Ultrafine and nearly spherical particles of Mn0.8Zn0.2Fe2O4 were prepared under mild hydrothermal conditions by precipitating from metal nitrates. Mössbauer spectrosopic and magnetization measurements revealed the superparamagnetic nature of these particles having crystallite sizes around 18 nm. These ferrites were found to sinter to almost theoretical density with little or no intergranular porosity.
