Application of ammonium molybdate
Used as a catalyst in the petroleum industry and used in the metallurgical industry to produce molybdenum, as raw material for ceramic glazes, pigments and other molybdenum compounds. 2, this product is an additive flame retardant, with dual functions of flame retardant and smoke suppression. The compound with other flame retardants can reduce the cost, improve the flame retardancy and reduce the amount of smoke. Molybdenum trioxide also has the dual effects of flame retardancy and smoke suppression, and it shows certain synergistic effect with aluminum hydroxide trihydrate and antimony oxide. Used as analytical reagent for the determination of phosphate, phosphite, arsenate and penicillins by photometric or thin layer chromatography. Also used in photography industry, pottery glaze. 4, used for the preparation of iron and steel bonding oil removal, rust removal, phosphating, passivation four-in-one surface treatment agent. It is also used as raw material of catalyst for dehydrogenation and desulfurization of petroleum. Can also be used for metal molybdenum, pigments, agricultural trace element fertilizer molybdenum fertilizer. Ammonium molybdate is used as black passivation solution for zinc plating, as stabilizer for electroless nickel plating, and as oxidant for iron and steel phosphating solution, etc. [2] ammonium molybdate is mainly used for smelting ferromolybdenum and preparing molybdenum trioxide, metal molybdenum powder is used as raw material for tungsten-molybdenum alloy and molybdenum wire, followed by catalyst for chemical industry, a small amount for agricultural molybdenum fertilizer. Rarely used in medicine, as a component of a variety of enzymes, molybdenum deficiency can lead to caries, kidney stones, Keshan disease, Kashin-Beck disease, esophageal cancer and other diseases. It is mainly used in patients with long-term dependence on intravenous hypernutrition.
