Ammonium Molybdate Tetrahydrate, also named Ammonium Heptamolybdate Tetrahydrate, is a core water-soluble molybdenum inorganic crystal raw material widely demanded across global industrial, agricultural and laboratory sectors.
Our AMT adopts closed-circuit crystallization & high-precision purification technology, strictly controlling heavy metal, chloride and insoluble impurity content. The finished crystal features uniform particle size, excellent water solubility and stable chemical properties, avoiding premature ammonia loss caused by air weathering.
Different from low-grade molybdate products on the market, this material supports multi-grade customization: industrial grade, analytical pure ACS grade and high-purity electronic grade. It acts as essential precursor for molybdenum catalysts, trace element fertilizer and lab testing reagent, becoming a standard molybdenum intermediate for manufacturers, labs and agricultural distributors worldwide.
1. Catalyst: Used as a catalyst in the petroleum industry to promote reactions such as oil cracking.
2. Metallurgical industry: used for the production of molybdenum, is an important raw material for the extraction of molybdenum elements.
3. Chemical raw materials: is the manufacture of ceramic glaze, pigment and other molybdenum compounds raw materials.
4. Analytical reagent:
*Used as reagent for determination of phosphate, nickel, germanium, selenium dioxide, arsenate and lead.
*Used for color layer analysis, separation and identification of components in mixtures.
*In molybdenum blue method for the determination of soil and plant phosphorus content, as well as serum inorganic phosphorus, alkaline phosphatase activity.
Strict purification removes heavy metals, chloride and residual acid; fixed ≥54% molybdenum element ensures consistent catalytic and fertilization effect, no batch fluctuation.
Fast dissolving without residue, no agglomeration during mixing; uniform crystal size improves dispersion in catalyst carrier, soil and plating liquid.
Special crystal structure slows ammonia volatilization in air, long-term storage maintains stable effective components without performance attenuation.
Industrial grade for catalyst/metallurgy, analytical grade for lab detection, electronic high-purity grade for new materials; compatible with most acid, alkali and water-based systems.
Direct raw material for molybdenum trioxide, molybdenum powder and molybdenum salt derivatives, simplifying downstream production process and reducing overall raw material cost.
