Introduction
Chinese synonyms for Magnesium hydroxide are caustic Magnesium stone, light burned magnesia and so on. Suspension liquid of Magnesium hydroxide is called Magnesium hydroxide emulsion, which is called for short as "magnesia and its English name is the Magnesium hydroxide. It’s colorless six square column crystal magnesium hydroxide or white powder, which is poorly soluble in water and alcohol but soluble in dilute acid and ammonium salt solution, and its aqueous solution is alkaline. In the water, solubility is small, and is a strong electrolyte. Its natural mineral is brucite,which can be used for producing sugar and magnesium oxide, etc. Due to the rich content of magnesium hydroxide in nature, and its chemical properties and aluminum is close, so users start to use magnesium hydroxide to replace aluminium chloride when producing body products.

Application
1. The magnesium hydroxide is
excellent flame retardant for plastic and rubber products. In the aspect of
environmental protection as a basis for the flue gas desulfurization agent, it
can be used as neutralizing agent of acid wastewater instead of caustic soda
and lime. Also used as oil additivesto play the role of anti-corrosion and
desulfurization. In addition, it can also be used in electronic industry,
pharmaceutical, sugar refining, insulation materials and manufacturing other
magnesium salt products.
2. The goods can be used as flame retardants and flame retardant fillers added
to the polyethylene, polypropylene, polystyrene and ABS resin, and it has good
flame retarding and smoke suppression effect, join the amount of 40 to 20. But it
needs anionic surfactant treatment particle surface. The goods is also used in
magnesium salt, sugar refining, pharmaceutical industry, daily chemical
industry, etc.
3. At the same time it also can be used as a release of water vapor smoke
suppression agent. Magnesium hydroxide , which has the function of flame
retardant and smoke suppression, filling the triple excellent flame retardant is
widely used in rubber and plastic industry.
