Description

Huebnerite is a naturally occurring mineral and a primary source of manganese, identified by the CAS number 15501-92-5. This compound is valued for its high manganese content and specific crystalline structure, making it a critical raw material in several industrial processes. It is primarily sought by the metallurgical, chemical manufacturing, and specialty ceramics industries for alloy production and as a precursor in inorganic synthesis.

Application

• As a key manganese ore in the production of ferromanganese and silicomanganese alloys for the steel industry.
• As a raw material for the synthesis of various manganese chemicals and compounds, such as manganese sulfate and potassium permanganate.
• In the manufacturing of welding rod coatings and fluxes.
• As a colorant and glaze component in the ceramics and glass industries.
• In the production of dry-cell batteries as a source of manganese dioxide.
• For research and development in material science, particularly in studying tungstate and manganous mineral structures.

Quality Control

Our Huebnerite is sourced and processed to meet stringent quality parameters for industrial use. Each batch undergoes rigorous testing to ensure consistency in manganese content, purity, and particle size distribution. Certificates of Analysis (COA) detailing assay and impurity profiles are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at ambient temperature. Keep away from incompatible materials such as strong acids. The material is not typically hygroscopic but should be protected from prolonged exposure to moisture to prevent caking.
