Raman spectrum of saturated aqueous solution of ammonium dimolybdate crystal was recorded, and compared with those of ammonium dimolybdate crystal, ammonium heptamolybdate crystal, saturated aqueous solution of ammonium heptamolybdate crystal and monomolybdate anion in aqueous solution respectively.

The optimal way of adding potassium is determined by analysing the potassium development and change in ammonium dimolybdate process of production and carrying out different adding potassium experiments.

This paper focused on the molybdenum powder with different morphology based on the decomposition and reduction of agglomerated and non-agglomerated ammonium dimolybdate(ADM).
