import documentation and the Certificate of Analysis.
Does RawSource supply technical grade lithium carbonate in bulk?
RawSource distributes technical-grade lithium carbonate in bulk industrial quantities for glass, ceramic, refractory, and welding applications. A Certificate of Analysis and Safety Data Sheet ship with each order; request both with a bulk quote for your target volume.
What is the REACH and TSCA regulatory status of Lithium Carbonate (Li2CO3)?
Lithium Carbonate (Li2CO3) (CAS 554-13-2) is subject to U.S. TSCA Inventory requirements; supplying it into the EU requires valid REACH registration ((EC) No 1907/2006). RawSource cannot verify a third-party supplier's registrations — buyers should require documented TSCA and REACH compliance for their jurisdiction and volume (EC 209-062-5).
