Roughness of the pellet of silica modified with PMPS using different protocol of synthesis. Figures show diagram and profile of pellet roughness for silicas obtained using protocol 1 (sample 2 obtained via scheme “M”; the PMPD/DMC ratio was equal to 5.5 at each stage, ACA of 121°), and protocol 2 (sample 5 obtained via scheme “M”; the PMPD/DMC ratio was equal to 5.5 at each stage, ACA of 131°). Studies were conducted on tablets compressed using the pressure 50 kgf/cm² (Table 1)
