Ferric Oxide, a compound with the chemical formula Fe2O3 and CAS number 1309-37-1, is a fundamental inorganic chemical widely utilized across various industries. Its distinctive red powder appearance is recognized globally, but its true value lies in its meticulously controlled properties and specifications, which are crucial for consistent performance in applications ranging from paints and ceramics to electronics and health supplements. For businesses seeking reliable raw materials, understanding these details is key, and partnering with a reputable supplier like NINGBO INNO PHARMCHEM CO.,LTD. ensures access to high-quality product. The molecular weight of Ferric Oxide is approximately 159.69 g/mol, indicating a stable compound. Its appearance as a 'Red Powder' is a standard descriptor, but specific technical properties are vital for precise applications. For instance, typical specifications include limits on volatile matter at 105°C, typically less than 1%, ensuring minimal moisture content. The solubility in water is also very low, usually less than 0.5%, which is advantageous for applications where water resistance is needed. The pH value of a suspension, generally between 3.5 and 7.0, provides an indication of its stability and compatibility in formulations. Other critical specifications for Ferric Oxide include the remainder of sifting, which is kept below 0.3%, ensuring a fine and consistent particle size. Oil absorption, usually in the range of 15-25 g/100ml, influences its dispersion and rheological properties in paints and coatings. Crucially, the Fe% content, expressed as Fe2O3 dried at 105°C, is typically 97% or higher, confirming its purity and effectiveness as a pigment or chemical component. When you buy ferric oxide CAS 1309-37-1, these detailed technical sheets are readily available from trusted suppliers like NINGBO INNO PHARMCHEM CO.,LTD. Packaging and storage are also important to maintain the integrity of Ferric Oxide. Commonly supplied in 25kg bags, it requires storage in a cool, dry, and ventilated area to prevent degradation. Proper handling ensures that the material's properties are preserved for optimal performance. In essence, Ferric Oxide is a sophisticated chemical product whose utility is amplified by its precise specifications. By understanding these technical details and sourcing from a reliable ferric oxide supplier in China, businesses can confidently integrate this essential material into their production processes, ensuring quality, consistency, and efficiency.
