摘要：

The cobalt modification of “pure” γ-Fe2O3 acicular particles by the so-called “epitaxial process” has been applied to γ-Fe2O3 particles, derived from oxalic precursors. Six elaboration parameters have been taken into account for the slurry heat treatment: cobalt content, pH, time, temperature, gas flowing into the solution and surface activation. A thermomagnetic study including in situ annealing treatments and magnetic measurements at various temperatures in the range 20–380°C has been carried cut. The results are compared with those of commercial surface cobalt modified pigments. © 1990 IEEE
