Abstract

Fine particle nickel-zinc ferrites, $Ni_xZn_{1-x}Fe_20_4$ where x = 0.2-0.8 have been prepared, both by the thermal decomposition of the precursor, $(N_2H_5)_3Ni_xZn_{1-x}Fe_2(N_2H_3COO)_9.3H_20$ and combustion of redox mixtures containing nickel nitrate, zinc nitrate, iron(III) nitrate, and oxalic acid dihydrazide (ODH) in the required mole ratio. Both the processes yield submicrometer size (60-90 nm), large surface area $(85-108 m^2/g)$, sinteractive powders which when heated at $1050^oC, 3 hr$ achieve >98% of the theoretical density.
