Abstract

The dispersion of highly concentrated Zirconium diboride ( ZrB 2 ) suspension in aqueous media was investigated in terms of zeta potential and rheological measurements, with a salt of polyacrylate polymer ( SD ‐07) as dispersant. The adsorption behavior of SD ‐07 on ZrB 2 particle surface was also studied. Results showed that acid cleaning improved the fluidity of aqueous ZrB 2 slurry. Concentrated (up to 50 vol%) and well‐stabilized suspension was obtained in the alkaline pH region, with 0.60 mg/m 2 SD ‐07. On this basis, 50 vol% ZrB 2 gelcasting slurry was prepared. The linear shrinkage and flexural strength of as‐casted green body were (3.42 ± 0.13)% and (9.4 ± 0.3) MPa, respectively.
