Molybdenum foil used in the chemical industry is characterized by excellent corrosion resistance and chemical stability, widely applied in acid-resistant equipment, reaction vessels, and catalyst supports. Typically with 99-99.9% purity, produced via powder metallurgy or rolling, it has a density of 10.28 g/cm³, tensile strength of 500-700 MPa, and hardness of 150-200 HV, offering good wear resistance for long-term use. Its core advantage lies in chemical properties: at room temperature, it resists dilute acids (e.g., hydrochloric, dilute sulfuric, phosphoric), alkalis (e.g., sodium hydroxide), and water, with corrosion resistance surpassing iron and nearing stainless steel. It tolerates hydrofluoric acid well but is sensitive to oxidizing acids (e.g., concentrated nitric acid, hot concentrated sulfuric acid), corroding easily, requiring avoidance. At high temperatures (above 600°C), it forms volatile MoO₃ in oxidizing environments, degrading the surface, necessitating vacuum or inert gas (e.g., nitrogen, argon) protection. Mechanically, it has moderate ductility (elongation 10-20%) for forming and good creep resistance at 1000°C, suitable for high-temperature chemical equipment. Surfaces are often acid-washed or polished to enhance corrosion resistance. Applications include chemical reactors, pipeline linings, and electrodes, requiring resistance to acids, alkalis, and mechanical stress. Advantages include high corrosion resistance and stability; disadvantages are high-temperature oxidation sensitivity and cost. Quality control involves chemical analysis and corrosion testing to meet chemical industry standards.
