Magnesium hydroxide precipitates, while calcium hydroxide remains in solution. Magnesium hydroxide is filtered off and on heating readily forms the pure the oxide. Conversion to magnesium chloride is achieved by heating the oxide, mixed with carbon, in a stream of chlorine at a high temperature in an electric furnace (Figure 1).
R.C. Ropp, in Encyclopedia of the Alkaline Earth Compounds, 2013. Magnesium Hydroxide. Magnesium hydroxide has the chemical formula Mg(OH) 2 and the molecular weight of 58.3197 g/mol. Its CAS number is 1309-42-8 and its density is 2.345 g/cm 3.It decomposes when heated to 360 °C and forms the oxide, MgO.
