Product Description

Product Description

Magnesium Hydroxide:by weight, consists of 58.62% of hydroxide and 41.38% of magnesium.
Chemical formula Mg(OH)2. molecular weight 58.33. colorless hexagonal crystal. relative density 2.36. almost insoluble in water and alcohol. Relative density 2.36. almost insoluble in water and alcohol, solubility in water (18ºC) is 0.0009g/100mL, solubility product is 1.2×10-11, aqueous solution is weakly alkaline. Soluble in dilute acid and ammonium salt solution. When the presence of water to absorb carbon dioxide in the air to generate alkaline magnesium carbonate or magnesium carbonate. In the alkaline solution heated to 200 ºC or more into hexagonal crystal system crystallization. The crystalline particle size, in general, is above 0.4μm. At 350 ºC decomposition into magnesium oxide and water. Above 500ºC, it loses water and transforms into magnesium oxide.
