Semilog coordinates are widely applied in presenting characteristics of porous systems. Here, two types of diagrams were considered - cumulative diagrams and diagrams of first derivatives of cumulative curves. While deriving, two kinds of increments (dx and dlogx), concerning the independent variable, were taken into account. A comparative analysis of mentioned diagrams was performed. Based on the analysis, it was concluded that semilog coordinates are particularly suitable for presenting characteristics of porous systems, despite all noticeable disadvantages. As illustrative examples; pore volume and pore area of a catalyst and apparent density of a ceramic compact were used.
