Calcium nitrate

<p>Calcium nitrate are <a href="/facts/Inorganic_compound/TfFfzxSz">inorganic compounds</a> with the formula Ca(NO3)2(H2O)x. The anhydrous compound, which is rarely encountered, <a href="/facts/Hygroscopy/1NBGewXv">absorbs moisture</a> from the air to give the <a href="/facts/Water_of_crystallization/sbaKJNJX">tetrahydrate</a>. Both anhydrous and hydrated forms are colourless <a href="/facts/Salt_(chemistry)/lsSKwGpn">salts</a>. Hydrated calcium nitrate, also called <i>Norgessalpeter</i> (Norwegian salpeter), is mainly used as a component in <a href="/facts/Fertilizer/ysh3r6NJ">fertilizers</a>, but it has other applications. Nitrocalcite is the name for a mineral which is a hydrated calcium nitrate that forms as an <a href="/facts/Efflorescence/MVErNa6p">efflorescence</a> where <a href="/facts/Manure/1C2z9u3l">manure</a> contacts <a href="/facts/Concrete/K6whGVNx">concrete</a> or <a href="/facts/Limestone/8ntvtFnR">limestone</a> in a dry environment as in stables or <a href="/facts/Caverns/SNfJTJtM">caverns</a>. A variety of related salts are known including calcium <a href="/facts/Ammonium_nitrate/aSc96wBX">ammonium nitrate</a> decahydrate and calcium <a href="/facts/Potassium_nitrate/TycqMdcG">potassium nitrate</a> decahydrate.
