Product Introduction

Ammonium molybdate is also known as secondary ammonium molybdate. Molybdate of ammonium. Chemical formula (NH4)2MoO4, molecular weight 196.01, colorless or light yellow-green monoclinic prismatic crystals, relative density 2.27625, weathering in air, loss of ammonia. Relative density 2.27625. Weathers in air and loses ammonia. Soluble in water (but decompose in hot water, acid), dilute ammonium chloride solution, insoluble in ethanol, ammonia, acetone. Heated to 400 ℃ decomposed into molybdenum trioxide and ammonia. Reaction with nitric acid Chemicalbook generates yellow molybdic acid monohydrate. With the increase of system acidity, generate polymolybdic acid. React with phosphoric acid, silicic acid, vanadic acid and arsenic acid to form a series of different ratios of heteropolyacids. Method: Add molybdenum trioxide to ammonia, add ammonium sulfide solution to the filtrate and crystallize. Uses: Used as a reagent for the determination of phosphate, alkaloid, arsenate and lead, as a reagent for chromatographic analysis, as well as for the refining of molybdenum metal, the manufacture of photographic industry and pottery glaze.

Main Uses

Ammonium molybdate is mainly used for smelting molybdenum iron and the production of molybdenum trioxide, molybdenum metal powder; as tungsten and molybdenum alloy, molybdenum wire as raw materials; used in geological exploration of phosphorus ores; used as a catalyst for the chemical industry; a small amount of molybdenum fertilizers used for agricultural purposes; a very small amount of pharmaceuticals; for a variety of enzymes, the molybdenum deficiency will lead to dental caries, kidney stones, Crohn's disease, osteoarthritis, esophageal cancer and other diseases.

① used as pigments, color precipitates and fabric flame retardant fire retardant, is the main raw material for the preparation of molybdenum products, is also an important agricultural fertilizer

② Used in powder metallurgy, high purity molybdenum trioxide and other molybdenum chemicals raw materials.

③Petrochemical industry as a catalyst, metallurgical industry for the production of molybdenum powder, molybdenum strips, molybdenum wire, molybdenum billet, molybdenum flake, etc., can also be used as a trace element fertilizer, is a commonly used in agriculture, a water-soluble molybdenum fertilizer. For seed treatment and extra-root fertilizer, soaking seeds can be 0.05% ~ 0.1% ammonium molybdate dissolved Chemicalbook liquid, soaked for about 12h. Seed mixing with ammonium molybdate 1g per 500g of seed, foliar spraying with 0.05% to 0.1% ammonium molybdate solution. When preparing ammonium molybdate solution, first dissolve it with a small amount of hot water, and then dilute it to the desired concentration.

④It is an important reagent for the determination of phosphorus and the best material for the production of acrylonitrile catalysts

⑤ It is used in the production of molybdenum wire and other molybdenum compounds, and is also used in photography, ceramics, pigments, and catalysts.

⑥ used as analytical reagent, also used in the preparation of pottery glaze
