摘要

It has been well accepted that polyacrylic acid (PAA) is an effective dispersant for metal diborides (such as ZrB₂) in aqueous media. However, when dispersing HfB₂ powder, the dispersing effect is reduced significantly. In this work, a second dispersant, ammonium citrate, was used to resolve this problem. It was found that a PAA-ammonium citrate binary dispersant system could effectively enhance the zeta potential, increase the PAA adsorption content, and improve the stability of HfB₂. The apparent viscosities of the suspensions were also investigated. Results showed that the PAA-ammonium citrate binary dispersant system was effective for improving the dispersion of HfB₂ particles in aqueous media.
