Surface potential of hematite particles in high concentration electrolytes: Electroacoustic measurements and suspension stability

- Zeta potential of hematite particles has been measured by electroacoustic method.
- Various 1:1 electrolytes from 1 mM to 10 M have been used.
- Neutralization of surface has been observed above 0.1 M.
- Stability of suspensions using DLVO theory has been experimentally checked.
