Potassium Molybdate (CAS 13446-49-6) is a water-soluble molybdenum salt supplied in Technical Grade as a white, deliquescent microcrystalline powder, and it serves as a molybdenum source for crop nutrition and as a corrosion inhibitor in closed-circuit cooling systems and antifreeze formulations. It appears as a white crystalline powder with excellent solubility in aqueous systems. In the agricultural sector, it serves as a high-efficiency micronutrient fertilizer , essential for nitrogen fixation in legumes. It is preferred for foliar application due to its rapid uptake and high potassium content. Its oxidizing properties help form a passive protective film on ferrous metal surfaces.
