Product Overview
Barium Carbonate 99% AR is a high-purity analytical reagent designed for precision laboratory applications. This fine, white crystalline powder offers exceptional chemical stability and consistent performance in titrations, precipitation reactions, and specialized glass formulations. With a guaranteed 99% purity level, it meets stringent AR-grade specifications, ensuring reliable results in quantitative analysis. The compound’s low solubility in water (0.02 g/L at 20°C) contrasts with its complete solubility in dilute acids, making it ideal for controlled reaction environments. Each batch undergoes rigorous quality testing to confirm its non-hygroscopic nature and absence of heavy metal impurities. The 500g packaging provides an optimal balance between bulk requirements and freshness preservation, with a resealable container to maintain purity during storage. Its molecular formula (BaCO₃) and molar mass (197.34 g/mol) remain constant across applications, delivering predictable stoichiometric behavior in chemical processes.
FAQs
1. What is the exact particle size range of this Barium Carbonate powder?
The typical particle size distribution falls between 1-5 microns, though slight variations may occur between production batches. For applications requiring specific particle sizes, we recommend sieve analysis prior to use.
2. Can this product be used in food-grade applications despite its AR classification?
No, this AR-grade Barium Carbonate is specifically formulated for laboratory use and contains technical-grade processing aids that make it unsuitable for food, pharmaceutical, or cosmetic applications.
3. What type of container material is recommended for long-term storage?
Store in the original high-density polyethylene container or transfer to a glass bottle with a PTFE-lined cap. Avoid metal containers as trace impurities may react with the carbonate over extended periods.
4. How does the reactivity compare between this AR grade and commercial-grade Barium Carbonate?
This 99% AR grade exhibits 15-20% higher reaction rates in standard acid-base titrations compared to commercial grades (typically 95-97% purity) due to reduced inert filler content and tighter control over crystalline structure.
5. What’s the typical moisture content in this product as shipped?
The as-shipped moisture content is maintained below 0.1% by weight through controlled packaging processes, with each batch verified via Karl Fischer titration before release.
