Properties and Uses |
|
Ammonium dimolybdate [£¨NH4£©2Mo2O7], soluble in water and alkali, suitable to produce molybdenum trioxide and molybdenum powder and manufacture molybdenum plates, molybdenum wires and molybdenum elements, also widely used in the production of catalysts for hydrogenation and desulfurization of petroleum refining, fertilizer catalysts, etc. Ammonium tetramolybdate [£¨NH4£©2Mo4O13¡¤2H2O],[£¨NH4£©2Mo4O13], slightly soluble in water, soluble in alkali and ammonia, used in the production of catalysts for hydrogenation and desulfurization of petroleum refining, fertilizer catalysts and the electronic industry. Ammonium hepta-molybdate [£¨NH4£©6MO7O24.4H2O ], white or slightly green crystalline powder, not soluble in alcohol, the solubility in the water under the normal water can reach over 40g., used as an important reagent for testing phosphorus, as the best material to produce acrylonitrile catalyst and in the production of microelement fertilizers and molybdenum. |
