If the volume ratio is equivalent to the area ratio, the area percentage of cobalt measured is smaller than the theoretical value in both cases. The error is slightly below 10%. With less cobalt content more important WC agglomerations are obtained. Since WC-WC boundaries are more difficult to isolate than WC-Co ones, it is possible that more separations are missing in the 906 grade than in the 45B grade. This would preferentially increase the 906 grade average grain size.
