The effect of mechanochemical activation parameters—process power density and the time of treatment of a mixture of nickel hydroxocarbonate NiCO3 · 2Ni(OH)2 · nH2O and ammonium paramolybdate (NH4)6Mo7O24 · 4H2O —on the phase composition, specific surface area, and morphology of mechanically activated products at different Ni : Mo atomic ratios was studied. It was found that, at a mechanochemical activation process power density of 6.2 W/g, layered transition metal molybdates (LTM compounds) with different amounts of crystal water were the constituents of the products, whereas the products mechanically activated at a power density of 28.0 W/g contained a mixture of LTM compounds and heteropoly compounds with the Anderson structure regardless of activation time.
