Fig. 4 represents the sedimentation analysis of BSO slurry with varying amount of dispersant. Here, the ratio of sediment height to initial height (H/H0) is plotted against time (min). It is clear from the figure that, a slurry with 1.0 wt.% fish oil shows a slow settling rate compared to all other dispersant concentrations. This result is evidently corroborating with the viscosity analysis. Hence, from these two results, one can conclude that the optimum level of fish oil required for the preparation of highly dispersed homogeneous slurry is 1.0 wt.% with respect to BSO ceramic powder.
