Molecular Formula: Mg(NO3)2·6H2O
Molecular Weight: 256.41
Physical and chemical properties: Magnesium nitrate hexahydrate is colorless crystal of monoclinic system, which is the most stable nitrate hydrates at room temperature. Specific Density 1.6363, Melting Point: 89℃. When heated above 90℃, it will thoroughly turn into basic salt. When heated above 330℃, it will thoroughly turn into magnesium oxide. It is soluble in water easily, and is able to dissolve in alcohol. It is likely to spontaneously combust if mixed with organic chemicals.
Applications and Usages: Mainly used in concentrated nitric acid as dehydrator, in producing explosives, catalysts and other magnesium salts, as well as incineration agent for wheat.
