ABSTRACT

We characterized the growth behavior of nano NiO crystals synthesized by heat-treatment in air at the elevated temperatures using nickel nitrate (Ni(NO3)2·6H2O). The crystals had the octahedral shape and the length of 200~500 nm. The truncation was observed when the NiO powder was heated up to 900℃for 2 hours. but not be seen at under 600℃It was observed that nano NiO crystals synthesized at 900℃made up the networks, the coalescence of the nano crystals through the neck formation between the crystals appeared as the first stage in the sintering mechanism.
