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.

The influence of magnesium acetate and the reactivity of the two types of caustic calcined magnesia were studied by thermogravimetric analysis, differential scanning calorimetry, mass spectrometry, particle size detection and pH. Also, both citric acid and acetic acid test were done to measure the reactivity of magnesium oxide powder. The results indicate that the hydration rate of both oxides in magnesium acetate system are vigorously exothermic compared to the water system. The study shows mechanistically that magnesium acetate enhanced the degree of hydration of magnesium oxide due to the presence of acetate ions and Mg2+ ions when it compared to water. Mathematical models confirm the findings.
