Abstract

In this study, the dehydration and hydration reactivity of citrate-added magnesium hydroxides was studied. Sodium citrate added magnesium hydroxide dehydrated efficiently at around 350°C, and this temperature were lower than the dehydration temperature of the authentic magnesium hydroxide. In cyclic dehydration/hydration reaction test, the dehydration temperature at the second cycle was 40°C lower than that at the first cycle for C6H5Na3O7/Mg(OH)2. Regarding the hydration reaction, it was generally improved compared with the authentic magnesium hydroxide.
