Magnesium hydroxide: A white, bulky powder. It dissolves in dilute acids, but is practically insoluble in water and in alcohol.
Magnesium hydroxide is a white to off-white crystalline powder with a specific gravity of 2.4 and a Mohs hardness of around 3.0. It loses 30.9% of its mass as water vapor on heating above 450°C. It being soluble in dilute acid and ammonium salt solution, but almost insoluble in water and alcohol. The solubility in water (18 ° C) was 0.0009g/100g.
Magnesium hydroxide is an excellent flame retardant for plastics and rubber products. In environmental protection, it is taken as flue gas desulfurization agent and can replace the caustrc soda and lime as the neutralizer of acid-containing waste water and the absorbent of the heavy metal. In addition, it can also be used for the electronics industry, medicine, sugar refining, as insulation materials and for the manufacturing of other magnesium salt products.
