Abstract
Spinel-type solid solutions in the whole range of compositions between ZnGa 2O 4 and ZnFe 2O 4 were directly precipitated as nanoparticles by dropping the starting mixed solutions of zinc sulfate, gallium sulfate, and either divalent iron chloride or trivalent iron nitrate into aqueous ammonia at 90°C. Direct precipitation of nanosized spinel-type Zn(Ga,Fe)O 4 solid solutions was also achieved by aging the mixed solutions in the presence of either urea or hexamethylenetetramine at 90°C except for one case (i.e., aging the solutions using trivalent iron salt in the presence of urea). With increased iron content in the spinel-type solid solution precipitates, their crystallite size decreased when trivalent iron salt was used, but increased when divalent iron salt was used. Change of lattice parameter a 0 of the spinel-type solid solutions was confirmed to follow the Vegard's Law.
