Custom Manufacturing, Project Outsourcing, your Trusted Partner from China
For procurement managers and R&D scientists in the chemical industry, understanding the precise technical specifications of a raw material is non-negotiable. Iron Oxide Black (CAS 12227-89-3), a staple inorganic pigment, is no exception. As a leading iron oxide black manufacturer, NINGBO INNO PHARMCHEM CO.,LTD. is dedicated to providing detailed technical information to ensure our clients can confidently integrate our product into their formulations.
The fundamental chemical identity of Iron Oxide Black is its molecular formula, Fe3O4. This compound, also known as magnetite, forms the basis of its characteristic black color and magnetic properties. The relative density typically ranges around 5.18 g/cm³, and its melting point is exceptionally high, around 1594°C, underscoring its thermal stability in many industrial processes.
Key physical properties that buyers look for include its appearance, which is a fine black powder. Critical quality indicators often specified include: the content of Fe2O3 (or total iron content), typically above 95% for high-grade products; a low percentage of water-soluble salts and volatile matter, ensuring purity and stability; minimal sieve residue (e.g., ≤ 0.5% on 325 mesh) to guarantee fine particle size and good dispersion; a specific pH range, usually between 5-8, indicating its chemical neutrality; and oil absorption, which influences its behavior in different formulations, often in the range of 15-25 ml/100g. These parameters are crucial for achieving consistent performance when using it as a colorant for coatings or in plastics.
Furthermore, Iron Oxide Black exhibits excellent light and atmospheric resistance, a significant advantage over many organic pigments. It is insoluble in water and alcohol but soluble in concentrated acids and hot strong acids, a property to be mindful of during handling and formulation. Its good alkali resistance makes it suitable for cement-based products. When sourcing from a reputable iron oxide black supplier in China, you can expect these specifications to be reliably met, ensuring consistent product performance.
For those interested in specialized applications, such as cosmetics, grades with extremely low impurity levels are available. This is particularly relevant for companies seeking cosmetic grade iron oxide black for sale. Ensuring these high-purity standards requires rigorous quality control and advanced manufacturing processes.
NINGBO INNO PHARMCHEM CO.,LTD. is committed to transparency and quality. We provide comprehensive technical data sheets and support to help you integrate our Iron Oxide Black seamlessly into your operations. We believe that understanding the technical nuances is the first step to a successful partnership.
