'''硝酸钙'''<nowiki>[</nowiki>[[钙|Ca]]([[氮|N]][[氧|O]]<sub>3</sub>)<sub>2</sub>]是[[硝酸根]][[离子]]与[[钙]]离子化和生成的[[无机盐]]。为无色透明单斜晶体。

==物理和化学性质==
硝酸钙易溶于[[水]]、[[甲醇]]、[[乙醇]]、[[戊醇]]、[[丙酮]]、[[醋酸甲酯]]及[[液氨]]。置于[[空气]]中易[[潮解]]。硝酸钙是[[氧化剂]]，遇到[[有机物]]、[[硫]]等就会燃烧爆炸，发出红色火焰。于132℃分解；若再加热至495～500℃时会分解为[[氧气]]和[[亚硝酸钙]]；若继续加热则分解生成[[氧化氮]]气体和[[氧化钙]]。

==安全性==
硝酸钙对皮肤有刺激和烧灼的作用，皮肤接触会发红、瘙痒，也可能大面积的溃疡。应避免吸入其粉末。

<math></math>
==用途==
用于制造[[氮肥]]、[[煙火]]和[[硝酸盐]]。

==制取==
常将[[碳酸钙]]投入[[硝酸]]中制取硝酸钙：
:CaCO<sub>3</sub> + 2HNO<sub>3</sub> → Ca(NO<sub>3</sub>)<sub>2</sub> + H<sub>2</sub>O + CO<sub>2</sub>↑
