Introduction

Ammonium heptamolybdate is an important intermediate product in the process of molybdenum metallurgy. It is the main raw material for the production of molybdenum powder, molybdenum wire and molybdenum-based products. It is also used in chemical and petroleum catalysts, flame retardants, dyes, pigments and trace element fertilizers. field. With the rapid development of molybdenum high-tech products, ammonium heptamolybdate has become an indispensable material in high-tech fields such as superconductivity, cermet, laser, computer, polymer synthesis and testing.

Chemical properties

Use

●  It is used as a reagent for the determination of phosphate, alkaloid, arsenate and lead, as a reagent for chromatographic analysis, and for the extraction of metal molybdenum, the photography industry and the manufacture of pottery glaze.
The overview, preparation process and use of ammonium heptamolybdate are edited by Shi Yan.

●  It is used in petroleum cobalt, molybdenum catalyst, pigment chemical industry and micro-fertilizer. There are also a few powder metallurgy enterprises that use ammonium heptamolybdate as raw material.

●  For the preparation of catalysts, metal molybdenum, pigments, metal surface treatment agents, corrosion inhibitors, trace element fertilizers, etc.

●  For the preparation of catalysts, metal molybdenum, pigments, metal surface treatment, corrosion inhibitors, trace element fertilizers, etc.

Production method

●  Stir the pulverized industrial molybdenum trioxide, water and ammonia water to dissolve them. Filter and wash the insolubles with ammonia water. Ammonium sulfide solution was added to the filtrate, heated and filtered. Evaporate and concentrate to a relative density of 141, add ammonia water, and keep stirring until there is a strong smell of ammonia. Cooling and suction filtration to obtain pure ammonium molybdate.
