Preparation methods
PreparationAluminum sulfate, magnesium sulfate, and sodium carbonate are prepared under specific conditions through a coprecipitation displacement reaction in a certain concentration and molar ratio. Sodium carbonate hydrolyzes to release hydroxide ions, which then undergo a coprecipitation displacement reaction with magnesium and aluminum salts to form Almagate. Under electric stirring in a 90°C water bath, a mixture of appropriate proportions of aluminum sulfate and magnesium sulfate, along with a certain amount of anhydrous sodium carbonate solution, is slowly added dropwise to a suitable amount of water over approximately 1 hour, followed by a further 20 minutes of reaction. After aging, the product is filtered, thoroughly washed with distilled water, and dried at 100°C to obtain Almagate.
