Magnesium Hydroxide, Mg(OH)2, also known as milk of magnesium, is the active ingredient in many over-the-counter stomach ant-acid. Though a strong base, it has limited solubility, which tempers its alkalinity and makes it safe for ingestion.

Magnesium hydroxide is an insoluble gelatinous material. It can react slowly with silica gel to form a hydrated magnesium silicate which does not have any binding properties. The calcium sulphoaluminate formed by the reaction of CaSO4.2H2O and 3CaO.Al2O3 due to the action of magnesium sulphate is further decomposed to gypsum, hydrated alumina, and magnesium hydroxide by magnesium sulphate for example. The SiO2 is also made available for ASR.

Magnesium hydroxide, Mg(OH)2, can be produced either from precipitation or electrochemical processes. The precipitation method can be carried out by adding NaOH as an alkaline agent, with the possible formation of other precipitates. Unfortunately, however, this method also generates large amounts of sludge. In contrast, the electrolysis process may result in a higher recovery rate of magnesium hydroxide, with fewer impurities [44].
