摘要：

Uniform spherical colloidal particles of mixed nickel basic and cadmium phosphates were prepared by aging at 80-degrees-C solutions containing the corresponding metal sulfate salts and phosphoric acid in the presence of urea and sodium dodecyl sulfate. The molar ratios of metal ions in the precipitated solids depended on the initial ratio [Cd2+]/[Ni2+] in solution and, for a given initial solution concentration, on the aging time, which also affected the particle size. The calcination of initially amorphous powders produced different crystalline products that varied with the original composition of the solids.
