Abstract
The influence of Co additions on the sintering of nickel oxide was studied. On the basis of the density, specific surface area and Me3+ ion concentration changes, in the Co y Ni1−y O samples, having 0, 1, 5 and 10 cation % of Co, a positive effect of Co ions on the densification was assumed, during sintering at 500 to 900° C in an argon atmosphere. Using special heat-treatment, the differences in specific surface area of the investigated powders were eliminated. The differences in green densities were excluded as well and from the results, it was possible to show that dissolved Co ions enhance nickel oxide densification process.
