Precipitation method An aqueous solution of magnesium salt (e.g., MgCl2) is mixed with an aqueous solution of sodium hydroxide or calcium hydroxide to produce a magnesium hydroxide precipitate. Filter and wash the precipitate to remove impurities. Dry the precipitation to obtain high specific surface area magnesium hydroxide powder. Thermal decomposition method Magnesium carbonate (MgCO3) or […]

INTRODUCTION EVA (ethylene vinyl acetate copolymer) is a flexible thermoplastic elastomer widely used in photovoltaic cells and electrical applications due to its excellent transparency, flexibility and insulating properties. Magnesium hydroxide (Mg(OH)2) is a flame retardant and filler that improves the thermal stability and mechanical properties of composites. The aim of this study is to characterize

Principle The brine ammonia reverse precipitation method utilizes the chemical reaction between brine (containing magnesium chloride) and ammonia to generate magnesium hydroxide precipitation, and by controlling the reaction conditions, the product of magnesium hydroxide with hexagonal flake shape is obtained. Process flow Pre-treatment of raw materials: brine is clarified, concentrated and decontaminated to obtain qualified

Preparation of Magnesium Hydroxide Magnesium hydroxide (Mg(OH)2) is an inorganic compound with a variety of industrial and medical applications. Common methods of preparation include: Precipitation: a solution of magnesium salt is reacted with a base (e.g., sodium hydroxide or sodium carbonate). Electrolysis: seawater or salt lake water is electrolyzed in an electrolyzer. Pyrolysis: mixing a
