| Abstract: | Magnesium hydroxide flame retardant was obtained from the deposition reaction between cal- cined and digested dolomite and brine. The prepared magnesium hydroxide was characterized by X-ray diffraction （XRD）, thermogravimetric differential thermal analysis （TG-DTA）, and scanning electron microscopy （SEM）. The impact of the reaction temperature, brine concentration, feed rate and aging time on the purity of Mg （OH） 2 was investigated. The results showed that the flaky Mg （OH） 2 products could be obtained when the reaction temperature was 60 ℃, brine concentration was 1.0 mol / L, and feed rate was 3 mL/min. The obtained flaky magnesium hydroxide had a purity of more than 98 %, and was suitable for being used as flame retardant additive. |
