FAQs
1. What is the significance of the 99.998% purity specification?
The 99.998% purity (metals basis excluding Ca) indicates that this lithium carbonate contains only 0.002% metallic impurities, with calcium specifically limited to below 20ppm. This level of purity is critical for applications where even trace amounts of contaminants could affect results, such as in semiconductor manufacturing or high-precision analytical chemistry.
2. How does the Puratronic™ grade differ from standard laboratory grades?
Puratronic™ represents the highest purity tier in our product lineup, featuring significantly lower impurity levels compared to standard grades. While typical laboratory-grade lithium carbonate may contain hundreds of ppm of various metals, this grade maintains impurities at parts-per-million levels, with calcium specifically controlled below 20ppm. This makes it suitable for the most demanding applications where standard grades would introduce unacceptable contamination.
3. Can this product be used for lithium-ion battery research?
While this ultra-pure lithium carbonate could technically be used in battery research, it’s important to note that battery applications typically require different lithium compounds like lithium hydroxide or lithium hexafluorophosphate. The Puratronic™ grade is more commonly employed in applications where the carbonate form is specifically needed, such as in certain ceramic formulations or as a precursor for other high-purity lithium compounds.
4. What storage conditions are recommended to maintain product integrity?
To preserve the ultra-high purity of this lithium carbonate, store it in a tightly sealed container in a cool, dry environment. Exposure to moisture should be minimized as lithium carbonate is hygroscopic and can absorb water from the air, potentially altering its composition. For long-term storage, consider using desiccants in the storage area and avoid temperature fluctuations that could cause condensation.
5. Is this product compatible with standard laboratory glassware?
Yes, this lithium carbonate powder is fully compatible with standard borosilicate glass laboratory equipment. However, when working with such high-purity materials, it’s recommended to use dedicated glassware that has been thoroughly cleaned with acid washing to prevent cross-contamination from residual impurities in previously used equipment. Always rinse with deionized water before use to maintain the product’s purity during handling.
