- •
Zeta potential ζ, isoelectric point IEP and agglomeration of Li0.5La0.5TiO3 colloidal suspensions were studied.
- •
Zeta potential of Li0.5La0.5TiO3 varied from positive to negative with increasing pH from 2 to 8.
- •
Li0.5La0.5TiO3 suspensions reached the isoelectric point at pH range of 3–5.
- •
Li0.5La0.5TiO3 colloidal suspensions were stable in the pH range of 7.0–8.0.
- •
Li0.5La0.5TiO3 nanoparticles aggregated rapidly at ionic strengths >1 mmol/dm3.
