The conversion may be effected by NO- 3  ions or halogen oxy-acid ions at above room temperature. The pH may be stabilized by adding, below the surface, a solution of NaHCO 3 , Na 2 CO 3  or NH 3  or by adding urea to the solution before or during precipitation. In an example, a Co/Fe oxide powder with an X-ray pattern analogous to Fe 3 O 4  is made by precipitation from a urea-containing solution of Co(NO 3 ) 2 6H 2 O and FeCl 2 . Magnetic tapes are made by incorporating the powder in a polyurethane binder on a polyester substrate.
