Rheological behavior of pyrophyllite − water slurry in the presence of anionic, cationic, and nonionic surfactants / Himanshu Desai in Industrial & engineering chemistry research, Vol. 49 N° 11 (Juin 2010)

The slurry is non-Newtonian and thixotropic in nature, and the hysteresis area increases with increasing clay concentration. In the presence of acidic pH, surface potential is low and viscosity is high; the opposite is true for alkaline pH. The rheological behavior is different in the presence of three surfactants. The viscosity highly depends on the types of surfactant adsorbed on the clay surface and surface potential after the adsorption. The d(001) lattice spacing of the pyrophyllite clay does not change after the adsorption of surfactants, indicating that the surfactants are not adsorbing inside the clay spacing.
