Abstract Scope |
There is limited information in the literature on the correlation between particle size and pore size, and the role of processing on this relationship. A series of samples were produced from flocculated and dispersed suspensions prepared from commercial powders. Monomodal and bimodal distributions were also tested. These samples were heat treated to improve mechanical integrity prior to the measurement of pore size distributions using Hg-porosimetry. The results demonstrated that the presence of hard agglomerates could not be determined from porosimetry data and the contribution of the level of dispersion only created a marginal shift in the pore size distribution. In bimodal distributions, mixing was critical and if the small particles filled the spaces between the large particles, the pore size distribution was similar to that obtained from the fine powder by itself. |
