- About Us
Manganese
Manganese (Mn) is a hard, brittle transition metal with significant importance in metallurgy and electrochemistry. Known for its role in steelmaking, oxidation-reduction reactions, and battery technologies, Manganese exhibits diverse chemical behaviors and catalytic properties.
Goodfellow’s manganese product range includes flakes, powders, foils, and rods in purities ranging from 98.7% to 99.95%. Our Manganese solutions are tailored for applications in industrial processes and scientific research. In energy storage technologies, manganese is used extensively in lithium-ion batteries as part of cathode materials that enhance capacity and stability. Additionally, manganese compounds find applications in agriculture as micronutrient fertilizers that promote healthy crop growth. Emerging areas of research include manganese-based catalysts for water splitting processes aimed at advancing hydrogen production technologies.
