PARTICLES HAVING A SMALL SPECIFIC SURFACE AND A GREAT THICKENING EFFECT
摘要
Disclosed are particles having a relative viscosity or thickening effect ?<SUB>rel</SUB> of more than 2, measured in a liquid medium having a viscosity of 1 Pas at a temperature of 25 °C and measured at a shear gradient of 10 s<SUP>-1</SUP>. Said particles can form beds having a porosity e > 0.5 in a dry form.
