A ferroalloy composed of molybdenum and iron, generally containing 50 to 60% molybdenum, used as an alloy additive in steelmaking. Molybdenum is an alloy of molybdenum and iron. Its main use is as an additive to molybdenum in steelmaking. The addition of molybdenum to steel can make the steel have a uniform fine grain structure and improve the hardenability of steel, which is conducive to eliminating tempering brittleness. In high-speed steel, molybdenum can replace part of tungsten. Molybdenum is widely used in the production of stainless steel, heat-resistant steel, acid-resistant steel and ...

It usually appears granular, with a slightly yellow appearance, a maximum particle size of 5mm, a specific gravity of 4.692g/cm3, and begins to sublimate above 600 C. It is stable in air, slightly soluble in water, insoluble in general acids, soluble in ammonia, hydrofluoric acid and concentrated sulfuric acid. It is used as a raw material for the preparation of ferromolybdenum and molybdenum compounds, and can also be directly added to molybdenum alloys as an additive of molybdenum to improve the properties of alloys.

Sulfur dioxide: It is used as an organic solvent and refrigerant, and for refining various lubricating oils. It is primarily used in the production of sulfur trioxide, sulfuric acid, sulfites, and thiosulfates, and also serves as a fumigant, preservative, disinfectant, reducing agent, etc.Sodium sulfite: Used for the microanalysis and determination of tellurium and niobium, as well as the preparation of developer solutions, and also serves as a reducing agent; used as a stabilizer for artificial fibers, a bleaching agent for fabrics, a photographic developer, a deoxidizer for dyeing and bleach...
