Basic Chromium Sulfate (BCS), also known as Basic Chrome Sulphate or Chromium(III) Sulphate Basic, is a vital chemical compound appearing as a distinctive green powder. With the chemical formula Cr(OH)SO4 and CAS No. 12336-95-7, it stands as a cornerstone in various industrial applications, primarily revolutionizing the leather industry. Our commitment to excellence ensures the supply of high-purity BCS, meeting stringent international standards for performance and safety.

BCS exhibits remarkable properties crucial for its diverse applications. It is readily soluble in water, forming solutions with a pH value typically ranging from 2.5 to 4.0 (for a 1% solution), making it ideal for controlled chemical processes. The product boasts a basic chromium content of 24-26% as Cr2O3, which is critical for its efficacy. Its odorless nature and fine powder form contribute to ease of handling and precise application in industrial settings.

The most prominent application of Basic Chromium Sulfate is in the leather tanning industry. It plays an indispensable role in converting raw animal hides into durable, flexible, and high-quality leather. BCS interacts with collagen fibers in the hide, forming stable cross-links that prevent decomposition, enhance structural integrity, and significantly improve the leather's resistance to water, heat, and wear. This process not only preserves the leather but also imparts a soft, desirable texture and excellent color retention, making it suitable for a wide range of premium products, including automotive leather, fashion items, and upholstery.

Beyond leather tanning, BCS finds valuable applications in other sectors. In the textile industry, it is utilized as a mordant for dyeing fabrics, providing vibrant and stable colors with improved strength and environmental wear resistance. Its ability to remove impurities and contaminants also makes it a valuable agent in certain water treatment processes. Furthermore, BCS can be used in the production of pigments, ceramics, and even as a precursor in chromium electroplating solutions to achieve a durable finish on metal surfaces.

The production of high-quality Basic Chromium Sulfate involves sophisticated processes, often through the reduction of chromate salts with sulfur dioxide or the reaction of chromium oxide with sulfuric acid. A critical aspect of its manufacturing is the complete reduction of hexavalent chromium (Cr VI) to the safer trivalent chromium (Cr III) form, ensuring a product that is less toxic and more environmentally responsible for both tanners and end-users. Our manufacturing facilities adhere to rigorous quality control measures, ensuring consistent chemical properties and superior performance in every batch.

Basic Chromium Sulfate is available in various forms to suit different operational needs, primarily as a fine powder, but also in granulated or liquid forms for specific applications requiring quick and uniform dispersion. The advantages of using BCS are manifold: it leads to improved leather quality with enhanced durability and flexibility, offers a faster tanning process compared to traditional methods, and is considered more environmentally friendly with a reduced impact on water and air quality. Its superior color retention properties are also a significant benefit for high-end leather products.

When considering the purchase of Basic Chromium Sulfate, it is paramount to choose a reliable supplier who prioritizes purity, consistency, and sustainability. Factors such as the basic chromium content, pH, solubility, and the absence of hexavalent chromium are crucial for optimal performance. We, as a dedicated manufacturer, offer competitive price options for bulk orders, ensuring cost-effectiveness without compromising on quality.
