Table 1 Diameter of a particle, and the hydrodynamic diameter and zeta potential of a particle dispersed in distilled water before and after thermal treatment.
Diameter (nm) | Hydrodynamic diameter (nm) | Zeta potential (mV) | |
|---|---|---|---|
Before thermal treatment | (5.15 ± 0.62) × 102 | (1.30 ± 0.09) × 103 | − 38.8 ± 0.7 |
After thermal treatment at 600 °C for 1 h | (4.44 ± 0.63) × 102 | (0.86 ± 0.02) × 103 | − 35.4 ± 1.0 |
