Magnesium nitrate

Magnesium nitrate is a soluble, hygroscopic salt with the formula

Mg(NO₃)₂.6H₂O.

It is used in the ceramics, printing, chemical and agriculture industries. Its fertilizer grade has 10.5% nitrogen and 9.4% magnesium, so it is listed as 10.5-0-0 + 9.4%Mg.

It occurs in mines and caverns as nitromagnesite. This form is not common, although it may be present where guano contacts magnesium-rich rock.
