Abstract

Ultrafine and nearly spherical ferrites such as NiFe₂O₄, ZnFe₂O₄, Ni_xZn_1−xFe₂O₄, Mn_0.5Zn_0.5Fe₂O₄, and CoFe₂O₄ were prepared under mild hydrothermal conditions by precipitating from metal nitrates with aqueous ammonia. These hydrothermal ferrite powders were shown to sinter to almost theoretical density at 1000°C without any sintering aids.
