Summary】:

Ammonium molybdate is a kind of salt which is composed of cationic ammonium and various kinds of molybdenum anions. It is one of the most important molybdate and also one of the most important molybdenum compounds, and has wide application fields. The varieties of ammonium molybdate produced today tend to be diversified. The solubility, particle size, thermal decomposition temperature and crystal shape of ammonium molybdate are different.
There are two varieties: ammonium molybdate ammonium molybdate, chemical formula (NH4) 2 Mo2O7 three; ammonium molybdate, chemical formula (NH4) 2Mo3O10; four ammonium molybdate, chemical formula (NH4) 2Mo4O13 - 2H2O; seven ammonium molybdate, chemical formula (NH4) 6Mo7O24 4H2O, also known as ammonium paramolybdate. It also has a variety of crystalline water forms. Eight ammonium molybdate, chemical formula (NH4) 4 Mo8O24.
At present, ammonium molybdate was used for the production of pure molybdenum trioxide, molybdenum powder. It is a precursor to the production of a variety of molybdenum processing material (such as light source, electronic materials, nuclear materials, aerospace materials, etc.) can be used as catalyst production (such as oil refining, reforming, coal liquefaction, diamond synthesis, etc.) the production of molybdenum carbide and molybdenum nitride precursor, smoke suppression agent, ceramic glaze, pigment, soap and molybdenum fertilizer.
This product is mainly used for catalyst, fire retardant oil industrial artificial wool industry; reagents can also be used as photographic, powder metallurgy, ceramics, enamel, paint, pharmaceutical raw materials, determination of phosphate, arsenate and lead etc..
