摘要：

Crystalline powder of zinc ferrite was synthesized from the mixed solution of FeCl2 and ZnCl2 by adding hydrazine monohydrate solution and aging near room temperature from 30 to 60 degrees C. The temperature condition for this synthesis was the same as that using aqueous ammonia reported previously. However, it was necessary to keep the concentration of metal chlorides below 1 x 10(-1) mol dm(-3) to obtain zinc ferrite, because hydrazine complexes with metal chlorides in solutions with high concentration. Zinc ferrite was also formed starting with FeCl3 solution, probably because hydrazine I educes Fe3+ partly to Fe2+.
