Abstract
The present invention provide metallic nickel powder in which the occurrence of delaminatoin can be prevented by providing superior sintering propreties in production processes for multilayer ceramic capacitors and by providind superior dispersion characteristics in the forming of conductive pastes. By being brought into contact with nickel chloride gas and a reducing gas at a temperature in the range of the reduction reaction, metallic nickel power is node gas and a reducing gas at a produced in which the oxigen content is 0.1 to 2.0% by weight and there is not absortion peak at wavelengths ranging from 3600 to 3700 cm−1 in infrared spectroscopy.
