High-Purity Electrolytic Manganese Flake

Product Specifications

Technical details and manufacturing context for High-Purity Electrolytic Manganese Flake

Definition

High-purity electrolytic manganese flake is a critical raw material in ferrous and non-ferrous metallurgy, produced through the electrolytic reduction of manganese sulfate solutions. This material serves as a vital alloying agent to enhance the strength, hardness, and wear resistance of steel and aluminum alloys. Its high purity ensures minimal introduction of unwanted impurities during the alloying process, making it essential for producing high-performance specialty steels and superalloys. The flake form provides excellent surface area-to-volume ratio, facilitating rapid dissolution and uniform distribution within molten metal baths.

Typical specifications for this material include a manganese content of 99.7–99.9% (minimum), with strict limits on impurities such as carbon (≤0.01%), sulfur (≤0.03%), phosphorus (≤0.001%), iron (≤0.02%), silicon (≤0.002%), selenium (≤0.001%), and moisture (≤0.05%). The flake thickness typically ranges from 1 to 3 mm, with a bulk density of 2.5–3.5 g/cm³. Particle size can be customized from 5 to 50 mm. The melting point is approximately 1244–1246°C. These values are reference ranges and should be verified with the supplier for specific applications.

This product is listed in the CNFX directory as a material for industrial procurement. It is not manufactured or sold by CNFX. Always confirm model-specific values and applicable standards (e.g., GB/T 2774) with the legal manufacturer or supplier before use.

Working Principle

The production of high-purity electrolytic manganese flake involves the electrolytic deposition of metallic manganese from an aqueous manganese sulfate solution onto cathode plates. The process uses sulfuric acid and deionized water as part of the electrolyte system. During electrolysis, manganese ions are reduced and deposited as a solid layer on the cathode. After deposition, the manganese is mechanically stripped from the cathode and processed into flake form. The flake geometry offers a high surface area-to-volume ratio, which promotes rapid dissolution and uniform distribution when added to molten metal baths during alloying.
