Applications
Ammonium molybdate is an important inorganic molybdenum salt with wide industrial and laboratory uses. It is commonly used as raw material for preparing molybdenum oxide, molybdenum metal powder and various molybdate products. In chemical analysis, it acts as classic analytical reagent for phosphorus, silicon, arsenic and heavy metal detection, widely applied in water quality testing, soil analysis and chemical titration.
In agricultural field, it serves as high-efficiency molybdenum fertilizer trace element additive, promoting nitrogen fixation and growth of leguminous crops. In metallurgy industry, it is used as alloy additive to improve steel hardness and corrosion resistance. It also works as catalyst for petrochemical and organic synthesis, as well as raw material for ceramic glazes, pigment additives and electronic component materials.
Safety Information
This compound has slight irritation to skin, eyes and respiratory tract. Direct skin contact may cause dryness and mild allergic discomfort; long-term dust exposure may induce dermatitis. Eye contact will lead to congestion, stinging and foreign body sensation, requiring immediate rinsing with plenty of clean water. Inhalation of dust may irritate nasal and throat mucosa, causing cough and respiratory discomfort. Accidental ingestion may trigger mild gastrointestinal reactions such as nausea and stomach upset.
It has certain toxicity to aquatic organisms and should not be directly discharged into water bodies and soil. During handling, wear protective gloves, dust mask and safety goggles, operate in well-ventilated environment. Keep away from strong acids, oxidants and high-temperature heat sources. Store sealed and moisture-proof. Waste residues and packaging shall be disposed in accordance with inorganic chemical waste regulations to prevent environmental pollution and health risks.
