Cobalt Tetroxide (molecular formula: Co₃O₄; CAS number: 1308-06-1) is a high-stability inorganic compound with a molecular weight of 240.79 g/mol. It typically appears as a fine black crystalline powder, known for its exceptional thermal stability, good electrical conductivity, and high catalytic activity. Our Cobalt Tetroxide meets industrial-grade standards, with high purity (minimum 99% purity) and tight control over impurities (e.g., iron (Fe) max 0.005%, nickel (Ni) max 0.003%, copper (Cu) max 0.002%). These properties make it a top choice for energy storage, catalysis, and advanced material applications.
• Excellent Thermal Stability: It retains its structure and properties at high temperatures (up to 800°C), making it ideal for high-temperature processes like battery manufacturing and catalytic reactions.
• High Catalytic Activity: Its unique crystal structure enhances catalytic performance in oxidation reactions, Fischer-Tropsch synthesis, and other industrial processes—reducing reaction times and improving product yields.
• Superior Electrical Conductivity: This property makes it a key component in lithium-ion battery cathodes, where efficient electron transfer is critical for battery performance and lifespan.
• High Purity for Consistency: With minimum 99% purity, our Cobalt Tetroxide ensures minimal variations in your processes, reducing defects in finished products like batteries or ceramics.
• Environmentally Compatible: When handled and disposed of properly, it poses minimal environmental risk, aligning with sustainable manufacturing practices.
Cobalt Tetroxide’s versatility makes it a cornerstone in several high-tech and industrial sectors:
• Energy Storage: It is a primary material for lithium-ion battery cathodes (e.g., LiCoO₂ synthesis), where its conductivity and stability improve battery capacity, charging speed, and cycle life—essential for electric vehicles and portable electronics.
• Chemical Catalysis: It acts as a catalyst in oxidation reactions (e.g., converting alcohols to aldehydes) and Fischer-Tropsch synthesis (producing liquid fuels from syngas), driving efficiency in petrochemical and specialty chemical industries.
• Ceramics and Pigments: It is used as a black pigment in ceramics and glass, imparting a rich, durable color to tiles, tableware, and decorative glass products. It also enhances the thermal stability of ceramic materials.
• Magnetic Materials: It is a precursor for manufacturing cobalt-based magnetic alloys, which are used in motors, sensors, and data storage devices due to their strong magnetic properties.
• High-Temperature Coatings: It is added to high-temperature coatings for industrial equipment, protecting surfaces from oxidation and corrosion in extreme environments (e.g., furnaces, jet engines).
Cobalt Tetroxide has the formula Co₃O₄, meaning it contains three cobalt (Co) atoms and four oxygen (O) atoms per molecule. This composition gives it its unique thermal and catalytic properties.
Its excellent electrical conductivity and thermal stability allow for efficient electron flow and prevent overheating in batteries. This translates to longer battery life, faster charging, and higher energy density—key requirements for modern energy storage.
We offer industrial-grade Cobalt Tetroxide with minimum 99% purity, as well as high-purity grades (99.5% and 99.9%) for specialized applications like high-performance batteries and advanced catalysis.
While it is stable, avoid inhaling the powder or direct skin contact. Use protective equipment (dust masks, gloves) and store it in a dry, well-ventilated area away from incompatible substances (e.g., strong acids).
• Specialized R&D Team: Our team of chemists and engineers focuses on improving Cobalt Tetroxide’s properties, ensuring our product stays ahead of industry demands for performance and sustainability.
• Strict Quality Control: Every batch undergoes rigorous testing (X-ray diffraction, elemental analysis) to verify purity and composition, guaranteeing consistent performance.
• Advanced Production Equipment: We use modern sintering and purification technologies to produce Cobalt Tetroxide with uniform particle size and minimal impurities.
• Customized Solutions: We tailor our product to your needs, whether you require specific particle sizes, impurity limits, or bulk packaging for large-scale battery production.
• Reliable Supply Chain: Our global network ensures timely delivery, even for large orders, so you never face production delays due to material shortages.
