Abstract:
A method for producing an ammonium octamolybdate isomer comprising:providing a supply of ammonium dimolybdate, a supply of molybdenum trioxide, and a supply of water;selecting one of said supply of ammonium dimolybdate and said supply of molybdenum trioxide for use as a first reagent and another of said supply of ammonium dimolybdate and said supply of molybdenum trioxide for use as a second reagent;combining said first reagent with said water to produce an intermediate product;adding said second reagent to said intermediate product in order to generate an aqueous chemical mixture, said adding of said second reagent to said intermediate product comprising delivering said second reagent to said intermediate product in a gradual, non-instantaneous manner in order to avoid delivery of said second reagent to said intermediate product all at once; andheating said aqueous chemical mixture to produce a reaction product comprising said ammonium octamolybdate isomer therein, said ammonium octamolybdate isomer having Raman spectra peaks at wavelength values of about 953-955 cm.sup.-1, about 946-948 cm.sup.-1, and about 796-798 cm.sup.-1.
