General description
Barium nitrate (Ba(NO₃)₂) is a white crystalline inorganic compound with high purity (99.999% trace metals basis). It is highly water soluble. Upon thermal decomposition, it releases oxygen, acting as a strong oxidizing agent. Due to its ability to consistently supply Ba²⁺ ions and promote oxidation reactions, it is widely used in the synthesis of advanced ceramics, magnetic nanocomposites, and catalytic materials. Its solubility in aqueous media facilitates its use in solution-based fabrication techniques, including sol-gel and co-precipitation methods.
Application
Barium nitrate (Ba(NO₃)₂) is used as a precursor:
- For surface modification of the electrode to enhance its oxygen reduction reaction (ORR) performance.
- In the synthesis of hard magnetic phase BaFe₁₂O₁₉/NiFe₂O₄ nanocomposite via co-precipitation method.
Features and Benefits
- The ultra-high purity of 99.999% ensures that no impurities interfere with the combustion process, resulting in vibrant colours and consistent performance in pyrotechnic displays.
- Low metal impurities minimize the introduction of contaminants during synthesis, leading to higher yields and better quality of the final products.
