Applications of 7439-98-7
| Industry | Application | Process |
|---|---|---|
| Metallurgy | Alloy additive (e.g., for high-speed steel, stainless steel, tool steel) | Added as ferromolybdenum or metallic molybdenum during melting to enhance strength, hardness, heat resistance, and corrosion resistance |
| Petrochemicals | Hydrodesulfurization (HDS) catalyst | Supported on alumina or similar carriers as molybdates or molybdenum sulfide for hydrotreating petroleum fractions |
| Electronics & Electrical | Semiconductor interconnect material, thin-film transistor electrode | Molybdenum thin films deposited via physical vapor deposition (PVD) or chemical vapor deposition (CVD) |
| Chemicals | Catalyst (e.g., for acrolein oxidation to acrylic acid) | Mixed metal oxides containing molybdenum, bismuth, and iron used as heterogeneous catalysts |
| Aerospace | High-temperature structural material (e.g., jet engine components) | Molybdenum-based high-temperature alloys produced by powder metallurgy or vacuum melting |
| Glass Manufacturing | Stirrers and electrodes for molten glass | Directly machined into shape and used in high-temperature glass melting furnaces, leveraging molybdenum’s high melting point and resistance to molten glass erosion |
| Agriculture | Trace element fertilizer | Sodium molybdate or ammonium molybdate applied to molybdenum-deficient soils to support nitrogen fixation in leguminous crops |
| Pigments & Coatings | Molybdenum orange and molybdenum red pigments | Inorganic colored pigments prepared by co-precipitation of lead molybdate and lead chromate |
