Abstract

The optimum combination of experimental variables- temperature, time of heat treatment under nitrogen atmosphere and amount of Ni-salt has been delineated to find the maximum yield of nanophase Ni in the silica powder. The size of Ni in the silica powder is found to be 32nm and 45nm. A statistically adequate regression equation, within 95% confidence limit has been developed by carrying out a set of active experiments within the framework of design of experiment. The regression equation clearly indicates the beneficial role of the temperature and time of heat treatment.
