Magnesium nitrate,hexahydrate

Molecular Formula:Mg(NO₃)₂·6H₂O
Molecular Weight:256.40
Physicochemical 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℃(decomosition).When heated a bove 90℃,it will thoroughly turn into basic salt,When heated above 400℃,it will thoroughly turn into magnesium oxide.It is soluble in water easily,and is able to dissolve in methanol and 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.
