The dispersion and rheology of aqueous Z r B 2 nanosuspensions were investigated by zeta potential measurements, particle size measurements, sedimentation tests, and rheology measurements, with poly (acrylic acid) ( PAA ) as dispersant. Results showed that the dispersion and rheology of nanosized Z r B 2 suspensions in aqueous media were dependent on p H value, PAA concentration, solid loading, and ball milling time. Concentrated (up to 30 vol% solid loading) and well‐stabilized aqueous Z r B 2 nanosuspension with low viscosity (0.485 Pa s at 60/s) was prepared at p H 10, with 1.0 wt% PAA .
