Interfacial phenomena of magnesium hydroxide micro phases

The magnesium hydroxide aqueous suspensions were prepared over a wide range of different types of dispersants with different dosages percentage. The effect of dispersant types and dispersant dosages on the rheological behavior and stability of magnesium hydroxide aqueous suspensions have been investigated by means of viscosity, sedimentation measurements, flowability, Total organic carbon (TOC) and zeta potential. The results showed that considering the four types of dispersants, Calcium lignosulfonate (Ca-lig) enhance the viscosity and flowability of the slurry the most. Also it decreases the pH of slurry. The study gives insights on important application process optimization.
