Roughness of the pellet of silica modified with PMPS by single-stage modification. Figures show a diagram and profile of the pellet roughness for modified silica obtained via single-stage process using mixture with a PMPS/DMC ratio 2/1 at 200 °C a (carbon content of 6.0 wt.%, contact angle −130° [39]) and 250 °C b (carbon content of 6.6 wt.%, contact angle −129° [39]). Studies were conducted on tablets compressed using the pressure 50 kgf/cm2
