Abstract

Ultrafine Ni-Zn ferrites, $Ni_xZn_{1-x}Fe_20_4$, have been prepared by the thermal decomposition/combustion of novel solid solution precursors of the type, $(N_2H_5)_3Ni_xZn_{1-x}Fe_2(N_2H_3COO)_9.3H_20$ where x = 0.2 to 0.8. The novelty of the precursors being their low temperature, exothermic, gas producing self-sustained decomposition. Fine particle nature of the ferrites has been indicated by X-ray powder diffraction, transmission electron microscopy and surface area measurements. Fine particle Ni-Zn ferrites sinter at $1000^0C$, 24 h to achieve almost 99% theoretical density.
