Spinel Nico2o4

The high-dispersed powder−precursors of nickel−cobalt spinel (NiCo2O4) was synthesized by the method of coprecipitation of the nickel and cobalt hydroxides with followed by drying (150 °C) and ultrasonic (US) treatment of the precipitate. The influence of US−treatment on the texture characteristics of the precursors and NiCo2O4 powders was established. The possibility of obtaining nanodispersed (crystallite size < 20 nm), mesoporous powders (pore size 3 − 15 nm) of nickel−cobalt spinel at a temperature of 700 °C is shown. The change in the specific electrical conductivity of sintered NiCo2O4 samples in the temperature range of 100 – 800 °C was studied, the value of σ can vary from 0.1 to 7.0 Sm/cm.
