'''硝酸铬'''(Ⅲ)，化学式Cr(NO<sub>3</sub>)<sub>3</sub>。

==性质==
硝酸铬是一种红紫色[[单斜]][[潮解]]结晶，易溶于水，溶于酸、碱、[[乙醇]]和[[丙酮]]。加热至100°C则分解。其水溶液加热时呈绿色，冷却后又迅速变为红紫色。<ref name="zghg">中国化工产品大全 上卷，Bc135 硝酸铬，页141</ref>

==制备==
由[[三氧化铬]]在[[硝酸]]存在下被[[蔗糖]]还原，再经过滤、滤液蒸发浓缩、冷却结晶、离心分离而得。<ref name="zghg" />

==用途==
用于玻璃制造、陶瓷釉彩、腐蚀阻抑剂，印染工业中用作[[媒染剂]]，无机合成用于制备含铬催化剂。<ref name="zghg" />
